• Can control the auxiliary fans of the HVAC system
• Hard to set the temperature to an exact value

6. Coleman 8330-3862 Digital Thermostat

The Coleman 8330-3862 Digital RV thermostat is the one that you need to get if you want the reliability and durability of a high-quality analog thermostat. Best of all, the device allows you to set the temperature to an exact value of your liking. You are getting an RV thermostat upgrade from the usual analog model.

One reason why many people like using digital thermostats is that they can set the temperature of their homes to an efficient level. Many people say that setting the thermostat to 25 degrees C (77-78 degrees F) and getting that exact value on a digital thermostat is no problem at all. It is not like a slider where you need to do a bit of guesswork.

Even though this heat cool analog thermostat is digital, you still install it as if it were an analog thermostat, so the wirings will not be difficult at all. The device requires no wiring to its LCD screen, and it runs on two AA batteries. Hence, you just need to connect this thermostat like you would with any analog mechanical type.

You can switch between the A/C and the furnace with just a flick of a switch, eliminating the need for separate controllers. This thermostat also allows you to control the fans. You can set it for the fans to turn on along with the A/C and furnace, or have it on all the time to circulate the air inside your RV.

• Allows exact temperature settings
• Easy to install as it only requires minimal wiring
• Easy to use with only a couple of switches
• Can control both the A/C and the furnace
• Optimal control over the fan
• The screen is small and does not have a backlight

7. Emerson M30 Thermostat

The feature that I like the most about the Emerson M30 White Heat-Only RV thermostat is its simple and straightforward structure. If you are looking for something minimalist, you need to look no further than this thermostat. You only need to manipulate one lever to set the temperature.

Aside from being high-quality and user-friendly, this thermostat also boasts of its durability and reliability. Because there is no sophisticated and fragile circuitry to worry about, this thermostat is very low-maintenance. At most, you just need to give it a bit of cleaning now and then.

You will not also encounter problems with the installation. First-time owners can follow the straightforward instructions and colored diagrams included in the package. It also only needs a couple of basic tools and around half an hour of your time to get this thermostat installed.

Another great thing about this RV thermostat is that even though it is a mechanical and analog unit, it still has an ambient temperature thermometer. It is great because you can monitor if the A/C is not working as it should (the set temperature is significantly higher or lower than the ambient) and have it fixed before it worsens.

• Highly durable and reliable
• Comes with only one lever to operate, promoting ease of use and operation
• Minimal wiring work needed for the installation
• Features a separate thermometer for the ambient temperature reading
• Compact and minimalist design
• Resets the temperature after turn off the thermostat

8. Dometic 3109228.001 Control Center

This product from Dometic is not just a simple thermostat. It is designed to handle all of the climate control capabilities of your recreational vehicle.

In detail, this digital climate control system can create up to four zones in your vehicle. A zone is a place in your RV where you can assign a different temperature setting. For instance, if your bedroom area has a different A/C unit, then that is one zone.

For something so sophisticated, this Dometic RV thermostat can afford a surprisingly breezy operation. There are only five control buttons and an on/off switch at the bottom. Each button also has clear labels, so you can easily figure out how to use this thermostat even without consulting the user manual, though I still suggest that you read it first.

This RV thermostat also has a large, backlit LCD screen that shows your climate control system’s status. You can see the temperature setting, but you will also see the fan status, the zone you are controlling, and other essential information. The screen is large enough that you can see the display clearly from a distance. I can do so even if I do not wear spectacles.

The best feature of this thermostat model is that it is compatible with all Dometic climate control products. In other words, if you are a big fan of this brand, you can freely control all of them using this one panel. It can make the interior of your recreational vehicle free of clutter.

• Can create up to 4 different climate zones in your RV
• Easy to use with only five buttons for operation
• Has a large and clear LCD screen
• Compatible for use in controlling all Dometic appliances
• Does not come with initial programming instructions

9. Coleman Manual Thermostat

Another straightforward unit that first-time users will love is the Coleman Mach RV Camper Manual Thermostat. Its switches have clear labels, making them easy to understand. You have one that turns on the thermostat and allows you to pick between the A/C or the furnace. There is also a switch that lets you control the fan.

Another feature that I like about this Coleman Mach thermostat replacement is the time and effort-saving installation task. You do not need to hire an electrician or HVAC expert to install this thermostat for you. There are only a couple of wires that you have to clamp into the thermostat and color-coded instructions to make the process even easier. Just make sure that you turn off the circuit breaker of your RV beforehand.

One major reason why I love analog thermostats is that they are tough as nails. There are no sensitive electronics and only a few moving parts (most of which you will rarely move at all), so the likelihood of anything going wrong is minimal.

Of course, this camper mach manual thermostat is not as fancy as the other devices, but you can be sure that this one will still be working well after twenty years have passed.

As mentioned earlier, you can use this one RV thermostat to control both the A/C and the furnace. Unlike other thermostats that are only for furnaces or A/C systems, you can hook up both the heating and the air conditioning in this one housing. There is a switch on the panel that will allow you to switch between the furnace and the A/C.

For me, this RV camper mach manual unit’s simple design scores big time as it matches my RV interior. Such a minimalist thermostat does not interfere with your RV decoration style, be it modern, classic, or simple.

• Simple and easy operation with clear label switches
• Easy to install, not much wiring work needed
• Can control the A/C and the furnace
• Durable and does not require a lot of maintenance
• Boasts of a minimalist design complimenting RV interior
• Does not have a Celsius scale on the temperature

10. Honeywell TH5110D1006 Thermostat

One thing that truly impressed me about the Honeywell thermostat is that it can run both on batteries and hardwired into the RV electrical circuit.

Some people like having their thermostat hardwired because it eliminates the need to replace the batteries every couple of months. Other users do not mind using batteries as they do not spend that much time in recreational vehicles. In that case, they turn off the thermostat when not needed.

Speaking of the battery, unlike other non-programmable RV thermostats where you need to remove this non-programmable unit faceplate to gain access to the battery compartment, the Honeywell thermostat has an accessible battery door at the side that makes replacing batteries easier.

Another neat feature of this RV thermostat is the substantially-sized screen. It is by no means large, but it is big enough for you to see the ambient temperature reading and the temperature setting easily. It works great for people who want a simple to use thermostat while still allowing them to set the temperature to an exact value.

Another nice thing about the product is that you can use it to control both the A/C and the furnace. You do not need a separate thermostat for each. It makes the interior of your RV less cluttered. You do not need to deal with a wall that is full of control panels.

• Features an easy to read backlit display
• Comes with an easy to access battery replacement door
• Can run on batteries or hardwired into the RV circuit
• Can control the A/C and the RV’s heat pumps
• Has a large display size for the ambient temperature
• Not as easy to install

11. Dometic 3314082.000 Comfort Control

What appeals to most RV-owners, including me, is a large screen for optimal control. Notably, this Domestic thermostat comes with a large screen that uses large fonts and a bright backlit, ensuring all operations are breezy in daylight or at night.

Just like the original Dometic Comfort Control, this one can also control up to four different climate areas. It means that if your RV uses two different A/C units or furnaces, you can use this thermostat to control them separately. This way, you can create different temperature zones within your RV. For instance, you can make the living area a bit cooler than the rest of the RV.

You can also use it to control several different Dometic HVAC products. You do not need a separate controller for your A/Cs, furnaces, vent fans, and others. It would also be unnecessary to deal with an entire wall panel covered with different controllers. You only need an RV thermostat like this one.

I also particularly like the clicky buttons on the control panel. I prefer having that tactile feel that tells me that I adjusted the settings. I feel it is much better than touch-screen panels. The buttons also make it easier to set the settings for a particular function.

• Features a large and easy-to-read display size
• Can control up to four different climate zones
• Can hook up to several different Dometic HVAC systems
• Features clicky and responsive buttons that provide tactile feedback
• Useful in controlling the air conditioner and furnace
• Has a somewhat steep learning curve

12. Coleman 83303362 Thermostat

One amazing thing about this Coleman thermostat is that you can operate it without consulting the instruction manual once. As long as you can read the switches’ labels, you will not have any problem using this RV thermostat.

Installation is also a breeze. You will only need to do minor wiring. It has a color-coded installation guide to make it even easier, so you will know which wire goes where. Unlike the traditional RV owner, I have no real experience with electricity, and I could still install my thermostat in under 30 minutes.

Another neat feature of this non-programmable thermostat is that it can control both the air conditioner and the furnace of your recreational vehicle. Just position the thermostat switch to what you want it to control. You even have switches for controlling the ventilation fans .

Because it is a digital-analog thermostat (alkaline batteries power the LCD screen), you can bet that it will last for quite a long time. The lack of sensitive electronic circuits and processors means that there are fewer things that can potentially break.

• Effortless to operate and use with few control buttons
• Easy installation, thanks to its color-coded instructions
• Highly durable – easily lasts more than five years at least.
• The screen is a bit too small.

Best RV Thermostats Buying Guide

Here is what you need to remember when you are shopping for the right RV thermostats – it will probably be the last one that you will ever buy if you are lucky. To make sure that you will not be wasting your time, energy, and money on a subpar RV thermostat to your expectations, here are some of the factors you have to consider.

Built-in features – In the past, RV thermostats were only capable of only the basic functions, including setting the temperature up or down. Nowadays, these best RV thermostats can do so much more.

Before you go shopping for a new thermostat, it is best to make a list of the features you would like to have. Would you like Bluetooth connectivity so you can control the thermostat using your phone? Or would you like the one that automatically adjusts, depending on the outside temperature and the number of people?

Are you looking for a programmable RV thermostat, or maybe you want something simple? If you prefer a simple one, you can just go with an analog thermostat. It is the most basic RV thermostat that you can get. It also usually just comes with a slider that lets you adjust the temperature up or down.

Types – Speaking of analog, it is one of several different types of RV thermostats that you can choose from. Analog thermostats are the oldest and most basic types. It would be beneficial to get these units if you are only looking for superior reliability and simplicity. However, aside from adjusting the heat or cooling of the A/C, you can’t expect these types of thermostats to do anything else.

If you want your unit to be a bit more sophisticated, you can choose the electronic RV thermostats. These models have the same function as analog thermostats, but instead of a slider, you have a digital LED screen that allows you to set the temperature to the exact value.

You can also go for the communicating type of thermostat. These units are the newest ones to come into the market. You can control this type of thermostat from anywhere using an app that you can open on your phone. You can do all sorts of things with this type of thermostat. You can even set what time the A/C comes on and what temperature it is set to.

If you want something lower-priced than a smart RV thermostat, but with similar features, you can get the programmable thermostats. These items work almost the same way, but instead of using an app, you tweak the settings right on the thermostat control panel.

There is no such thing as the top-rated RV thermostat as this term is subjective. Each one has its sets of pros and cons, so just choose the type that fits your needs and wants.

Durability – This factor can be quite hard to discern as it is almost impossible to figure out durability when talking about electronic devices. However, there is a consensus that analog thermostats are longer-lasting compared to the other types. The main reason is its simplicity. There are fewer components in analog devices so there are only fewer chances of them failing.

However, if you want to gauge the true durability and overall performance of a particular RV thermostat, you will need to check out as many RV thermostat reviews as possible. You can also hit up YouTube for video reviews. If most customer reviews say that the thermostat is quite durable, then it is safe to assume that it will be a good buy.

Warranty – You need to learn one thing here. If a company does not offer any warranty or return policy, then you should look for another thermostat, preferably from another company.

Look for a thermostat that provides at least a one-year return and exchange policy. The longer the warranty period is, the better the product is usually. You should have enough time to test and abuse the thermostat. The warranty should cover customer error and other serious failures that might happen during normal working hours.

It is safe to assume that the longer a product warranty period is, the more confident the company is with their product. It means that you are getting a good deal.

Customer Service – This factor is in conjunction with the warranty. Even if a certain brand of RV thermostat comes with an impressive warranty, then the warranty means squat if it is difficult to make a claim.

Good customer service will also come into play when you need help with setting up the device or getting a defective item. It should be easy to get in touch with the customer service department, either by phone, e-mail, or live chat.

It would be great to get a thermostat that works perfectly out of the box, but there will always be a setback feature. The best place to find out how good the customer service is in a particular brand is the list of RV thermostat reviews. If a certain company’s customer service is bad, you will undoubtedly read a lot of complaints about them.

How Many Types of Thermostats for RV Are There?

Ranked from the least to the most sophisticated, the different types of RV thermostats include the following:

Analog thermostat – This type is the most basic and the oldest unit of thermostat available on the market. If you are the type of person who is not a big fan of overly-sophisticated thermostats that come with a lot of bells and whistles, you will love the analog ones.

These units usually just come with sliders to control the A/C, so you will need to estimate the temperature based on the markings. Moreover, you cannot get an exact temperature setting.

Electronic thermostat – This unit is a step up from the humble analog RV thermostat. The great thing about this thermostat is that you will have a digital screen and set of controls that will allow you to set the temperature to an exact value, even down to the decimal values. However, other than that, electronic thermostats don’t do anything different from analogs.

Programmable thermostat – An RV programmable thermostat is an electronic device that comes with a couple of other features and settings. For instance, it has a feature that you can use to set it to turn on at a specific setting at any time that you want. You can also program the thermostat to change the temperature settings at certain times of the day.

Communicating thermostat – This unit is the most sophisticated RV thermostat that an RV owner can buy. It can do all the things that the other thermostats can, and probably more. These units got the name communicating because you can control and program your RV Wi-Fi thermostat from your smartphone.

How Does an RV Thermostat Work?

Most RV thermostats use the phenomenon of thermal expansion to help control the setting of your air conditioner. Thermostats usually use bimetallic strips or gas-filled bellows.

A bimetallic RV thermostat uses two strips of different metals fastened together; hence, the name. You will also usually see this unit using iron and brass as temperature sensors. Because iron does not expand as much as brass, the bimetal sensor will curve outward when the temperature gets higher. It can cut off the circuit that turns on the compressor of the air conditioner .

However, the problem with bimetallic temperature sensors in most heating and cooling systems is that they take a long time to react to temperature changes. An alternative to it is the gas-filled bellows temperature sensor. As the name suggests, this system uses two metal discs with a gas-filled bellow in between.

When the room warms up, the gas in the bellows expands and forces the two metal discs apart, turning on the compressor. However, when the room cools down to your desired temperature, the gas will contract, and the metal discs will get in contact with each other again.

Who Makes the Best Thermostat for RV?

Several brands sell RV thermostats, but as always, some of them are not as great as the others. I have used and reviewed quite many RV thermostats, and I can honestly say that the best ones come from Dometic, Honeywell, Suburban, Emerson, TycoonWon, and Coleman.

If you happen to spot these brands while you are out shopping for a new thermostat, you should at least check them out. I can guarantee you that these brands can leave a good impression.

How to Tell If an RV Thermostat is Bad?

If you feel that your RV thermostat is almost ready to check out, but you are still not convinced enough to bother replacing it, note that the RV thermostat troubleshooting.

If you see any of these problems, you should replace your thermostat immediately; otherwise, you will be spending your next RV trip without your A/C system, and that would not be any fun at all.

Sign #1 – The thermostat has no power/unresponsive

If you turn the thermostat significantly up or down, and you don’t feel any change in the temperature inside the RV, then the thermostat might be on the fritz. If you have an electronic thermostat and the screen does not turn on even if you just replaced its battery recently, then it may be broken.

Sign #2 – The heater or A/C won’t turn on

If you turn up the A/C and do not hear the compressor’s humming, then the problem could be either with the wiring or the thermostat itself. The thermostat turns on the A/C compressor and/or the furnace, so if it does not, it is likely broken.

Sign #3 – The A/C or heater does not unload and is running constantly

The thermostat is responsible for turning off the A/C and/or furnace when the RV interior reaches the desired temperature. However, if you notice that the A/C or the furnace is constantly running and does not unload, then it is a sign of a busted temperature sensor in the thermostat.

Sign #4 – The actual temperature and the thermostat setting do not match

This sign is a bit more subtle than the other RV thermostat problems, and you may need to bring a thermometer around your RV to check. If the temperature in the different parts of the RV fluctuates, you may need to change the thermostat for something a bit more accurate.

Can a House Thermostat Be Used in an RV?

It will depend on what kind of thermostat you will be using. If you will be using a thermostat that will require wiring it to draw power from the RV, it will not work. Household thermostats run on 24 volts AC, but the power source of RVs only produces 12 volts DC.

If the thermostat runs on its battery power, it might work on your RV. However, not all battery-powered thermostats will work on RVs, so you will be taking a chance right there. You should use a thermostat made specifically for RVs rather than risk wasting money on something that may or may not work.

How Do I reset My RV Thermostat?

Unless you are an RV owner using an analog thermostat, you will need to occasionally reset the settings. The thermostat settings can get all over the place, like when your kids played with it. Or, if you have reset it in a while, whatever the reason, you need to reset your thermostat regularly. Now, here is the problem; not all thermostats can be reset the same way.

If you are lucky to have a thermostat with an actual reset button, all you have to do is press and hold it for around five seconds or so, and the unit will restart with all of its factory settings. With other thermostats, you will need to press several buttons at the same time. You can see the exact combination written in the instruction manual.

If your thermostat does not have a reset button and misplaced the instruction manual, you can try several things. First, if your thermostat uses batteries, you can take them out for around ten seconds and then put them back in the sled. If it does not work, you can also try reversing the battery direction for a couple of seconds and placing them back in the correct position.

If you have a hard-wired thermostat, there is no other choice except to turn off the main circuit breaker of the RV for a couple of seconds then turn it back on. In case any of the tips mentioned above did not work, the only thing you can do is find the instruction manual of your thermostat.

However, it does not mean you will need the actual physical pamphlet. You can easily find instruction manuals nowadays online. You need to do a quick search for your thermostat model + instruction manual, and you will most likely find it on the first page of the results.

Care and Maintenance

You may think that your RV thermostat is nothing more than a switch that controls the A/C, but it is a very sophisticated technology piece. With that said, you need to take good care of it. Fortunately, thermostat maintenance is not that hard at all.

The most important thing that you need to do is clean the inside of the thermostat to work efficiently. First, turn off the A/C, and then remove the front plate of the thermostat. You can then use a soft brush or a can of compressed air to remove any dust accumulated inside the thermostat. While the cover is already off, you can use this chance to replace the thermostat batteries (if it is battery-powered).

You can do other things to make sure that your thermostat is working properly is to avoid placing any sources of heat beside or near it. For instance, you should not place lamps or televisions beside the thermostat as they can trip the temperature sensors.

Whether your existing RV thermostat is nearing the end of its service lifespan, or you want to replace it with something fancier, do not settle for anything less than the best RV thermostat.

Since you have made it to the end of this buying guide for RV thermostats, it is safe to say that you already know what you need to look for. You will not be wasting your time and money on something that you will not be happy with later.

RV Air Conditioners – How They Work (Complete Guide)

As summer heats up, keeping cool in your RV is essential for an enjoyable journey. Your RV air conditioning system is responsible for providing that much-needed comfort, but have you ever wondered how does RV air conditioner work?

RV air conditioners work similarly to home units. They use a compressor to pressurize a refrigerant, which absorbs heat from indoor air, cooling it. The fan then circulates the cooled air while expelling heat outside. This process repeats until the desired temperature is reached.

In this comprehensive guide, we’ll explain the science behind RV air conditioning and the key components that make it all possible.

Key Takeaways:

• Understanding the components of your RV AC unit is essential for troubleshooting potential issues.
• Regular maintenance can help extend the lifespan of your RV air conditioning system .
• Choosing the right RV AC unit depends on factors such as the size and layout of your RV, personal preferences, and more.
• Energy-efficient RV air conditioners can save on costs and lower your carbon footprint.
• Optimizing airflow in your RV is crucial for maintaining a comfortable interior climate.

Understanding RV AC Components

RV air conditioners perform the critical function of keeping your motorhome cool and comfortable during your travels. These units are complex systems assembled from various components with specific functions. Understanding these RV AC components is essential before we dive into how they work together to cool your RV.

The above components work together to pump refrigerant gas through the RV air conditioning system and cool the air blown into your motorhome. In the next section, we will explore the basics of RV air conditioning, which will help you understand how each component plays a crucial role in the overall functionality of your RV AC unit .

The Basics of RV Air Conditioning

What are the components of an RV AC unit?

An RV AC unit consists of several key components, including the compressor, condenser, evaporator, fan motor, thermostat, and air filters. The compressor and condenser work together to compress and cool the refrigerant, while the evaporator absorbs heat from the air. The fan motor circulates the air, and the thermostat controls the temperature. Air filters help clean the air before it enters your RV.

How does the mechanism of RV air conditioning function?

The mechanism of RV air conditioning involves a series of processes. The compressor compresses the refrigerant, increasing its pressure and temperature. The high-pressure refrigerant then moves to the condenser, where it releases heat and becomes a high-pressure liquid. The liquid refrigerant travels to the evaporator, where it expands and evaporates, absorbing heat from the air. The cooled air is blown into your RV, while the warm refrigerant returns to the compressor to start the cycle again.

What is the importance of maintaining an RV AC unit?

Regular maintenance of your RV AC unit is crucial for optimal performance and longevity. Proper maintenance can prevent issues such as refrigerant leaks, clogged filters, and malfunctioning components. By keeping your RV AC unit in good condition, you can ensure that it continues to keep you cool and comfortable during your travels.

7 Most common RV Air conditioner problems and how to fix them

• BEGINNERS GUIDE

G. Yoganand

Air Conditioning units (AC) on RV’s can be a great asset for those that spend a lot of time in them. But, on some occasions, some sort of deterioration or leakage can occur.

However, these may not be a very difficult situations to fix and it is possible for one to do it at home, provided that the right tools are used.

Troubleshooting a not working AC may not be difficult if you have basic knowledge about AC’s. Most RV’s are equipped with AC’s from atwood, coleman, dometic or advent. We recently replaced our old ac with a Dometic Brisk II Rooftop Air Conditioner (check current price and reviews on amazon). Its an awesome product, easy to install and replace.

In this article, lets explore common issues that we face with RV air conditioners and how to troublshoot them.

 Assessing the problem

When you detect that something is wrong with the Air Conditioning unit of your RV, the first thing to do is to see exactly what the problem is, in order to properly fix it. Now, it is important for you to keep in mind how old and how often your AC is used, as that can also influence the problem.

One can face varying issues with camper AC’s like “the RV ac shuts off on its own”, or the AC turns ON and OFF repeatedly or sometimes the AC wont blow cold air at all. There can be issues with the thermostat, or the capacitor in the air conditioner. So, how do you identify and repair these issues?

AC units are complex enough and may not always be fixed by RV owners. RV AC professional becomes a must then. But, sometimes its better to understand the problem and see if you can get it fixed yourslef.

Fixing the problem

Different problems ask for different solutions. Once you have determined what is wrong with your Air Conditioner, then you can move on to fixing it. Lets check out different problems that rooftop AC on RV or travel trailer can face and how we can fix those problems.

1. The AC Does Not Turn “O N”

When you have an Air Conditioner in your RV, usually you want it to work, and so, it can be quite frustrating when it doesn’t. The first step towards fixing it is to check for battery in the remote. Although AA and AAA batteries are known to last for a very long period of time, cheaper brands can wear out sooner than expected.

Generally, changing batteries should be sufficient, but if it is not, then the next step is to check whether there is anything broken in the remote. If your remote seems to be in good condition, then a simple, yet overlooked step is to check whether the electricity in the RV or motorhome is on.

2. The Air Conditioner Blows Out Hot Air

If your AC is blowing out hot air, then the first step is to check the thermostat. If however, you set the temperature right and the AC keeps blowing out hot air, then it is possible that the problem itself is in the thermostat.

To fix this, you will need to disconnect the wires leading to the thermostat and then attach them together, bypassing the thermostat entirely. If the AC starts working properly, then it is definitely a broken thermostat, to which you will need to buy a new one.

 3. The Air Conditioning Unit Motor is Unusually Loud

AC units are usually very smooth and silent and so, it is easy to notice when it starts acting up and making a lot of noise. This noise is very likely caused by the fact that the rubber shock absorbers are not in their rightful place.

To fix this issue, you will need to remove your AC unit shroud, find the rubber shock absorber and make sure that they don’t brush up against the fan or compressor coils. Here is a detailed guide on how to quiet your rv ac .

4. There is Ice on Your Air Conditioner

Although it is not a very common issue, ice can appear on the outer part of your AC unit. The problem itself is related to the Freon levels in your AC unit, but it is a rather easy problem to fix. The first thing you need to do is check if there are any leaks.

If you can’t seem to find a leak, then all you need to do is to top off your AC’s Freon. Afterwards it should work well again, not producing that unwanted ice.

5. The Air Conditioner Has a Foul Smell

Air Conditioners don’t usually leave smells, but on rare occasions, an uncomfortable smell can appear. This can happen when the filters aren’t regularly cleaned or replaced. If you do clean the filters and the smell remains, then the problem comes from the radiator. To fix this, you will need to clean all the dirt. Doing that should fix the problem.

6. The AC doesn’t stop running

If you notice that you try to turn off your AC unit, but it keeps running, then you will have to fix it right away to prevent damaging of the machine or decrease in longevity. There are a few reasons as to why your AC unit won’t turn off. First, it could be a busted thermostat, in which case you will have to replace it with a new one. If that does not appear to be the issue, then the circuit board could be affected, and so you will have to hire a professional.

7. The Air Conditioner is Leaking

Leaking is a common problem when it comes to Air Conditioners in Recreational Vehicles. Checkout my previous post on how to fix leaking RV air conditioner . Here, it is important for you to check whether it leaks when the AC is on or when it rains, and maybe even if it leaks in both situations.

Now, Air Conditioners are sealed to the rooftop of the RV with a rubber gasket. This gasket is usually very low-maintenance and so will require little attention. Nevertheless, if you start noticing that there is a leak, then you definitely should try to fix it as soon as possible, before it becomes a long term problem.

That being said, the first step towards fixing it would be to verify if the rubber gasket is intact. To do this, you will need to check whether there is at least) half an inch of height in the gasket between the Air Conditioner and the RV itself. If the rubber gasket really is the problem, then you will need to replace it with a new one.

Here, you can either hire a qualified RV air conditioning specialist or do it yourself. If you wish to do it yourself, then you will need a few tools:

• Screwdriver
• Wire cutter
• Rubbing alcohol

Once you’ve gathered all the necessary tools, then you can move on to fixing it. We carry this Black and Decker RV toolkit (amazon link) in our rig, it has most basic tools. That’s very helpful in fixing and installing appliances on RV.

First of all, you will need to remove the outer part of your AC, also known as shroud, in order to reveal its inner parts. After this is done, you will have to locate the bolts and remove them, placing them in a bag, so that you’ll find them easily when needed. Then you should carefully remove the shroud and set it aside, where you can easily reach it later.

The next step is to remove the Air Conditioning unit from the roof, as it will be much easier to work with. Remove the screws that hold the AC unit to the rooftop of your RV and set them aside. Then, you will need to observe whether there is an electrical connector and, if there is, what sort of connection there is.

Before cutting the three wires attached, you will need to make sure that the power is disconnected. Once it is disconnected, then you can proceed to cutting the three wires with a pair of cutters. After that, removing the Air Conditioner should be pretty easy, but be careful not to scratch the paint of your RV. Also, be vary of the fact that rv roofs support weight upto certain limit and therefore be careful when climbing up there.

Once the Air Conditioning unit has been removed from the rooftop, you can pull out the old rubber gasket and throw it away. If the rubber gasket is either stuck or hard to remove, use a knife to remove it.

Make sure that you remove all of the remaining residues and clean the entire rooftop with rubbing alcohol.

Moving on to the next step: Placing the new rubber gasket. On this step, you will need to return the AC unit to its rightful place, over the new gasket and reattach it, using the right tools. You will need to reconnect the wiring harness and then reattach the shroud.

Once your work is done, you will need to verify if everything is working properly. To do this, you should use a water hose to lightly spray the AC unit while it is running, and then check if there are any leaks.

Tips For The Future

Air Conditioners are practical and useful devices, but they do need some sort of regular maintenance, in order to function properly. Whether you own a class A motorhome or a fifth wheel or a small pop up camper, air conditioner are very important while camping.

That means that if you don’t wish to buy a brand-new AC unit every few years and don’t want to spend unnecessary money on air conditioning repair specialists, that you will have to dedicate some time to make basic maintenance a part of your routine.

Maintaining your Air Conditioner can be done in four easy steps:

1 . Protect from all elements

First of all, you need to protect your AC unit from all the elements. That means you should cover it when you are not using it. There are many covers out there for the buying and they are very easy to apply to your AC unit. This might seem like an expendable step, but it will protect your AC from dust and dirt.

2. Maintain and service the fan

The second step is to oil your Air Conditioner’s fan. It will run much more smoother if it is properly oiled. Note that every AC is different, and so, you should reach for your manufacturer’s instructions, to ensure that you do it properly.

You should buy a high quality oil that is detergent-free, such as automotive motor oil, as cheap oils might wear out faster and could leave residues that could later on become a problem.

3. Inspect the AC Condenser

Step number three involves inspecting the condenser of your AC unit. This step is important, as its coils will provide you with the cooling you seek in the hot summer days.

It is important to occasionally check the condenser as it can accumulate dirt, dust and other debris (as it is exposed to the elements).

4. Air Out roof vents

This last step is a considerably important one, if you wish to keep excessive moisture away from your RV’s Air Conditioning Unit.

In order to do this, you will have to air out the roof vent. It is quite an easy step and it will help you avoid a lot of unwanted and unnecessary issues.

Dometic RV Air Conditioner Operation and Maintenance Print

Modified on: Mon, 5 Jun, 2023 at 10:37 PM

Every RV has one or more Air Conditioners that helps keep it cool.   They do differ from household A/C units in a few ways, but just like household units, they do require some maintenance.  Below we will take you through the operation, maintenance and some diagnostic tips on a Dometic RV Air Conditioner.

Dometic RV Air Conditioner Operation and Maintenance

TABLE OF CONTENTS

Maintenance

A/c expectation of operation, diagnostics.

• Pushing the mode button will bring you into FAN Mode.   Pushing the FAN button will allow you to choose the fan speed for the unit. HI/LOW.
• If you stay in the FAN mode it will operate just the fan and the A/C unit will circulate Air on HI or LOW, but it will not cool the air.
• Pressing the MODE button again will bring you to COOL MODE showing you a snowflake in the bottom corner.  Dependent on the previously chosen fan setting will decide if the fan will run all the time on HI or LOW or AUTO.  If Auto was chosen the fan will turn off and on with the operation of the compressor.
• It is suggested during very hot summer months that the Cool option be operated in HI fan speed only not AUTO.

• Once the fan operation is decided in COOL mode you may use the up and down arrows to determine what you would like the target temperature to be.
• The thermostat has foam pads on the back of it that are sensitive and will break down over time if pushed hard.  The thermostat should be pushed as if it is a touch screen, lightly.  No need to mash the buttons.

INTERIOR MAINTENANCE

• Interior return air filters should be cleaned regularly.   If you have animals, it should be done even more.
• The screens are there to block any foreign objects from entering and clogging the flow of air for the A/C. If they are not cleaned regularly, it will reduce the efficiency of you unit.
• Most filters are screens or foam filters. The screens can be cleaned with a damp cloth or a blower on an air compressor.   Foam filters can be cleaned the same way or replaced with like material.
• The Mixing divider above the ceiling assembly should be checked yearly to ensure no air is being mixed between the return and output sides. This can cause your A/C unit to freeze up and not cool your RV.

EXTERIOR MAINTENANCE

• Exterior maintenance will require you to climb onto the roof of the RV.  
• Confirm all power and breakers are off to the A/C unit.

• Repeat the process as necessary to rid coils of dirt and debris to allow proper airflow through the coils for operation.

• When in COOL mode, the difference in air temperature the blowing out will be 20 degrees lower than the actual room temperature air that is being sucked into the return vents.
• This means if it is 100 degrees in the unit when you first turn on the A/C that the air coming out cooling the RV will be 80 degrees.  It will take some time for the RV to begin cooling to the point the room temperature is 80 degrees and the air output is 60 degrees.
• This could take several hours depending on how high the temperature is in the unit or outside the unit.
• This should not be confused with the A/C not working properly.
• If you have determined the air coming out of the vents is not 20 degrees lower than the air temperature in the room, there could be a couple of causes.
• One cause could be that the coils are frozen.  By removing the return air vents you can examine to see if there is a sheet of ice across the coils.
• If this situation exists, you should check the divider as suggested in the maintenance suggestion.
• This can also be caused by the compressor not operating properly for multiple reasons.
• In the event the coils are frozen you can turn the COOL function off and turn the FAN option to HI and allow the coils to defrost.  This will sometimes result in water dripping from the ceiling assembly.  You should lay a towel down below this to catch the water.
• Other causes of freezing up could result from the A/C being in an area of an entry point into the unit that is constantly being opened and closed allowing warmer outside air in.  This results in a lot of condensation and can cause the unit to freeze.   Reducing in and out traffic can help with this as well.
• If you cannot find a remedy to this, you should have one of our facilities check the unit to ensure there are no leaks in the system or other component malfunctions.
• If we have our thermostat operating either the FAN or COOL option, the fan should be running.
• In the event it is not you should check the breaker panel inside the RV to ensure there are no tripped breakers.  Also, check the power pole the RV is plugged into to ensure there are no tripped breakers there as well.
• If this does not resolve the issue it should be brought to a service center for further diagnostic.
• If the thermostat will not come on to operate the A/C you should check the 12-volt fuses located near the 110-breaker panel inside the RV.   Ensure the fuse is not blown.
• Also, ensure your 12-volt system is charging and you have a good battery.

Our Furrion Chill Air Conditioning System allows you to keep your RV or camper at your desired temperature. The 14 ,500 and 15,500 BTU rooftop air conditioners cater to different sized campers, while the different air distribution boxes feature a 3-speed fan and sleep settings to match your preferred comfort levels. An energy-efficient design means that you won’t be draining your RV’s battery excessively while using the RV air conditioning unit.

Our rooftop RV air conditioner units easily integrate into your camper or RV. Black and white color options help the system blend in seamlessly with a wide range of models, while an optional LED light on the Air Distribution Box adds dual functionality. In operation, Furrion AC units for RV are incredibly quiet at less than 80dB outdoor sound pressure level.

You can pair your rooftop AC unit with a manual control air distribution box or one with electronic control. For manual control AC units, you manually turn the unit on or off. It has a simple operation and is typically suitable for small RVs. Electronic control AC units include functions such as automatic restart and shutoff, so you don't have to constantly fiddle with the unit to keep the interior of your camper at a certain temperature. These RV air conditioning units are offered in either single zone or multi-zone controls. A single-zone unit with a thermostat lets you control the climate in a single space. For larger RVs, multizone systems are more suitable, as they let you control more than one RV AC unit with a single thermostat.

The Furrion Chill Air Conditioning System is built to complement life on the road in modern RVs and campers. Furrion Chill boasts 50% higher cooling capacity and 40% higher efficiency than industry standards. This means that you’ll get significant cooling power for the amount of energy it uses, ensuring you won’t run into flat batteries while staying off the grid. In addition, the RV and camper AC units are built with Furrion’s Vibrationsmart™ and Climatesmart™ technologies to protect the equipment from tough conditions on the road.

Furrion’s conversion kit allows you to easily replace your Coleman™/ Dometic™/ Advent™ Air Conditioning rooftop unit with a Furrion Chill AC rooftop system, while keeping your existing Air Distribution Box.

Dometic AC Control Board Troubleshooting, Wiring, Replacement

• May 24, 2023 /
• RV Air Conditioner /
• By James V.

When you are having trouble with your Dometic AC control board, the problem may lie with the control board or it may lie with some other part. It can be expensive and confusing to try and fix this issue yourself.

If the control board is bad, then your only repair would be to replace it. But you need to make sure it is the control board that is faulty. It could also be the relay, bad wiring, and other key parts that make up this system.

To learn more about troubleshooting your Dometic AC control board and other parts, just continue to read our article. It looks into the problem to provide you with the best information possible to help you get this problem solved fast.

Dometic AC Control Board Troubleshooting

You may find that any technician you contact will simply tell you to replace the unit. That is if the control board is the problem and has failed in some way.

That seems to be the only repair we have come across for this air conditioning component. One owner created a test box and when he added a thermostat to his system, he says it runs correctly, so the problem may not lie with the control box.

Replacing this part is not going to be difficult. You just need to find the right outlet or marketplace that sells the one that is compatible with your Dometic AC model.

What we also know is that there are none to a minute amount of people who talk about troubleshooting this component. They do as we will talk about other parts that are connected to this device as they may be the source or reason why your AC unit is not working.

The replacement cost is going to be at $100 or well over $100 depending on the unit you need. You can contact Dometic to see what they say and they may have a replacement part they can send you. Talk to your service department and see what they tell you.

Dometic AC Control Board Location

The location may be different from what we report here. That is due to the design of the different models of Dometic AC units. In the case of the 5-button AC unit, the control board is located on the front right of the unit.

It should be right behind the wiring diagram that is placed on the access door. Once you open up that door, you will see a capacitor and some wires blocking your way to the control board.

From there you can do your testing and removal if the controller is bad. Since the control board is inside the AC unit, you may have to get up on a ladder to access it.

That access may depend on where your access doors are. You may have to go on the roof to do this work or pull the AC unit down and work on level ground.

How To Test a Dometic AC Control Board

One instruction was to NOT use the voltmeter to make any tests. The reasoning behind this instruction is that this device does not provide you with an accurate reading.

Instead, you need to unplug the 6-pin connector, or whatever size connector you may have, and then get a 115-volt incandescent bulb to do your test. Here are the instructions for this test:

“ Using a 115-volt incandescent bulb, check from terminal 5 (white-common) to the other terminals to determine if a particular circuit is completed through the board. If the circuit is completed, the light will illuminate.

- Terminal 1 is a blue wire and is the compressor circuit.

- Terminal 2 is a black wire and is a High Fan circuit.

- Terminal 3 is a yellow wire and is a Medium Fan circuit.

- Terminal 4 is a red wire and is a Low Fan circuit.

- Terminal 5 is a white wire and is Common 115 V.

- Terminal 6 is a green/yellow wire and is casing ground.” ( source )

After doing these tests and the AC unit is not working, then you have a different source for your problem.

Dometic AC Control Board Wiring Diagram

If this wiring diagram is not matching what you see in your current RV’s air conditioning unit, then we would advise you to contact Dometic to see if they will send you one.

Different air conditioners will have different wiring diagrams. Check your manual as well to see if there is one on its pages. It may not be in the owner’s manual but it could be in a service manual that some companies provide.

Or contact your local Dometic dealer to see what they have available. It is not easy to match up every air conditioner Dometic has made over the years with just one diagram.

Dometic AC Control Board Replacement

According to the information we have come across, it is not hard to either replace the control board or find a new one. But first, how to replace one of these units so you can get your AC unit working again.

1. Replacing the control box

The first step is to shut off the power to your air conditioner. The second step would be to disconnect the wires. Make sure to mark each wire so you know where they go when you are ready to connect them.

The third step would be to disconnect the current control box and pull it out of its position. While you are doing this, you may need to remove the anti-freezing sensor so you can get the control box out without damaging anything.

After you have done all of that, take your replacement unit and put it in the old control box’s place. The fifth step would be to hook the anti-freezing sensor back up and put it in place as well as connect all the wires.

Re-connecting your wires will take the most time. You can take photos of the wires before you disconnect them, etc., and use those photos to guide your work. Some people suggest using end-to-end wire nuts to make your connections but that is up to you

You should use electrical tape as a back up and to make sure there are no opportunities for the wire to cross and create a short.

2. Where to find a control box

When you start looking for a replacement, make sure you have the model and serial numbers of both the control box and the AC unit. This will make it easier to find the right replacement.

We checked Dometic’s website and it does have a list of air conditioner parts and accessories on its web pages. However, there is a little note underneath the description stating it is not available online.

The website has a cart and checkout system but it seems that it is limited use or access to checkout. But that is okay, as you can find these parts at RV Parts Nation but you can expect to pay just under $200 for one model.

Amazon has several models available and the price range is from roughly $75 to well over $100. There are many other locations where you can pick this part up. The prices they charge will vary but they may be close to you so you do not lose any time fixing your AC unit.

Dometic Air Conditioner Control Panel Manual

The first place to go to would be Dometic’s website . They have a link on their support page where you can find the manual that you need. The link says FAQs, product manuals, and brochures.

Next, you can head over to our go-to manual website to view or download a copy for your records. It may take a little searching but you should be able to find what you need on that website. Just be prepared to pay for any downloading you do.

Then you can always do your own search for a more user-friendly website to get a copy of the manual. Another option would be to contact your local Dometic dealer and see if they hand out copies to customers.

Getting a manual should not be a difficult task as Dometic continues to make its air conditioning models. The YouTube video below should also be of some value to you as it shows step-by-step instructions on how to replace your control box.

The Dometic Air Conditioner Not Turning On

Depending on your model of air conditioner, you may find that there is always something going wrong at the worst time possible. When your air conditioner, no matter the model, does not turn on when you need it on, here are some steps to take to locate the problem.

1. Operation- this would be more of a matter of user error than anything else. Different Dometic AC models have different operating instructions and it is easy to make a mistake.

Review those operating instructions for your specific model to make sure you are doing everything right. Keep in mind that the unit won’t turn on if the temperature level is at the set mark on the thermostat.

2 . AC Voltage- the correcting voltage operating range is between 103 and 126.5 volts AC. You need to take the reading at the unit’s power supply leads. You will need to do two tests, one when the AC unit is off and one when it is under load.

If the air conditioner is not operating within that range, you will need to find the problem and repair it.

3. DC Voltage- if your unit has a DC supplied power control then you need to test it to see if it is receiving the proper amount of volts. The range for this option is between 10 to 16 VDC.

If your tests indicate otherwise, then you need to track down the problem and make the necessary repairs.

4. Breaker- this may have tripped for any number of reasons. Make sure to check to see that it has not tripped and that power is getting through to your air conditioner.

You can do that by taking an amp reading at the unit AC voltage supply line. If there is no power getting through, then you know where to look for the problem.

5. Wiring- this may seem like a minor component in comparison to everything else but if you have a bad connection, your AC unit will not operate. Check for corrosion, loose connections, and broken wires, and make sure to check the 6-pin connector to make sure it is tight.

6. Fuse- check for continuity first. The fuse may not look like it blew but it may have. Pull it out and do the test. If there is no continuity then the fuse is bad and needs to be replaced.

Also, you can do a DC voltmeter test to see if there is voltage. Put one lead on the fuse end and the other to the ground to see if there is voltage. If only one side has voltage, then the fuse is bad and needs to be replaced.

7. Thermostat- these can malfunction easily and when they do you should not be seeing your air conditioner operate. Use your meters to test the thermostats to see if they are functioning right.

8. Misc.- other components to check would be the cable array, ambient temperature, and the AC power module board.

Some Additional Words

It is given that electronic components in your RV or trailer will break down. The key is to make sure you have the right tools to diagnose the problem and then replace the failed part or parts.

The drawback to working on this issue yourself is that you may end up replacing more parts than you should and the problem may still continue. Make sure to get expert help when you are not sure what the source of the problem is or what the right fix should be.

RV Air Conditioner 15K Quiet AC Unit with Heat Pump, Remote Control

• Create New Wish List

Description

Warranty information.

Why choose this model? Well, the answers are simple and numerous.

• One of the best features of our Air Conditioner is the Dry Mode. Dry mode runs the fan at a higher speed, cycling more air through your rig and allowing moisture to collect on the coils before draining through to drain holes. Perfect for drying out hot, moist air!
• The second amazing feature to pay attention to is the temperature monitoring system. If you like to leave the AC unit on while you sleep, you can often wake up to a freezing room. Because our bodies are naturally cooler when we sleep, leaving on the air conditioner can make your morning feel like ice. To prevent this, the air conditioning unit has a temperature monitoring system that senses the temperature of the surrounding air and adjusts to accommodate whatever temperature you've set it to, keeping you comfortable even through the night.

• The low amp draw on this model enables it to not only keep your energy use lower than other models, but it allows you to use more than just the AC unit at one time. For other models that have a higher amp draw, you have to think about how many appliances are on that circuit, as the circuit breaker can only handle so much. With the low amp draw of this model, however, you have more room for other appliances. Saving you power and frustration, it's definitely the best model for energy efficiency.
• Because of the directional air tube, the high-quality design, and the efficient cooling and temperature control system, this AC unit produces air that is of very high quality. Temperature and humidity-controlled for your desired environment, you can feel the difference with this model.
• Our air conditioner uses an efficient heat pump to efficiently and effectively heat your air even at higher fan speeds, unlike other models that may use an inefficient heat strip.
• Perhaps the most important feature of this air conditioning unit is the noise level. Many of the models that come with your RV are loud and a bit obnoxious. Even those that you replace it with can be loud enough for you to notice it. This model, however, only produces 59.1 decibels of sound when on high. For reference, that's about as loud as a gentle rain; not loud at all. With this low sound level, you can relax in your RV, have a conversation, or watch your movie, all without competing with the AC unit.

*This AC unit requires a minimum 2500-watt generator with a dedicated 30-amp service. Using a lower-rated generator may cause difficulty when starting the AC unit or may require a soft starter.*

*It is recommended to use a 3000-watt generator with a dedicated 30-amp service.*

Ducted Information

This Ducted 15K Air Conditioner measures 13-11/16" high by 26-3/4" wide by 39-5/16" long for the outside unit and 1-11/16" high by 21-1/8" wide by 21-15/16" long for the inner plenum ceiling assembly unit. It weighs about 80 pounds and can be installed with a recommended two people. In the ceiling assembly, there is a removable screen filter that can be cleaned and replaced. Just make sure that when you do replace it, the screen is dry. Available in both black and white, the unit looks great on any interior or exterior RV design on the market today. Worried about something going wrong? The control screen on the remote or thermostat will show an error code to let you know the problem. Just make sure you keep the manual to interpret this code to fix it. While the external features of this unit are great, the internal features are even better. Why only have cooling when you could have both heating and cooling? The heating and cooling capabilities of this RV AC unit allow you to install it and use it for year-round camping. Included with the unit are the remote control which serves as the wall thermostat to control the unit. Because the unit is designed for this specific thermostat, it will not work with other pre-existing thermostats. It will, however, work with already installed ducts. The unit, controlled by either the remote or the plenum unit, has multiple functions, including cooling, heating, fan (with multiple fan speeds), dry mode, auto, temperature display and controls, clock, timer, sleep, and lock. These functions help give you the most control over your environment, creating a more comfortable and relaxing place for you to spend your vacation. Also, keep in mind that while this unit is rated for rooms up to 875 square feet, this number also depends on the layout of your air ducts, as they can help to carry the air into a bigger area. Perhaps the most important features of this unit are the noise level, the power draw, and the size. One of the biggest concerns with RV air conditioning units is how much noise they make. Because of the ones that come straight off the lot, RV AC units get a bad rap for being loud and annoying. This model, however, only creates 59.1 decibels of noise inside on the high setting. For context, that's about as loud as a soft conversation. Compared to the louder decibel levels of other standard AC units, that's a big improvement! Now, you can listen to music, talk, or just chill without needing to yell to be heard over the cooling system. These older air conditioning units also get a bad rap for being power-suckers. They have a large power draw, which means that they take up quite a lot of energy. Due to this, they're not so great for boondocking or power outages. Even with power, they're not going to leave as much for your other appliances. This model, however, only has a max power draw of 16Amps, leaving more power for your other items. The startup amp draw is the same as the maximum amp draw - 16Amp. Finally, because RVs have a weight and size limit, the items you add can make a big difference. With the economic size of both the outer unit and the inner unit, you have more space on your roof and ceiling while not adding more than 100 pounds to your RV load. As a quick note, this unit is designed to be installed on a flat roof (less than 5 degrees inclination) that is between 3" and 5-1/2"" thick.

The fan on the heat pump is controlled through a temperature sensor near the evaporator coils. Unless this sensor reads temperatures below 64°F, the fan will run at a low speed. This is necessary to modulate power consumption and keep up efficiency.

The air conditioner is non-ducted and comes in black and white. Attractive and durable, it runs off of 115V power. With this model, the sound level is much lower than many of the other air conditioners on the market and the quality of the temperature is better. If you've ever turned on your RV AC unit while you're watching your favorite show or talking to a friend, you understand how important the low sound level is. No one wants to have to fight over their air conditioner just to be heard. With the low decibel level of this unit (59.1, which is about the level of gentle rain or soft conversation), you won't have to fight to be heard above the unit. And when you're watching your movie or listening to your music, you'll only have the faint whirr of the AC unit in the background. In addition, the amperage (amps) on the model is lower than other air conditioners. While this might not mean a whole lot, it means that it draws less electricity, saving you power and money to use for other appliances or RV devices. With other models of RV AC units, you would have to be careful about whether you use your microwave or your air conditioner, due to the high amperage draw of the AC unit. This model, with its low power draw, lets you use both at the same time, saving power and giving you convenience. Plus, you don't need a start-up capacitor. These AC units also come with a remote for easy use. With this level of comfort and convenience, you won't need to even get up off the couch to keep your temperature at a comfortable level.

While the air conditioner is powerful and efficient by itself, there are several things you can do to lessen energy use even further and keep your RV cooler. Close all the doors, skylights, and windows so that the cool air does not leave and hot air does not intrude into your space. Also, draw the curtains and open the shade or awning to keep the heat from the sun from warming up your RV. Cook outside of the RV when possible and park your RV in the shade if there is shade available. Turn off any unnecessary appliances to reduce the energy load. Adjust the temperature of the unit instead of turning the unit off to prevent frequent starting or stopping. Finally, in the case of very high temperatures, turn on the AC unit in advance during the morning.

There is yet another tip that many people already use. In an RV, having just an air conditioning unit is a good way to cool down but also a good way to mess up the humidity in your RV. Instead of only pushing air into your RV, you should also push it out with a roof vent fan. By placing a fan at one end of the RV and an RV AC unit at the other end, you create a flow of air that will even out the temperature and keep the air cleaner. Many people place the fan over their kitchen and the AC unit at the opposite end of their RV. This is because of the smells, heat, and humidity that can build up around the kitchen, with all of the cooking and food from that area. With your air flow set up in this way, your RV interior will feel cleaner and more comfortable.

Maintenance

There are also steps you can take to maintain the unit and lengthen its life. Though there are several important parts to the unit, the return air filter is the only part that needs regular maintenance. Clean and check the filter each week when in use to keep it clean from dirt, washing it in warm water and a little detergent frequently to ensure effective heating or cooling. Make sure it's dry before you replace it. You should also check that the bolts holding the unit on are still stable after the first three months. Throughout the life of the unit, these bolts should be checkers once a year. If you only use the unit on occasion, then the unit should be operated for 20-30 minutes every six months.  This AC Unit comes with a preinstalled gasket.

Frequently Asked Questions

How to choose the right rv air conditioner.

Before buying an air conditioning unit for your motorhome, you should consider the climate of the destination you are traveling to. This can help you calculate how AC power you will need to stay comfortable. Before you turn it on, you'll need to ensure you have enough power to run your new AC unit in your RV, and power for all the other appliances you plan to run in your RV. You should also consider bringing solar panels for your RV to add to your power reserves. 

How to install an RV air conditioner

If you're installing the AC unit yourself be sure to exercise caution. Every air conditioner has its own proper installation technique, so consult all available instructions before starting your installation job. Here is a YouTube tutorial from All About RVs on how to install an RV air conditioner properly.

Are there any drawbacks of RV air conditioners?

Energy consumption will be much higher with the AC running, especially with other devices running simultaneously. According to To Go RV , “An RV air conditioner can consume upwards of 2,400 watts on start-up and then level out to around 1,500 watts as it continues to run. RVers can quickly exceed the available wattage by operating other appliances, like a microwave, electric water heater element, or refrigerator at the same time.”

Ukraine marks its third Easter at war as it comes under fire from Russian drones and troops

For a third year running many Eastern Orthodox Christian Ukrainian soldiers are celebrating Easter on the front lines. It’s a busy time of the year for members of the church, including frontline Priests like Ivan, Chaplain of the 72 Mechanised Brigade of the Ukrainian Army. After driving to a Ukrainian army position in the dead of night, he held a short service with soldiers and blessed Easter cakes that would end up with troops in and around the frontlines.

KYIV, Ukraine (AP) — As Ukraine marked its third Easter at war, Russia on Sunday launched a barrage of drones concentrated in Ukraine’s east, wounding more than a dozen people, and claimed its troops took control of a village they had been targeting.

Ukraine’s air force said that Russia had launched 24 Shahed drones overnight, of which 23 were shot down.

Six people, including a child, were wounded in a drone strike in the eastern Kharkiv region, regional Gov. Oleh Syniehubov said. Fourteen more were wounded in an airstrike Sunday afternoon on the Kharkiv regional capital, also called Kharkiv, the regional prosecutor’s office said. Syniehubov said the city was attacked by an aerial bomb.

Fires broke out when debris from drones that were shot down fell on buildings in the neighboring Dnipropetrovsk region. No casualties were reported.

The Russian Ministry of Defense announced Sunday that its troops had taken control of the village of Ocheretyne, which has been in the crosshairs of Russian forces in the Donetsk region of eastern Ukraine. Drone footage obtained by The Associated Press showed the village battered by fighting. Not a single person is seen in the footage obtained late Friday, and no building in Ocheretyne appears to have been left untouched by the fighting.

Officials in Kyiv urged residents to follow Orthodox Easter services online due to safety concerns. Serhiy Popko, head of the Kyiv city administration, warned that “even on such bright days of celebration, we can expect evil deeds from the aggressor.”

In his Easter address, President Volodymyr Zelenskyy called on Ukrainians to be “united in one common prayer.”

In a video filmed in front of Kyiv’s Saint Sophia Cathedral, wearing a traditional Vyshyvanka embroidered shirt, Zelenskyy said that God “has a chevron with the Ukrainian flag on his shoulder.” With “such an ally,” Zelenskyy said, “life will definitely win over death.”

A majority of Ukrainians identify as Orthodox Christians, though the church is divided. Many belong to the independent Orthodox Church of Ukraine. The rival Ukrainian Orthodox Church was loyal to the patriarch in Moscow until splitting from Russia after the 2022 invasion and is viewed with suspicion by many Ukrainians.

In Moscow, worshippers including President Vladimir Putin packed Moscow’s landmark Christ the Savior Cathedral late Saturday for a nighttime Easter service led by Patriarch Kirill , head of the Russian Orthodox Church and an outspoken supporter of the Kremlin.

Eastern Orthodox Christians usually celebrate Easter later than Catholic and Protestant churches, because they use a different method of calculating the date for the holy day that marks Christ’s resurrection.
