I'm assuming when you say 'doesn't work' you mean 'nothing comes on,' i.e. The fan or the compressor. If that's the case I would check for the AC breaker to see if it's tripped. Usually a 'tripped' breaker will look half on and half off, but sometimes it will be completely in the off positiion. Either way - it's usually because of a malfunction of the AC unit, so if that's the problem I would moniter it closely to see if it trips again. If it trips again in the immediate future I would then want to investigate the AC unit for the cause. Also, some RV's have fuses in the AC circuit - so you could check and see if you have any fuses labled AC or AC control voltage.
Dometic 13500 air conditioners is the world's number one style of roof air conditioner available. Dometic also offers the low profile Penguin RV and camper air conditioners as well as the 15000 BTU AC unit to provide you with extra cooling. Refer to this manual. For assistance or additional information consult a quali-fied installer or service agency. Mounting on the roof of a recreational vehicle. Connection to an air distribution system located in. The Dometic Air Conditioner Control is a sophisticated.
If so - you can usually - tell by looking whether they are bad or not. If that's not possible try replacing your 'AC labled fuse' with a new one of the same size. I would also check your power supply (where the power cord to your RV plugs into) to make sure it is providing the proper voltage to your RV. Note: They also have breakers out on the box that you can reset.
If they (breakers) appear ok - and you are at a RV park you could have the Park personel - check and to be sure the proper voltage is availible to your RV. Good luck! Answered on Jan 11, 2019.
Something To Keep In Mind Most RV air conditioners are not designed to be opened and repaired, and if a repair is possible it is often very costly. It is an unwritten rule most RV Tech's go by to replace any roof AC over 10 years old with major problems.
Replacing a bad compressor is just not cost effective on an older unit, and if a unit has lost its charge then it has a leak and is not cost effective to repair that either. So save some money in the long run and replace instead of repairing your old AC. Why isn't my AC cooling properly? The most common issue involving RV air conditioners is it is not cooling enough.
There are a few things you can look for when your AC isn't cooling properly. Your AC just might not be strong enough.
On a hot day your air conditioner could be outmatched. You could consider getting a second AC installed or upgrading your current AC. The rate at which your air conditioner can cool is measured in BTUs-the more BTUs the stronger the AC. If you believe your RV air conditioner is plenty big but is not cooling to its potential, there are a few things you can do to improve efficiency by maintenancing your AC. RV Air Conditioner Maintenance Air Filters. It is best to clean your RV air conditioner's air filters every 2-4 weeks depending how often you are running it.
If you are not diligent in cleaning your air filter you will decrease air flow and not get the cooling you need on a hot day. If you ignore your air filters for a long period of time without properly cleaning them you will run the risk of needing an expensive cleaning by an RV repairman. The moral of the story here is simply not to overlook your air filters and complete an easy and painless cleaning every 2-4 weeks that will save you money.
Remember a dirty system causes the unit to work harder, and this uses more power. Not only does the extra power cost you more money electrically, but it also hits you by shortening the life of the AC. Condenser Fins Condenser fins are really something you should avoid messing with , but it is good to know a little about them so you can know what to look for when maintenancing your air conditioner.
If the condenser fins are very dirty, remove the filter on the inside on the ceiling. Get a flash light and look up at the condenser fins, they should be clean and clear.
It would be a good idea to call an RV repairman if they are dirty. You really have to be careful not to damage these fins when they are being cleaned. NOTE: If the condenser fins are dirty, then your filer is not covering the intake area completely as it should and needs to be replaced with the correct size.
NO dirt should be able to get by this filter. Inspect your condenser fins occasionally to check if they are bent. If they are, you can straighten any bent condenser fins on your air conditioner with a fin comb. Condenser Coils Clean the outside condenser coil as needed. This is not an obligatory maintenance concern. I'd rather you worry about your batteries than worry about your condenser coils. But if you feel the need it is ok to blow them clean with compressed air.
The coil is located at the back of the AC Unit and can be accessed from the outside on the roof. You can blow out any debris which may have collected on the coil with an air compressor. Because the AC fan pulls air in through the back of the coil and exhausts it from the sides of the shroud, it is best to blow compressed air through the coil from the inside out.
You may also wash this coil with water if you choose to do so. Don't forget to disconnect all power leading to the air conditioner first. Each AC unit has a pan to collect the water as a result of condensation and directs the water out on to the RV roof through a small hose.
Some of these drains on the pans have small openings and can be easily blocked causing the water to leak into the RV. The holes can be cleaned out with a wire carefully and blown clear with air.
Whenever your RV air conditioner is receiving too much or too little power, it is at risk of some major damage. There are many ways you could be receiving the wrong amount of power, including the following: Your generator might be fluctuating too much, meaning you might have an internal problem with your generator. If you are plugged in at a camp ground and it is a hot day, most people could be using their air conditioners. This would affect how much power you receive from the shore power outlet and could potentially harm your air conditioner. Still troubleshooting?
