Most Common Reason Your A/C Went Out In Your RV | Mid Florida RV Services

Updated: Apr 14

Your RV's A/C is a great asset but eventually, you're bound to have a problem with it. Sometimes these are problems that you can easily fix yourself. Here are some common issues with RV A/C units.

The A/C Doesn't Turn On

When your RV A/C won't turn on, you should first make sure that the batteries in your remote are working. If, after you've changed the batteries, the unit still won't work, you should make sure that the remote isn't broken. Once you're sure it's fine, check whether your RV's electricity is turned on.

The A/C Is Blowing Hot Air

The first thing you'll want to check is your thermostat to make sure that you've set the temperature correctly. If so, you may have a problem with the thermostat itself. You can fix this by disconnecting the wires that lead to your thermostat and attaching them to completely bypass the thermostat. If this works, you'll know it's time to buy a new thermostat.

The A/C Is Unusually Loud

When RV A/C units aren't running smoothly and silently, it's probably because the rubber shock absorbers aren't in the right place. You can fix this by making sure that they're not rubbing against the fan or compressor coils.

Ice On Your A/C

Ice on the A/C isn't a common issue but when it happens, it's caused by your unit's Freon levels. You'll want to make sure that the unit isn't leaking. If there's no leak, then it's as simple as topping off the Freon. Once you've done so, your RV air conditioning should work fine and you should have no more ice.

The A/C Smells Foul

You'll rarely smell anything from your air conditioning unit but if you do, it may be because of the filter. You should clean and replace them regularly. If you do this and there's still a smell, it may be coming from the radiator. You'll need to clean the dirt out of there as well.

The A/C Is Continually Running

If your A/C unit runs even when you turn it off, get this fixed right away. If not, the unit may end up damaged or with a shorter lifespan. Some reasons why this may happen include:

A busted thermostat that needs replacing.
A broken circuit board in your A/C unit. Unfortunately, you'll need to hire a professional to fix this for you.

The A/C Is Leaking

A leaking A/C unit is a common problem. To determine what's wrong, you must first assess when it's leaking: when the A/C is on, when it's raining, or in both situations. Since your A/C is sealed to the roof of your RV with a rubber gasket, you should also take a look here. Usually, it won't require much attention, but if it's causing the leak you should fix it as soon as possible.

Start by making sure that the rubber gasket is still intact. There should be at least half an inch of the gasket between your A/C unit and the roof of your RV. If there isn't, you'll need to either change the gasket yourself or hire a professional to do the job for you.
