If you are planning a summer road trip in your RV, make sure you’ve checked the air conditioning system in your RV first. Why? Well unless you don’t mind sweating it out during what should be a trip filled with fun and adventure, it’s always good to know you’ll have plenty of that sweet, sweet cool air.
And while you’re at it, why spend money for a technician if you can do the RV air conditioner repair by yourself?
Why not be your own mechanic? Discover the basic how-to of RV air conditioner repair! It’s easy…and it’s free!
Start with the Basics: 2 Main Systems of an RV Roof Air Conditioner
- The Sealed System: This contains the inner workings of the air conditioner. Here you will find the compressor, condenser & evaporator. These all important components work together to cool the cool air.
- The Air Moving System: Here you will find a motor and two fans. One fan moves the air across the condenser and one moves it across the evaporator.
Occasionally one of these systems experiences an issue causing the air conditioner to not work as it should. Don’t panic!
Tips for Common AC Problems
You went outside to set up a grill, and when you go back into the RV the air conditioner won’t even turn on.
First begin by checking the power supply to the RV by plugging something into a 110v outlet. All good? Okay, how about checking the breaker? Chances are good you tripped the breaker. Invest in a multi-meter and test the voltage coming into the RV. If that doesn’t work, call 911. No wait! You’re being ridiculous, don’t do that.
It’s a hot day outside. After several hours of cool air, you notice that the air inside the RV has gotten hotter.
There are several potential causes for the AC not keeping the air cool in your RV.
- The AC unit could be old. It’s not unusual for RV AC units to not cool as well after a few years of use.
- It could simply be too hot outside for your AC to keep up. Depending on the size of your RV, you may need to install an additional unit to keep up on hot days.
- The air filters, fins, and coils are dirty! A build up of grime can dramatically decrease the efficiency of your AC unit.
