How to Fix Common RV Air Conditioner Problems: RV Troubleshooting 1
From not pulling power to not cooling down to tripping a breaker, there are a few common problems that go along with RV air conditioners. But with a better understanding of how your RV air conditioner operates, there are several simple troubleshooting solutions to remedy these issues and ways to maximize your appliance's efficiency. Let's take a look at a few common problems and troubleshooting solutions for your RV air conditioner.
Troubleshooting: Tripped Breaker
Here's what to do when your RV air conditioner continually trips the breaker at the pedestal or in the electrical panel of your RV.
(1) Low voltage can cause an increase in amperage moving through the air conditioner, which causes its breaker to trip at the electrical panel inside the RV. Low voltage can be just as harmful as a high voltage spike and should be monitored by an EMS when plugged into shore power to prevent damage to all of your appliances.
(2) Or, you could be exceeding the potential watts available for your RV by operating other 120-volt appliances at the same time. Keep in mind that when plugged into shore power, the converter always consumes 120-volt AC at various levels while charging the 12-volt DC coach battery. Plus, if you have a water heater or your refrigerator is set on electric, their combined use can trip the breaker outside at the pedestal. Turn off one of the other appliances before running the air conditioner.
Troubleshooting: Varying Performance Based on Location
If you travel between different climates, you might notice that your RV air conditioner performs better in dry areas like Arizona than it does in more humid locations like Florida.
(1) More humidity in the air means a lower "Delta-T" reading-this refers to the change in temperature between the return air and supply air. The air conditioner will continually run trying to overcome and dry off the evaporator coils. A dehumidifier inside your RV will help.
(2) High humidity can also cause the evaporator coils to freeze and restrict airflow, which can produce warm air at the supply. Keep your fan speed on high and open the air dump feature instead of using individual registers and vents to regulate temperature.
What's the Fastest and Most Efficient Way to Quickly Cool Your RV?
Simply use the air dump feature. Close off all of the individual vents and registers and let the air from the rooftop unit dump straight down into the RV.
You can also turn on your generator and run the air conditioner during the final leg of your journey (yes, you can operate your generator while driving). While you drive, heat is absorbed into your rig, including in the walls, cabinetry, furniture, and flooring. Give your RV a head start by cranking up the generator and running the air conditioner before you arrive at the campground.
