The air conditioning system in the RV can show a flurry of problems but which one could be the most annoying one? Well, many will agree that the trouble of RV air conditioner turns on and off repeatedly wins this competition, by a mile.
How do you feel when the AC cycles on and off every 10 minutes, or even worse – every 2 minutes? The issue is known as short cycling and it can lead to expensive repairs and high energy bills.
It becomes intolerable, especially during the scorching summer days, when the air conditioner shuts off every few minutes. Plenty of different things can trigger this problem. Here are some of the most common causes:
Most RVers set the thermostat to the ‘automatic’ setting. When it does not work properly, it may cause the AC turns on and off again and again. Wrong placement (near the windows or air vents) of the device can also create the same issue.
When cool air from the air vents blows over the thermostat, it turns off the AC thinking that the home is cool enough. Likewise, it may turn on the AC when sunlight comes through the windows and heats up the surrounding area.
The AC system has a control board and a failing control board can cause the air conditioner to cut on and off in a repeated cycle.
There are evaporator coils inside the air conditioning system. When the RV air conditioner turns on and off repeatedly during nights or humid days, freezing evaporator coils are likely to be the culprit. The coils can also freeze due to refrigerant leak so check for any puncture or crack.
Like any electronic device and system, the air conditioner needs regular maintenance, cleaning, and repairs for functioning normally. It will keep turning off and on if dirt gets into the air filter and condenser coils.
The grimy or clogged filter restricts airflow to the point of shutting down the system. When the condenser coils get filthy, they cannot dissipate the heat, making the AC to struggle, overheat, and shut down.
