Compresor for Dur-Therm By Dometic AC for RV will not Turn off

I have a dometic roof AC unit that when I apply power the compressor will not turn off. It keeps running all the time and then will ice will form on the cooling fens inside the unit. Even as soon as I turn on the Electrical Breaker and compressor wants to run.
Is this a thermostat problem or a electrical problem with the unit, and how can I trouble shoot the problem?

Sounds like the contacts for the compresser are stuck closed.

I have a Dometic 15K roof Ac on my FW. After the AC reaches therm temp, the compressor and the fan turn off, but the fan starts right back up again and runs until you set the thermostat on off.


That is normal operation, only the compressor cycles, the fan stays running to keep air circulating for better temp control. Otherwise the rear of the space could get 5 degrees warmer than the front

RV Dometic Duo Therm roof top AC w/heat pump Model #630515.321El Serial #21631212 Yr. 2003. It is the rear unit, front unit working fine. In AC mode it is blowing hot air as if the heat pump is on. Fan...


If the Air comeing out is the same as the temp inside the RV make sure the compressor is running and not just the fans. It could be low on freon. If freon is ok then you would need to ck the wiring to the selector switch for a short. It would be obviouse because there will be melted wires. I am leaning toword low on freon since you have already been inside the wiring/control unit.

Front AC unit will not turn on


The clicking tells me the AC(hydro) power has been turned off to it. Check all breakers, and make sure if you have another switch on wall, to change from front, to back, or to both, that it is in proper position.

Duo-therm by dometic ac rv unit


I suspect that you have a bad selector switch for the on, off, low fan, high fan operation. If the selector switch is put into the off position everything should stop completely.

RV Dometic AC Comfort Control Double EE Problem


I have a dometic duo-therm. The unit works great and fan blows strong and both high and low work., but air is coming out of the ceiling unit rather than the duct work. The bedroom unit works OK, but the air is strong out of one duct, and not much comes out of the others. The front unit only has air coming out on the A/C unit and none out of the ducts.
