Answers :

Turn the ac off go up top the coach and remove the cover. Look for fan blockage, Wasp, mud dauber etc. Caution if it is wasps they will chase you off the end of your coach. Take some spray with you. If there is no blockage the fan motor is toast.

My duo therm brisk air roof mount ac unit is blowing warm air, the amp draw on both the run and start lines is 3 amps, the compressor is hot, the condensor is not warm, the voltage across the run to common on the compressor is 120 vac and the voltage across the start-common is 300 vac. It appears there is an oily substance on one of the lines, perhaps the freon has leaked out.

Dometik Duo Therm Brisk Air rooftop trips AC circuit breaker when the weather turned hot. When circuit breaker is reset, the unit will run for 5-10 minutes, cooling nicely, and then trip the AC circuit breaker again. I changed the settings, but it did the same. Once the outside temperature went down, that evening, I tried it again. The AC worked fine all night and the next morning,and when it got hot outside next morning same thing, trip the breaker

Don't panic, but I have a question about my 40 year old duo therm RV roof top AC. I know, it shouldn't be working, but it does. My problem is it will kick on, compressor starts to work and puts out cold air, then I hear the relay kicking out and it stops putting out cold air. This past fall I took the shroud off and cleaned everything and observed the operating system. Again, it starts, runs for a minute or so, than the relay opens. If I push on the relay, it will run again. A friend suggested a


When you say relay I'm assuming the contactor. Does it shut off again when you let go of the contacts (relay)? Most likely it's low on refrigerant and the low pressure switch is shutting it down. ... Dometic Rooftop RV Air Conditioner

It sounds like it. You may have caught it in its beginning stages of running low. Are you getting any frost or ice on the suction line at the compressor? (The larger of 2 lines). That is a sure sign. Let me know if you need to go further. Roger ... Dometic Rooftop RV Air Conditioner

I have a Duo-Therm, mod# 600315.321 on a motorhome. Fan motor overheats, but only after the compressor kicks on. New motor, swapped out caps w/identical working unit. Ground is good. Unit will run all day OK w/just fan, but when put on "cool", it will run and produce cold air for 15 min, the fan then quits. Compressor will run for 5 - 10 minutes more by itself, then the circuit breaker kicks.

I have a Duo Therm Quick Cool, model 59516331, mounted on a 2001 Dutchman. With the A/C on it cools great but the compressor does not kick out or cycle. The unit runs until it freezes and can't blow air. When I shut the unit off manually from the thermostat the compressor continues to run, the only way to shut it off is to shut the breaker off. I am wondering if it could be the thermostat? I have checked everything I can think of. Any advice for me?
