Question about Dometic Rooftop RV Air Conditioner
My neighbor in the RV park has a Duo Therm Quick Cool high performance by dometic A/C unit. She tells me that years ago she had a heating element installed. When the unit is running the motor runs very slow and kind of groans. Then the motor will kick in to high, but then it will return to low and stay there for a few minutes and then return to high. And so goes..it just keeps cycling from low to high all the time it is running. The same set of events happen whether the thermostat is set to A/Cor to heat.
I tried setting the thermostat to high, medium, and low fan speeds but it does the same exact cycling thing.
I went topside and removed the shroud and the cover for the electronics and saw a circuit board, a capacitor and what looks like a relay. I was wondering if any of these electronic parts could be causing the problem. Thanks for your website. Bill Feliciano in Anaheim, CA
My RV ac works find when started up, blows plenty of cold air.after awhile ,it would seem to bog down, and blow very minimum cold air.the compressor will not shut down, possibly because it can't the cooling level that it was set for. model # 59136621
