Question about Dometic Rooftop RV Air Conditioner

1 Answer

I have a Duo-Therm RV Roof Air Conditioner Model 57915.622, Prod # 991731648, Ser # 84818800. It will not run. I changed the Compressor and Fan start capacitors. When I turn the unit on at the Thermostat nothing comes on. The Air Conditioner Control Unit E155095, Part # 3107541.009. The fuses are okay.

    Do you hear any "clicking" from control box in ceiling ? Verified AC power is there? What type of RV are we talking here? Does it require 12 volts as well to box, and is that 12 volts present?

Have Duo Therm roof mount A/C. Fan runs but when compressor tries to come on it just has a hum sound for about 10 seconds then after a short period of time it tries again but will not kick on


It sounds like the compressor is locked up. You can try a start boost or hard start kit but once this starts the compressor is on it's way out.

Compressor tries to start but want


hi,
you have to run a contractor grade extension cord(10-12 gauge) from your rv to run those or theyll do that, the lower the gauge the better, best bet is to plug the rv directly into the outlet, if you cant, get the shortest and thickest extension cord you can.

Sounds like 1 of 3. Blower motor capacitor, relay or thermostat. Try to run fan only if that is an option and see.
