Troubleshooting Thermostat Function with Nothing Happening on Atwood Air Command AC with Heat Pump


It turned its self off and now wont come on. There is power to the thermostat and I can control it but nothing happens


Expert Reply:

Your Atwood Air Command Rooftop RV Air Conditioner w/ Heat Pump # AT15028-22 has separate power to the thermostat which runs off of 12 volts (battery) then the compressor and fan that run off 120 volts according to my tech contact at the manufacturer. It is likely since you have power to the thermostat and nothing else works that a circuit breaker for your 120 volt power has tripped and needs to be reset.
