Question about Dometic 57915531 Air Conditioner
I had the exact same problem, duo-therm AC unit on my RV the compressor ran continuosly, had to shut it off at the breaker. I too replaced the relay board thinking it was a stuck relay but the problem was still there. Good news is I found the problem. I took the cover off the thermostat panel inside the coach and found the thermostat wire marked "cool", was loose. I tightened this connection and the compressor shut down. Looks like the compressor and fan use seperated thermostat wires. Easy fix, and now I have a spare relay board that I didnt end up needing in the first place :-) Solution= check your thermostat connections at the terminal block inside your thermostat panel, they are probably loose.

E1-Automatic filter clean reminder.
Turn the air conditioner OFF and unplug it. NOTE: The air conditioner must be unplugged for the automatic filter clean timer to reset.
Clean the filter. See the Care and Cleaning section in your use&care manual. After cleaning, replace the filter and plug the air conditioner back in.
