Guy, at the risk of derailing this thread. I love the Dometic basement air. They will freeze you out if working properly. It sounds like you condenser motor has gone out. It is the number one problem with that unit. The bushings wear, and the motor doesn’t start. When the condenser motor doesn’t start, the compressor develops high head pressure very quickly, hence the high amperage you see. Replacing the motor isn’t that hard. Usually there is enough copper line in the refrigeration lines to just slide the unit out far enough to get the top off of it. Look up the threads on replacing that motor. The original is a weird rpm, but a number of people have used a commonly available Grainger motor with a slightly different RPM with success. You do have to take saw or side grinder and “adjust” the length of the motor shaft.
