Dometic rooftop a/c compressor will not shut off.
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.
Rewire 12Volt into 24Volt
You have to get you a transformer .voltage input 120 and out put 24 volts.But will have to wire it through a relay or contacter with the coil volts 24.
Starting amps 15000 btu ac
with a good start capacitor you will not have time to read starting amps. it should drop to running amps almost instantly.
I meant the AC does not cool
Make sure the mode is set to freeze and temperature is set to below the room temperature.
If it is a split system, check the outdoor unit whether it is running. If it is running, see if you can reach and feel the temperature of the pipes connecting between the indoor and the outdoor unit. It should be cool.
If it is not cool, you may need to get somebody to check the refrigerant.
