I am having an issue with a Dometic roof air unit. I use the genset to power my ac units when traveling. The front ac sometimes cycles off, then comes right back on, runs a bit then goes off, back ...
The compressor should shut off before the fan. The compressor will cycle on and off as temp. nears the set-point. If both the compressor and fan are cycling on and off, there is more than likely an interruption of power to the unit. Start by checking you supply breakers for the AC. Could be some loose wiring.
