It is more likely a thermo activated "klixon' mounted on the sides of the compressor and the tripped because of low voltage which results in overheating. Normally klixons will reset with time but they may have a fuse component also. If the fans are running the problem is within the unit rather than in the coach. There is only one supply voltage to the units.
