A/C Coleman Mach compressor does not kick in

My 1991 Coachman Catalina has a two year old A/C Coleman Mach but the compressor does not kick in. Any suggestions as what to check rather than replacement

I assume the blower works..sounds like starting capasitor. Not expensive. Usually 3 wire plug.. under roof cover. DIY..

Check the start capacitor fro the compressor. If that is not the problem, check the start relay and for an open motor winding.

Could be total lack of 120V, bad breaker, no 12V power, bad thermostat, bad control board, bad capacitors, bad compressor, blown compressor overload. Need more info to trouble shoot.
