    Obviously short cycling.
    Replace the start relay and the capacitor.
    If that does not correct the problem replace the AC.

Sounds like the unit is low on freon. it will need to be serviced so the leak can be fixed then recharged.

Coleman mach rv roof ac, the fan comes on but the compressor doesn't, i've replaced all capacitors and stll is not comming on, how do i check voltage to the compressor to maske sure i have pow


At the compressor connectors you have a live and a neutral phase. The live usually goes to a ptc relay starting mechanism which you can test with a meter. If you can disconnect the relay and check the windings of the compressor from one pin to the other two it will tell you if the compressor is open circuit. It is more often than not an overload fault.

2 year old Coleman Mach III tapping and not blowing cold air:


Make sure the condensor fan is blowing through the condensor on the roof. It sounds like the compressor is fighting high head pressures after running a bit.. After so many attepts, or if it suceeds in operating the load trips the circuit breaker.. Make sure the condensor is clean and air is passes through it from the fan. Just for clarifiication the condensor is the coil that gets hot and the evaporator is the coil yat create the cold air. Good Luck, and if you will, let me know how it turns out. Good Luck. Ned

You will need 12 vdc (battery or converter) for controls to work, and 115 VAC (hydro) for fan & compressor to work. With your fan obviously working, that tells me you have both already but compressor may not be kicking in. Do you hear a "moaning" sound or see lights dim when switched to cool?
