Capacitor is good place to start, once you confirm you have proper voltage getting to the unit.

That should be a 30,000 Btu unit. Its been a while since I worked on them. The 78 is the series or model, the 30 is the capacity or btu's and the 901 indicates it is a Copeland compressor.

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.

Coleman mach 3 rv roof mount ac


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?

Coleman RV roof air


I think you have a high pressure switch that has tripped. open up the case and look for a switch connected to the line with a resettable button in the case it is not resettable you will have to have a professional replace it. If you are able to reset it make sure to clean the condensing coil on the top side before running it again as most likley this is what may have caused it to trip.
