Question about Coleman Mach 15 Air Conditioner
I just bought a rockwood popup camper and the a/c unit will blow the fuse when the compressor turns on. Everything works on the a/c unit just not the high cool setting. I'm thinking it might need a 30amp.
It is possible that the compressor has completley failed and is shorted to ground. The way you check is to access the compressor terminals where the wires hook up. After noting the location of each wire, remove the wires from the compressor terminals. Get a piece of sandpaper and shine up a small area on on of the copper pipes coming out of the compressor. Use an ohmmeter and check for continuity between each one of the compressor terminals and the copper pipe. If you have ANY continuity from any terminal(s) to the pipe, the compressor is dead and will require replacement. If not then check all of the wiring to and from the compressor looking for any possible shorts to ground (wire chafing, cuts, etc.) After that, check the run capacitor for the compressor. If the capacitor is failed, it will cause the compressor to draw locked rotor amps. Generally speaking, the quick way to tell if it is a capacitor or a short is to listen to the unit. If it trys to start for a couple of seconds and the pops the fuse, either it is the capacitor or the compressor is seized up. If it trips the very instant that it trys to come on, it is a short.
