Question about Coleman Mach III Air Conditioner

A/c won't start

When I turn the a/c on it only humms and then shuts off. If I start the fan first it will blow air fine but the compressor still hums and shuts off

    When you start the fan first, the compressor hums and shuts off but does the fan shut off as well? Does the compressor try to kick back on after a couple of seconds or does it stay off until you recycle the unit? What kind of thermostat do you have, wall mounted or manual control? When say you start the air and it only humms and shuts off, does it trip a breaker, does the fan motor come on?

Fan won't run / won't cool


It may have a faulty compressor relay or overload, best to change both at the same time. It's either that or a bad compressor.

My pacr10 blows air but compressor wont kick on


sounds like a blockage in the refrigerant circuit, the compressor is shutting down, protecting itself. possibly the compressor is overheating, possibly it's overcharged.

check the cap for the fan. Will the fan start if you spin it when you hear the humming. Check the lock rotor amperage for the compressor to see if it is hung up. The cap if it is shared could knock out both the fan and comp so check both.

not sure if it is a package system or a split but this is what you do.go outside where your outdoor machine is, after it has been shut off for awhile, and you should hear 2 distinct noises.1 is the outdoor fan, you should see it spinning.the other is a comppressor hum.some compressors have noise bags on them so listen closely thru the fan noise.if you hear no hum listen for a hum about every 2 to 5 minutes.if you hear this hum every so often, chances are you compressor is seized or stuck.the only thing to do there is get a tech and try a big boost to get it going.

Compressor switches on but only humms fan does not spin


You have a bad run capacitor. You can change it or you can get a service tech to change it. About 150 for the job Rus

Hitachi EC12 Compressor- weird hum


The burst of air you hear as the compressor shuts off is the cylinder unloading so it will not have to restart against a high pressure load. If the unloader is electrical it would explain the hum that you hear. This could be a normal function.

AC keeps blowing fuses


Fuses are a protection device and I guess that this is for the condenser section and compressor. If they blow right now when it is turned on would indicate that there is a short in the wiring or motor or compressor. If it trys to start and the outside fan starts and the compressor just humms and blows fuse, you have a locked compressor. Might check run capacitor or install a hard start kit and see if it will brake it loose, if not bad compressor
