Question about Coleman Mach 15 Air Conditioner
Need to re-charge the system
Posted on Apr 25, 2009
Have a Coleman roof top unit, unit starts when off a while, runs great until temp control tells compressor to turn off, after temp control tells compressor to turn back on, it dims lighting, doesn't start back on and trips breaker after a 15 second period. If I reset breaker and wait awhile, then try it again, sometimes it will start. Once running, if I leave temp control high and unit runs - it doesn't have any trouble until I turn temp control to a high temo setting, then it trips the breaker after trying to restart.

This is a typical symptom of having an A/C system low on freon if it cycles on and off when first turned on or very soon afterward. All types of A/C units for home and auto have a low pressure cut-out switch that will disengage the compressor when the freon level drops low enough to cause damage to the compressor. The unit needs recharging with the proper amount of freon to correct the problem. If it's an automobile A/C system and the freon level is okay, it could be a faulty compressor clutch or coil.
