Hi,
When the compressor starts you will hear the unmistakable noise associated with it...there is a definite hum from the compressor...check the t-stat on the unit... they often go bad..

Not cooling


check the and see if the condenser fan is running. you will find it if you take the top off also check and see if the condenser coil is clean. if it is dirty or the fan under the top is not running it will cause the compressor to short cycle on limits or overload.

My coleman mah 3 roof top will not blowon fan side


Sounds like you have either a bad fan motor or a bad fan motor capacitor. When you turn the unit on with the fan not working, the compressor (the humming noise) runs and gets real hot real quick resulting in the compressor cutting off ( the nothing after) on it's inside high temp switch. This is what the compressor is designed to do so that when this happens, it does not burn the compressor out. Replace you fan capacitor, give the compressor an hour to cool, then try it. In most cases and if I'm correct, the unit will run just like you want it to. Good luck.

We have a 2000 Coleman Cheyenne pop up with a Coleman mach roof unit. We turned it on today at home and the fan blows but the heater doesn't heat up and the air conditioner doesn't cool. Someone said if...


The distance of the cord is a big deal, 10AWG Cord would be best for this situation. If you have a 50ft cord, make sure that the cord is not wound up on top itself as this can cause a drop in voltage and a spike in amperage. Is the compressor trying to come on at all? If not, then you may have a problem with the selector switch or the thermostat. If the compressor is humming for a few seconds and then stopping and then trying to come on again, it could be a problem with voltage loss. Anything below 98.5 plus or minus 10% is too low the for the compressor to kick on.

I have a Coleman 6770 A Series roof air on my trailer. It won't blow cool air. Is this a compressor problem? And if so, would it just be cheaper to replace the whole unit than to try and repair this one?


Before the compressor is condemned, is it running at all? Is it getting the proper voltage? If the compressor will run and still does not cool the system could be low on refrigerant.

A replacement compressor is normally more economical than replacing the entire unit. It could be something as simple as a open thermostatic control.
