Try changing out the start up and run capacitors for the compressor.

The unit is not cooling. The fan works, the Compressor turns on but after a few seconds shuts off.


Hi,
The compressor is not always starting...sometimes it tries but does not start...
It could be a capacitor and relay problem... or the compressor could be going bad...
Change the capacitor and start relay first and then see if that gets it going...

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.

Coleman Mach 15 AC just quit. no compressor sound, no fan


If this is a ducted unit, check the thermostat. It has a fuse for protection that may have blown. If the fuse is fine and you have power to the upper units control box, check for 120V incoming power at the control box and also check for incoming 12V on the Yellow and GH wires when tstat is set to high cool.

Hope this helps.
