SOURCE: Compressor will not come on. Fan runs great.

I fixed it. I had a dirty connection on the starter relay for the compressor. Thanks again for the help.

SOURCE: 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.

Coleman mach chill grill - heat turns on whether we have it programed or not. have heat off, ''I feel'' off, can be 80 outside we can be gone and come back to 110 degrees inside and heater on. When it...


Sounds like you have a bad thermostat or a short in the wiring. The clicking that you are hearing in the ceiling is a relay in the control board. When this happens, remove the face plate from the thermostat and check for 12VDC between the Blue and the White wires. If there is power then you have a bad thermostat. If there is not power there, then the problem is elsewhere. However, it sounds as if you have a bad thermostat.
