AC Issue Using Auto Position

Question: I have a coleman mach 1 ac on top of RV.It cools fine but will not work in auto mod on wall thermostate.Some times it will kick on in auto but once it kicks off thats it till i put in the on position on the thermostate.It kools fine and seems to work properly other than in auto position

Robbie: The thermostat turns the AC unit on and off if when it shuts off the AC doesn't come back on then the thermostat is not sending a signal. Make sure all connections are tight and clean and replace the thermostat. I think this will solve your problem.

Thanks for the Question Good Luck,
