coleman mach thermostat

Don't know if your trailer has ducted AC nor if your thermostat is one of the Coleman units that utilizes remote temp sensors. Anyway, make sure that the AC is not blowing directly at the thermostat or remote sensor whichever the case may be. When one of our AC ducts gets turned such that it blows on the remote sensor in our back bedroom it will act as you describe. Adjusting the duct direction solves the issue in our case.

I believe the Coleman thermostat has a 3 degree F swing and don't believe there is an adjustment. The residential digital ones have a 1 degree swing.

I took the junk Coleman thermostat out and replaced with a $20 non programmable battery powered digital thermostat, purchased it at Lowes. Much better and maintains consistent temps.

Is it even a programmable thermostat? I don't know of any Coleman Mach thermostats that are programmable.
