Is my thermostat faulty?
I recently picked up a 27’ 1994 Starcraft. The trailer had sat for a couple of years unused. I towed it and plugged it in…everything worked great. I then moved the trailer about 10 miles to where I...

I had a little time over last weekend. I cleaned out the entire trailer and found all of it's original documentation. The thermostat says Coleman Mach right on it and the manual for the AC unit also says Coleman Mach. Much of the weekend was spent cleaning out the old Aristocrat trailer and getting it ready to sell. I had previously always had the vintage trailer plugged into an outlet in the garage that it was parked next to. The shore cable never quite reached the outlet so I used an adapter and an outdoor extension cord.
My new trailer is now parked in the same location with the same situation...an adapter with an extension cord. I was unable to remove any wires from the back of the thermostat because they go under a circuit board without access. I would have to break it apart or cut the wires, so I left it for now.
Like I mentioned before, the furnace fan would not shut off as soon as the shore cable was plugged in. I switched the thermostat to heat and cranked the temp up to max. The gas was open. The furnace would click and but not ignite.
When I switched the thermostat to cool the furnace fan would continue to run. I turned the temp all the way down. I could hear the AC unit make a low buzzing noise but it would never kick on or blow air.
I had to physically remove the hot wire from the furnace fan motor to get it to shut off.
The AC unit on my newer trailer is larger and draws more than one in my old trailer. I am suspecting that the "draw" is too much for the extension cord that I am using and could be why it's not kicking in and only buzzing.
It will be a couple weeks before I get another chance to work on the problem. I plan to pick up an actual RV extension cable (heavy gauge) and see if this can remedy the problem.
