replacement thermostat?

[BigB 23]

Now my A/C unit has a mind of its own. It shuts off for no reason, the fan will sometimes stop even though I have it in Man. lo/hi. And of course it stops most @ 2:00 in the AM. Does anyone know of a good thermostat to replace the little/frail digital P.O.S. Dometic one that's I have? I gues this is something else I have to replace in this brand new unit.
I have a 13.5k I believe in a 28dbs. It runs the heat/fan/ a/c. Thanks in advance.

Coleman/Mach thermostat? If all of the thermostat wires are not well connected, you will experience strange operation. Saw the same with mine. Unscrew from the wall and check the wire nuts on all wires.

I replaced my Coleman/Mach analog (slidewire) thermostat with the Coleman/Mach digital thermostat. Is a wire for wire change. Was well worth the cost as it now controls within 2 degrees. Was lucky to see the old slidewire thermostat control within 7-8 degrees.

I have a new dometic one that I will give you. I had trouble with my air a few years ago. The local dealer told me I needed a new thermostat. They had one that was an exact fit. I paid $35 for it. It didn't work. I needed the control board along with a new thermostat. That did the trick. So, I don't know if just a thermostat will solve your problem but you are welcome to what I have if you would like.
