Dometic Thermostat Replacement - Stapleton42 - 04-16-2024

Does anybody have a working Dometic Duo Therm thermostat? One of mine went bad. Part number 3105356.004

Doesn't matter if it has heat option or not, my original heat system doesn't work and I don't plan to use it.

I would gladly replace the thermostat with a newer programmable one if there is a way to use one with the existing Dometic wiring but I have not found any cases of that being done with the search function.

Hey Mitchell. Send me a pic of that tstat and also a pic under the cover where wires attach. I just upgraded to a new tstat that just came out and I'm chatting wi the owner about if it will work for you.

Looks like a no go on my idea.

Unfortunately the old thermostats like this are not easily replaceable with a plug up replacement. In my case I abandoned the old thermostat and used the wiring and changed it over to a house style thermostat. This requires quite a bit of wiring with a new transformer and relays to make it all work. It’s not for someone who is not comfortable with wiring etc.

I got him covered. He’s getting one of mine for his coach.
