Dometic thermostat will not work with the faceplate on.

I can make our thermostat work just fine with the plate off. even going from Degrees C to F

The second the cover is put back on it goes from AC fan high to furnace.
The buttons do not work when the faceplate is in place. The kicker is, both of them are acting the same.

I had the problem when I took the faceplate off of one of mine. Took several tries, but finally got it to work right again. As I remeber it, I finally gently pushed the little sponge things back and after a couple of tries got the cover back on carefully and vowed never to take the cover off of them again.

This has been an issue for a while. Dometic knows it and they are replacing the faceplate (the source of the problem). Take a look HERE and look at Posts #37, 38, 41, and then, the money shot, #44.

Okay. did not call Dometic. Tried the contact us link on web page. I told them Carl sent me. Hey this way I did not have to listen to HOLD music.

Without batting an eye, they requested address to ship new ones.

Thanks

Well I got my package from Dometic. The box they sent me contained teh whole mounting kit for one unit. I needed 2 faceplates. So not quite there yet.

added twist.

When I brought it home from storage the touch pads worked fine. I think disconnecting 12VDC cleared the error.

I did not try the new faceplate yet. Going with if it ain't broke don't fix it. Especially this close to hitting the road.

Yeah, I got my package from Dometic on Tuesday and it was also a full kit. I popped the new faceplate on and it works like a charm.

This was the easiest process ever. I mailed them from the contact page on their site and they shipped me the unit the next day. Excellent customer service.

I had a very different experience with calling dometic customer service. They told me to remove faceplate for 20 minutes and then reset thermostat. Guess I'll give the email option a shot.

That's lame.

Here's the exact text I put on their email communication form on the website:

I have a new 2018 Montana 3950BR. The bedroom thermostat is a Dometic CT type. It seems to only work correctly when I use it with the faceplate off. Reading the Montana Owners forums, it sounds like this is a known issue. I'm hoping I can get a corrected faceplate without having to hassle with taking my full-time unit into the dealer. Can you help?
The next day the mailed me asking for the color of my thermostat and my shipping info. 5 days later (including a weekend) I had it in hand.

Hope you have similar results.

Thanks Bierp, worked like a charm. Two faceplates on the way.

Dometic promised to send me two replacement faceplates but never did. Plus the customer service lady was not nice at all.

Not sure what your model your RV is - but this is the Dometic thermostat on Amazon for most recent models. When my unit was maybe 2 years old Dometic sent me 2 new thermostats. Those did not work for long and I replaced them with the MicroAir below.
The 2nd screen shot is expensive but it will be the last thermostat you will buy. Sometimes they run a sale with maybe 20% off - and that is when I bought my theremostats.
