HELP--Replace a Dometic "soft touch" thermostat????

We took our 2018 Bullett 248RKS out for its 1st rip with us.
all went well but... The PO told me the thermostat was possessed. He was right. the thing would change temp, mode or turn off just by waking by it, I would love to replace it with a more conventional style but am being told it cant be done. The A/C on the roof has some kind of control board that requires this thermostat. Any input??

You were told exactly what Dometic told me. I am assuming you have the "capacitive touch" thermostat. I went through 4 of them. Seems (per Dometic) that had a "bad batch" of them sometime around 2018, and yes, they are possessed. Contact Dometic, explain the situation and see if they won't send you one free of charge. They sent me one but after I had already purchased 3 (about $40 if I recall).

One thing that I tried is to pull the cover off and there are little bits of foam inside the cover where the contacts slip into it. Pop them out and turn them around and lightly press them back in, then reinstall the cover. It improved the performance of mine, but no guarantees.

I have the capacitive touch and don't like it. It is not a well designed device. I've been wondering if it could be replaced with a conventional digital stat.

Mine works okay, I just don't like the thing. I have read many comments where people contact Dometic and get a free replacement so you have a good chance at getting one.

I took those foam inserts and moved them, turned them over, modified their lengths etc. They are just junk. Unfortunately that is what Dometic is making and what Keystone is buying. I will say after I got some (one?) from a new batch it did not fail. This new trailer has them and so far they operate pretty well. Not sure they can actually tell the temp (I have multiple thermometers in the RV) but sort of close....at times.

The Dometic thermostats use CANBUS channel to communicate back and forth between roof mounted AC unit and furnace. The link between thermostat and AC/Furnace is the control module... gateway

I have exchanged emails with Shelley at Dometic. I assume she is sending a new faceplate since she ask what color mine cover was and for an actual shipping address. I will report back!

Which thermostat are you asking about? The A/C-furnace thermostat, the water heater thermostat, the oven thermostat or the refrigerator thermostat?

Not trying to be a "wise-a**" just wondering, if you've purchased the trailer and done the PDI, didn't the dealership orient you to how to use the equipment? If you've forgotten, what help do you need?

If the trailer is 18 months old, then the model year is a 2018 or 2019 ?? If so there is no adjustable thermostat on the water heater.

If you have a conventional thermostat, it will be mounted on the wall, probably near the center of the trailer (front to back) and about chest high. It will look something like one of these photos. There are settings for A/C, Heat/furn and Fan. It scrolls through with the UP/DOWN buttons on both sides of the LCD screen

I don't believe you have the InCommand system, but if you do, there is a different process.

Oraven, I have watched 3 walk thru videos trying to determine the location of your thermostat. Not knowing year etc. here is a link the model trailer you have. At the 3:54 mark I believe I see the AC/furnace thermostat behind the salesman's shoulder on the wall...I hope.

Is this the thermostat that you're saying has the problems (or had). Reason I ask is that the DW would like to look at a wall or exterior cabinet panel to change the setting rather than look up (she's had several surgeries on her neck and spine)

That appears to be the Dometic capacitive discharge thermostat that I've had so much trouble with.

Ok, thanks. We’ll steer clear of it.

Depending on the control box interface in the air conditioner (which also controls the furnace) you may not be able to 'steer clear of that type thermostat". Do your homework before spending a lot of money on a replacement that won't work with your HVAC system. Many places will not allow a return of "used electrical equipment".

As John mentioned, steering clear may not be an option. When trying to get a thermostat that would actually work, and get rid of the Dometic CT unit, I was told by Dometic it was the only one that would work with my AC unit.... So, do your homework before just buying something in the hopes that it will work.

Understood. I’m looking to possibly change roof units and by having a thermostat on the wall it makes the adjustment of the temps easier for the DW. We’ve gotten along without one for this long, we may just stick with the ceiling type controls.

I've always had really good luck with Dometic ACs and like them. They lost their way with the CT thermostat and it is just a bad design IMO. If you replace the unit try to see what options there are if you have a different control module for a different thermostat installed. Don't know if there is such a thing...or maybe a Coleman if you're going replacement. Didn't really like their units years ago but haven't had one in a long time. I also haven't read constantly of thermostat failures with them. Just something to think about - and yes, a wall thermostat is more convenient and more accurate IMO.
