unreliable thermostats?

am I the only one who cannot trust the dometic thermostats that came with my 2018 Montana. Living area and bedroom each have one. Neither is reliable. Both will jump from cool to heat for no apparent reason. Usually when i am turning them on. I usually wait to make sure the setting takes and then usually it is OK. But every now and then they just decide to change themselves. If i am not the only one, what have you guys done? Has Dometic made some improvements since 2018?

All three of ours have been fine although a little touchy. Others have had issues and called Dometic and Dometic has sent some of them new thermostats. I would call Dometic and see what they will do for you.

It is a well known problem. Call Dometic, they will replace them. I had one replaced under warranty and it now works fine. The other is starting to act up and I will have that one replaced as well.
