Dometic thermostat

[destination.brewing]

I have a 2018 White Hawk, the dometic t thermostat had started turning on the AC at least the fan when heat is turned on. Any ideas why? Have tried different fan settings, low, high, auto.

Dest,

Any chance you can post a picture or provide the model number of the thermostat?

Separate the heat and ac on the thermostat by 10 degrees or more. I had this problem on a 2015 TT.

Problem solved, my wife did just as you said on her own and it works fine.... User error.

I had the same thing happen to me. Put the fan setting on "auto" when running the furnace rather than "high" or "low". On auto only the furnace fan will operation while running the furnace.
