Heating and AC

[tomstandlee@gmail.com]

Can anyone explain why our AC comes on when we set the heater in cold weather? We were camping (not hooked up to outside power) this past week, outside temp 45, inside 61. We set the furnace temp for 73, Propane full open. The furnace blower came on and shortly thereafter heat as expected but the AC also came on. This had not happened prior to this. This was our first excursion out since buying the 2016 Pleasure Way Plateau LX.

Possibly your thermostat fan setting is "low" or "high" rather than "auto". The AC compressor is probably not starting, just the fan is running.

My 2021 Roadtrek Zion SRT did that too! I had to turn the thermostat off and on twice before it stopped.
