Heat pump/AC blower runs continuously

Blower runs continuously even after reaching target heat or cool temperature. Can hear compressor cycle on/off but blower continues to run. Has a Dometic thermostat with fan speeds of either hi or lo, no auto setting. Anyone out there have a solution for this issue? Currently traveling to B.C. and Alberta campgrounds so WiFi is very spotty or nonexistent.

Are you sure you don't have an auto setting? Encountered a similar issue on our shakedown where we had to wake up, turn on the heat, then turn it off to get some rest after it warmed up. Next morning discovered the auto setting...but at least we found it. Just keep cycling through after you choose either "cool", "furnace", or "heat pump". Then you can choose "high", "low", or "auto". If you truly don't have an "auto" setting then you should expect the outcome you're experiencing where it's either on or off.

For what it's worth we also have the Dometic thermostat on a 2016 W. If you have any of the newer MBS's (R/S/W) I'd be shocked if you didn't have an "auto" setting.

Ours had a similar problem but the thermostat has a heat/cool auto and fan. To turn off you had to cycle through those and it looked like it was off but it was really on fan. Rv dealer had to show us.
