A/C fan always on

[nova73guy]

Just started last night. I have dual air conditioners on a Dometic digital control. The rear unit fan just started running constantly. It's set to auto, and the compressor isn't running with the fan. If I turn the power off it shuts off, but starts again with power on. Front unit is fine. Any insight would be appreciated.

Do you have the Dometic LCD multizone thermostat?
If so, you may be able to initialize it. Try the procedure below and see if that helps.

Turn off the thermostat and press and hold the zone and mode buttons simultaneously. This will reset your thermostat.

I tried resetting the thermostat with no luck. Fan still runs continuously, even when the set temperature is higher than indicated. As far as I can tell the indicated temperature is correct.

Edit: interesting development. I set the thermostat lower and let the unit run through a cycle, and it seems to be working properly. I tried that before, but it only worked after the reset.

Maybe resetting it did some good. Only time will tell. I hope that solved your problems.

I'm hoping it works. So far so good. Thanks for the help!
