Fan motor will not shut off

[DGT2021]

The AC works fine with the compressor going on and off as should but the fan motor is constantly running. I have to flip the breaker to shut it off.
Any suggestions? Thank you in advance for this consideration.

Without more information it would be a "pin the tail on the donkey" to hazard a guess. How about some clues like model and year of camper, in command or wall t`stat, single a/c or multiple? All makes a difference. Go to user cp at top of page, click on edit, then enter the make, model, year of tow vehichle and trailer and then save. Then you have at least the basic info when you ask a question.

If it's a simple thermostat like mine it may simply be the fan switch is set to low or high and you want it in automatic. BTW, ALL airconditioners work more efficiantly with the fan running all the time on high speed. Cold air is dense so it takes more pressure to move and running the fan constantly distributes the air about the space more efficiently.

If you have iN·Command make sure the fan is set to auto..if you have the fan switch set to “off” then the fan will actually run all the time and compressor will cycle by thermostat…had that happen to me. The choices are fan “off,on, low and high” I believe..also will of course run all the time if set to “on low or high”

I set the fan to auto, and still the fan never shuts off. The breaker is how I am shutting it down until I find the solution. Thanks for the advice.

yes it is the incommand system. I have the fan set to auto. It never shuts off but the ac will cycle compressor on and off and will cool the rv. I am shutting down using the breaker until I find the solution. Thank you for the advise.
