So my vote is for a stuck fan relay. OP go upstairs, remove the AC cover and find the relay.

I think I have traced the problem down to the relay on the circuit board (which is accessible from in the coach)
Called Thor who said it was a Coleman warranty issue. I called Coleman who said the controller was handled by anothet group (RV Products).
I ended up with their tech support who confirmed my diagnosis and will replace the control board under the two year Coleman warranty.
Only issue is I need the serial number which is under the cover up top and it's raining today.
Once I get the serial number and replacement board it will take about 15 minutes to replace.
Worst case is I buy a new board on eBay ($75). Still better than a trip to CW.
