thanks, ***** ***** be a couple of things, it could be the fan motor itself, or the relay in the electronics that sends power to the motor. Are you able to do some testing?

First of all know that if the unit is new, and under warranty, you will void that warranty if you work on it, would you like to proceed?

I replaced the air-conditioner last week this RV we bought used and it was two years old but not use much the new AC work good for a couple of days but I noticedthat all of a sudden the fan Stopped but I could continue to hear a hum then fan would kick on.
