Woke up this morning and noticed both freezer and refrigerator side were not cooling at all. There is air blowing into the freezer section (but not cold). The compressor is not running (no noise whatsoever, no clicking) and the condenser fan is not running. Getting continuity on all 3 prongs of compressor. Loud humming noise coming from somewhere what seems to be behind freezer section. Any ideas what to check next?

Both compressor and condenser fans are powered from the main control board. If they are both not operating when the interior fan is, there may be a problem with that board or the P1 connector on that board may have come loose?

I'm not certain where located but it looks to be at the rear in the compressor compartment under this cover:




There are some diagnostic tests that can be done which are described in the unit's 'tech sheet'.

Inside the cabinet? If so, I don't know what would be in there to generate sound other than the evaporator fan motor. It shouldn't affect the operation of those other two components.

Thanks for your insight. I just got a new board and replaced it. The compressor now kicks on but the condenser fan does not, although I only had it on for about 15 minutes and decided to unplug it to prevent the compressor from overheating. Does the condenser fan get triggered to come on only after the compressor gets to a certain temp or does it run all the time the compressor is running?

Both components look to be on the same circuit in which case they should both run at exactly the same time. Maybe failure of the motor caused the board to fail in the first place?

Yep, there is current going to the motor so it's bad. Appreciate your help.
