traveler2017 here is a thread that addressees the stat's on/off temps.

Richw46's discussion is in regards to a replacement stat and it's set points attached to the fins. Josephine517 refers to a 130 deg stat attached to the fan so not interchangeable. I'm not sure what the OEM set points are (on/off) but probably close to those in Rich's post #55.
On our 20 our refer switch is located by the door and behind that switch accessible from the top vent door is a fuse. I would check that first. If you have power there, test the stat attached to the fins (upper right hand corner of the compartment). You can jump it with a paperclip or otherwise and the fan should start instantly. You can also point a hairdryer on high on the stat and in a few minutes should come on.
Here is another read (IMO) post #6 that post contains a link with some pics of the stat and it's connections.

I'm suggesting this as from what I have read including all of Ray's OP ..."Refrig fan noise FIXED...really?" thread (
https://www.airforums.com/forums/f42...-11811-15.html ) ... Seems I recollect very few failed fans posts...most posts were swapping them out for greater efficiency, and noise reduction. I repurposed my OEM for my car sunroof when parked to help pull out warm air if the dog is with us.
The above fuse/stat tests will tell you what is or isn't working. However my suggestion is to spend $20 now and install a quality fan and be done with it. I bought a Silex as it has roller bearings. Super quiet and more efficient. Lots of good fans out there. I would also suggest getting a new quality stat as many posts indicate the failure of that part as well. Post 41 is where Rich ordered his and where I will order mine (inc a spare)
let us know if this helps.
