G.E. brings good things to light. G.E. went to a control board which you can see in the back of the frig behind a panel maybe 6x8 inch. The board controls everything from DC fans, to defrost heaters to compressor. Every major supply warehouse has a 100 plus boards in stock because they go bad alot. If you call G.E. tech support (which you can't unless your on the bubba list) they will tell you to check a couple things and replace board and fan motor. BTW this happened to my frig on Thanksgiving day I stuck a free standing fan in back of my frig to get me by till I could get parts. It was the circuit board that was bad which is the case 9 out of 10 times. Does no DIY count on appliances ?
Insanity: Doing the same thing over and over again expecting a different outcome!
