How to put GE in diagnostic mode
This bottom freezer GE I bought in 2015. How can I put it in diagnostic mode? Model# is PWE23KSDESS.
Freezer is working, but was too cold at -16 degrees. Fresh food compartment not cooling, was about 65 degrees. I did some disassembling and found coils just on top of freezer but behind lower part of fresh food compartment are covered with ice. Also found a fan there. I suspect that fan is not working. Blades spin freely, but when I close doors on fridge I don't hear it kick on. There is another smaller fan that sits right nearcthe water reservoir . I think its to cool the water. I did not see thatone turn on either. I do see the fan in freezer turning. It turns even when I have freezer door pulled open. I'm curious if that is normal operating since for fresh food compartment, fan is supposed to turn off when you open doors. So I'm not sure if freezer fan is supposed to run when freezer is open .
Now about 12 hours after clearing ice, freezer at 0 degrees, and fresh food at 63.
So I want to put it in diagnostic mode to see if maybe other issues like defroster, bi metal, etc.. is messed up. The plug on the fresh food fan is those 6 prong ones. Not sure how to test? Please any help greatly appreciate.
