Top two evaporator coils don't ice up but the lower ones do
I have a GE GSH 25 KGPA side by side freezer. It started acting up (refrigerator getting warm) a couple of weeks ago. On investigation, I discovered the thermostat was bad and replaced it with a new one (different model number than the original as the original is no longer manufactured but the GE site indicated the one I ordered is compatible). I kept the freezer wall panel off to make sure I could keep an eye on the evaporator coils....they are freezing up again EXCEPT for the top two which aren't. Does anyone have any experience with this and can you advise me as to what to do next? Thank you!!!
