I replaced the motherboard thinking that was the problem about two weeks ago. I noticed that fridge is now starting to get warm on the top shelf and is working its way down. I imagine the coils are frozen like a block of ice again. Any ideas on what the problem can be? Thanks

Hi.

Open the evaporator and check if it's blocked with snow, don't guess. If it is - check the continuity of the defrost heater.
Heater open - replace it Part number: WR51X10055
Part number: WR51X10055


If the heater is good then most likely the defrost thermistor is bad Part number: WR55X10025
