GE refrigerator model gsh25kgrbww freezer is 20 degrees f, fresh food box is 55 degrees f. The motherboard, evap fan, thermistors, defrost t-stat, or all the above?
Answer Hello Stephen,
You need to check the back freezer wall for a frost build-up. If there is a frost build-up, you will need to open the rear wall of the freezer compartment and check the individual components. If the frost is only across the top of the evaporator coils, the issue will be the evaporator fan motor. If the frost is all over the evaporator coils, one of the defrost components have failed. The most common part to fail is the defrost heater WR51X10055. The defrost thermostat, thermistors, and main board are the remaining components in the circuit.
