GE Refrigerator defrost problem
My GE refrigerator Model GTS 22KMARBB purchased in 2002 has a defrost problem.
It has a main control board which controls both the compressor and the defrost heater.I have had the main control board and the defrost thermostat replaced but the problem persists, the evaporator coils freeze up every ten days or so.
The defrost heater gets very hot when a jumper is placed between the “line” and the “defrost” terminals on the control board.
The service technician says he has no other ideas on how to fix the problem.
What do you think? Could a thermistor be the source of the problem?
