Scott Levy for Model Number Gsh25sgpass Hello. I have replaced the defrost heater and the limiter. After working good for about a month the coil is freezing up again. What have I missed or overlooked? Thank you
Answer Scott, Check for an air leak at the door seals and dispenser chute door. Check the evaporator thermistor resistance. Check to make sure the defrost drain pan is draining and the drain trough isn't blocked or full of ice. Usually, if the top portion of the evaporator is frosted or iced over, this would indicate an evaporator fan motor issue. If the evaporator is completely iced /frosted over check or replace the main control board on the back of the refrigerator. The main control board is also the adaptive defrost control circuit, which could also have failed. Read More... Answered by AppliancePartsPros.com | Thursday, December 28, 2017
