Nick for Model Number PFSS6PKXDSS Evaporator ices up in two months in the refrigerator section what needs to be replaced and does it have a defrost timer?
Answer Hello Nick, first access the ref evap coil and check if the defrost thermistor is still secure to the coil tubing, if not correct it as needed, it has to be making good contact with the tubing. If it is secure to the tubing, replace it with part WR23X10582 defrost thermistor. If the problem continues then replace the main control board. Your model does not use a defrost timer, defrost operation is through the main control board. Read More... Answered by AppliancePartsPros.com | Thursday, May 13, 2021
