Question and Answers

Q:

My Kenmore refridgerator is no longer automatically defrosting, is there a part we can replace ourselves, or do I have to call for service?

A:

There could be one of several possible failures preventing your Kenmore refrigerator from automatically defrosting.

  • Defrost timer
  • Defrost heater
  • Defrost termination switch

Most likely the failure is a burnt out defrost heater however it could have a failed defrost timer or defrost termination switch. Remove the rear panel from inside the freezer and look at the heater inside the glass tube and if the inside of the tube is blackened then the heater is likely burnt out. I believe the replacement heater will be a Calrod type heater and not a heater in a glass tube. If the there are no signs of the heater being blackened then the failure will need to be diagnosed by placing the defrost timer into defrost and checking the voltage supply to the heater. NOTE: I do not recommend checking voltages unless you have experience and you feel safe and confident in doing so, otherwise I recommend calling a service technician. The defrost timer is located in the control box inside the refrigerator section where the cold controls are located. The defrost timer can be advanced manually into defrost by turning the stem clockwise until the fans and compressor turns off. Note: I do not recommend turning the defrost timer manually unless you are very careful and not touch or short any wire connections or you could become electrocuted. I recommend calling a service technician to diagnose and repair your refrigerator. The defrost heater is part #WR51X465 at $96.49 which can be ordered and shipped to you from Sears Parts Direct . If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website: Sears Home Services .
