The defrost timer (Key 257 in the image below) is in the control housing (Key 436) that is located in the roof of the fresh food (refrigerator) section. The normal method of determining the failed component in the automatic defrost system is to manually advance the defrost timer with the compressor running until the compressor kicks off to indicate that the refrigerator is in the defrost mode. You should find a hole in the control housing where you can access the defrost timer. Use a small flat tip screw driver to manually advance the defrost timer (while the compressor is running). The compressor will likely be running or you can hold the refrigerator door open long enough until it starts. Once the compressors stops, check the defrost heater on the evaporator to see if it is heating. If it is then the defrost timer is your likely failure. If the defrost heater is not working, your likely failure is the heater or the defrost thermostat. (You could also have a wiring failure or you could still have a bad defrost thermostat if a contact is bad in the thermostat.) If you are able to unplug the refrigerator and then bypass the defrost thermostat by taping the wires going to that component together with electrical tape, you can determine whether a failed heater or a bad defrost thermostat is causing your problem. (NOTE: Do not allow the heater to stay on for longer than it takes to determine that it is heating properly. Overheating the evaporator can cause damage. Do not continue to operate the refrigerator with the defrost thermostat bypassed.) If the heater won't work with the defrost thermostat bypassed then your likely failure is the heater. There is a kit (part WR51X443) that includes a new heater assembly, a defrost thermostat and the wire harness. You can order that part (or other parts if needed) from the Sears PartsDirect website.

These tips should help you determine the likely cause of your failure. If you need more help, submit more details and we will assist you further.

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 .
