I have a failed defrost system on this refrigerator. I was wanting to check the defrost heater and defrost thermostat. The tech sheet that is supplied with the refrigerator in the cover on the botton of the refrigerator is missing. How do you initiate the defrost cycle with this electronic timer?
Answer John, There are two procedures, The defrost thermostat has to be closed( freezer has to be cold) Option #1 1. Power off to refrigerator for t least 30 seconds. 2. Thermostat off 3. power on to refrigerator. Option #2 1. Thermostat off for 15 seconds 2. Thermostat on for 5 seconds.(Repaeat steps 1 and 2 Two more times) 3.Thermostat off. In 3 to 8 seconds the control will turn on the defrost heater for 21 minutes, or until the defrost thermostat opens. Try both options before replacing control
