SPECIFICATIONS The 215846602 Refrigerator Defrost Timer are part of the defrost circuit in your refrigerator and freezer. This timer cycles the defrost heater on and off. For every eight hours, the appliance timer will cycle for 30 minutes. The defrost heater is what melts the frost buildup on the evaporator coils, and it can prevent your freezer from frosting up. If your timer fails, the heater will not get the energy it needs to run, and frost will continue to build up. Test the defrost thermostat and the defrost heater with a multi-meter. If they are in working order it is likely that the defrost timer is the faulty component of the circuit and needs to be replaced. Before you begin this repair make sure the appliance has been unplugged.
