About the Defrost Thermostat
The defrost heater turns on several times throughout the day to melt away any frost that may have accumulated on the freezer evaporator coils. Before the defrost heater turns on, the defrost thermostat must sense that the evaporator coils are cold enough. If the coils are cold enough, the defrost thermostat will allow the defrost heater to turn on. (Usually, the temperature of the coils must be below 30 degrees Fahrenheit.) If the thermostat is defective, the defrost heater won’t turn on, causing the evaporator coils to frost over. To determine if the defrost thermostat is at fault, use a multimeter to test the thermostat for continuity. If the defrost thermostat does not have continuity, replace it.
