Description

This defrost thermostat senses evaporator temperature and shuts off the defrost heater once the coil warms, preventing overheating. Replacing a failed thermostat restores proper defrosting to stop ice buildup and stabilize refrigerator temperatures.

• Controls the defrost heater based on evaporator coil temperature
• Closes when cold to allow defrost; opens as the coil warms to end the cycle
• Protects against overheating during defrost
• Failure may cause frost/ice on the back wall or evaporator, poor cooling, or a heater that never energizes

Includes: 1 defrost thermostat

• Disconnect power before service; evaporator fins and sheet metal are sharp
• Access the evaporator by removing the freezer rear panel; note wire routing and mounting
• Position the new thermostat in the same location for tight contact with the tubing; reconnect wires exactly as found
• Reassemble and monitor a defrost cycle to confirm heater operation

Testing tip: Most defrost thermostats show continuity when very cold and open when warmed—test while cold for an accurate reading.
