Description

This bi-metal defrost thermostat controls the refrigerator's defrost cycle by opening or closing the circuit to the defrost heater, helping remove frost buildup and protect the heater from overheating. What it does:

• Opens the defrost heater circuit when the evaporator reaches the correct temperature to stop heating
• Closes the circuit at colder temperatures so the heater can run during a defrost cycle
• Helps prevent excessive frost buildup that can reduce cooling performance
• Commonly replaced when the defrost cycle fails to start or will not end properly

What's included:

• One defrost bi-metal thermostat

Install notes:

• Disconnect power to the appliance before servicing to avoid electrical shock
• Located near the evaporator/heater assembly; access may require removing panels or the evaporator cover
• Handle carefully to avoid bending terminals or damaging the sensor element
• Test for continuity before replacement
