Description

This is the round bimetal defrost thermostat used in many refrigerators. It protects the evaporator from icing by opening and closing based on coil temperature, helping ensure consistent defrost cycles and reliable cooling performance.

• Monitors evaporator coil temperature to start/stop the defrost heater
• Opens on temperature rise to prevent overheating during defrost
• Can help if the freezer ices up, fresh food warms, or defrosts are inconsistent
• Often checked when the unit won't defrost or shows heavy frost on the evaporator

What's included: One defrost thermostat (wiring leads/connectors as shown by the manufacturer) Install notes:

• Unplug the refrigerator before servicing; defrost and access the evaporator area
• Mount thermostat to the evaporator tubing in the same location/orientation as original
• Use proper wire connections and route harness away from moving/hot parts
• After installation, verify defrost operation and check for air leaks or failed fans/heaters
