Frigidaire Refrigerator Defrost Thermostat, Sensor

Fixes ice buildup and inconsistent cooling caused by defrost cycle failure. This thermostat senses evaporator temperature to control defrost timing.

Refrigerator not cooling or freezing over? This defrost thermostat monitors evaporator temperature to control defrost cycles. Easy DIY fix restores cooling.

This mechanical temperature control thermostat replaces the factory temperature sensing switch to restore proper refrigerator temperature regulation. It helps the appliance maintain set temperatures for safe food storage and normal cooling performance. What it does:

• Senses cabinet temperature and opens/closes the cooling circuit to regulate compressor run time.
• Commonly used when the refrigerator runs constantly or cycles too quickly.
• Works as the user-adjustable temperature control for manual-style refrigerator controls.

• Disconnect power to the appliance before starting any repair.
• Handle the sensing bulb/capillary tube gently; avoid kinks or sharp bends.
• Verify correct placement of the sensing bulb in the evaporator/probe clip per OEM location.

This thermostat monitors the evaporator coil temperature and signals the defrost heater to turn on or off during the defrost cycle. It prevents excessive frost buildup on the evaporator, which is essential for proper cooling in the refrigerator. Replace this part if you notice heavy frost accumulation on the back wall of the freezer, the refrigerator is not cooling properly, or the defrost cycle is not activating.

Fix a refrigerator that won't cool or frosts excessively with this defrost thermostat. Senses temperature to control the defrost cycle properly.

This is a bimetal thermostat mounted on the ice maker mold that senses temperature to control the ice harvest cycle. It signals the ice maker to begin the harvest and eject ice once the mold reaches the proper temperature. Replace this thermostat if the ice maker stops producing ice, runs continuously without ejecting cubes, or if ice cubes are only partially frozen.

This thermal cutoff is a safety device in the refrigerator's ice maker that shuts off the heater circuit if temperatures exceed safe limits. It helps protect the ice maker assembly from overheating during the harvest cycle. Replace this part if the ice maker stops producing ice, fails to complete its cycle, or if testing confirms the thermal cutoff has tripped and no longer resets.
