Frigidaire 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.

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

The Thermistor is an OEM Replacement Part that maintains the temperature inside your Frigidaire refrigerator. This thermistor handles reading the internal temperature. After reading, it transmits this information to the control system. At a temperature of 29 degrees, the thermistor should exhibit a resistance of about 35k ohms. While at room temperature, it should read approximately 5k ohms.

Causes of a bad thermistor can include regular wear and tear, exposure to moisture, or electrical issues. Over time, the thermistor may become less accurate or stop working altogether.

Symptoms of a bad thermistor include:

• Inconsistent or incorrect temperature readings
• The refrigerator being too warm or too cold
• The cooling system running continuously or not at all
• Error codes related to temperature control

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.

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 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.

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.
