Refrigerator Defrost Thermostat, Sensor

The Wire Harness is an OEM part for Frigidaire refrigerators. It connects various electrical components within the refrigerator, ensuring proper communication and voltage.

A bad wire harness can be caused by wear and tear, damage, or electrical issues. When the harness becomes faulty, it can result in issues such as intermittent or complete loss of power, malfunctioning controls, or improper functioning of the refrigerator's features.

Symptoms of a bad wire harness include:

• Loss of power to the refrigerator or specific components
• Inconsistent or erratic operation of controls or displays
• Malfunctioning lights, fans, or other electrical features

Replace your faulty wire harness with this genuine OEM part to restore your refrigerator. This Frigidaire part can also be used on Electrolux, Frigidaire, Gibson, Kelvinator, Westinghouse, and Sears/Kenmore.
 

This is a thermostat that monitors the temperature in the ice maker to signal when ice has fully frozen and is ready to be harvested. It acts as a thermal cutoff device to regulate the ice-making cycle. Replace this thermostat if the ice maker stops producing ice, runs continuously without cycling, or fails to eject ice at the proper time.

This temperature sensor (thermistor) detects internal appliance temperature and sends readings to the control board so the unit maintains proper cooling. Replacing a failing sensor restores accurate temperature monitoring and helps prevent spoilage. What it does:

• Measures internal temperature and provides a resistance-based signal to the control board
• Helps the control system regulate compressor and defrost cycles
• Commonly causes warm or fluctuating temperatures, prolonged cooling, or temperature-related error codes when failing
• Works as a direct-sensing temperature input — not a user control or switch

• One temperature sensor/thermistor (single part as shown)

• Unplug the appliance or switch off power at the breaker before servicing
• Handle the sensor and its thin leads carefully to avoid damage during removal and installation
• Route and secure wiring so it does not contact moving parts or sharp edges

Fix ice maker frost buildup with this refrigerator defrost cable. Connects ice maker to defrost system to melt frost and maintain ice production.

This defrost thermostat helps control the refrigerator/freezer defrost cycle by sensing evaporator temperature and allowing the heater to run when frost removal is needed. Replaces a failed thermostat to restore normal defrost operation. What it does:

• Closes when the evaporator is cold so the defrost heater can run, then opens when the coil warms to stop defrosting
• Helps prevent excessive frost and ice buildup on the evaporator coil
• Common symptom: visible frost or ice on evaporator, excessive frost buildup, or defrost heater running constantly/ not at all
• Works with the defrost system to maintain efficient cooling performance

• One defrost thermostat

• Disconnect power to the appliance before starting any repair
• Mount on or near the evaporator coil as originally installed; secure wiring away from moving parts
• Inspect the harness and connector for damage; replace if corroded or brittle
• Test for continuity with a multimeter to confirm thermostat function before and after installation

This flow meter measures the volume of water passing through the refrigerator's water dispensing system. It sends signals to the control board to accurately track water usage and control dispenser operation. Replace this part if your water dispenser delivers inconsistent amounts of water, fails to shut off properly, or if the dispenser display shows inaccurate readings.

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.

Fixes frost buildup in freezer or refrigerator running too cold. This defrost thermostat regulates defrost cycles to prevent ice accumulation. Easy repair.

This bi-metal defrost thermostat monitors the evaporator temperature and signals the defrost heater to turn on or off during the defrost cycle. It acts as a safety device to prevent the evaporator from overheating. Replace this part if your refrigerator is building up excessive frost on the back wall, not cooling properly, or running constantly due to a failed defrost cycle.

Fridge not cooling but freezer works? This defrost thermostat monitors evaporator temperature to prevent frost buildup. Tests closed when cold with multimeter.

Fixes inconsistent cooling or frost buildup caused by faulty temperature sensing. This refrigerator defrost thermostat restores accurate readings.

This is an electrical connector strip used inside the refrigerator to join wiring harnesses or connect components on the control board. It ensures a secure electrical connection between circuits. Replace this connector if you notice intermittent power issues, error codes, or if the strip shows signs of burning, corrosion, or damaged pins.

Fixes refrigerator not cooling or freezer icing up issues. This defrost thermostat regulates defrost cycles to prevent frost buildup. Basic repair.
