Refrigerator Defrost Thermostat, Sensor

Refrigerator not cooling or frosting up? This defrost thermostat controls when the defrost heater turns off, preventing ice buildup on evaporator coils.

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

Freezer not cooling or frosting over? This defrost thermostat monitors temperature and controls the defrost cycle to prevent ice buildup and restore airflow.

This evaporator wire harness delivers power and control signals to the evaporator fan and defrost components. Replace a damaged harness to restore stable cooling and dependable automatic defrost performance. What it does:

• Provides plug-in electrical connections for evaporator-compartment components
• Carries power and control signals for cooling and defrost cycles
• Enables proper airflow across the evaporator and effective frost removal
• Common clues of a failing harness: heavy frost on the back wall, evaporator fan not running, intermittent cooling, or burned/brittle wires or connectors

• 1 evaporator wire harness assembly

• Disconnect power to the refrigerator before servicing
• Access the harness behind the freezer/evaporator cover; remove drawers/shelves and the rear panel
• If iced over, allow ice to melt—do not use sharp tools on coils or wiring
• Route and secure the new harness exactly like the original; fully seat each connector

Fix inaccurate cooling or temperature fluctuations in your refrigerator's fresh food section. This sensor monitors compartment temperature for the control board.

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

Fix refrigerator frost buildup or warm temperatures with this defrost thermostat sensor. Moderately easy repair for most home DIYers with basic tools.

Refrigerator not cooling properly or freezing over? This defrost thermostat regulates defrost cycles to prevent ice buildup. Moderate DIY repair.

The Temperature Sensor is an OEM part for LG refrigerators. Also known as a thermistor, is responsible for sensing the temperature changes and providing the necessary feedback to the refrigerator's control board. It helps maintain accurate and consistent temperature levels, ensuring optimal food preservation and efficient cooling.

Causes of a faulty temperature sensor can include wear and tear over time, damage due to electrical issues or exposure to extreme temperatures, or sensor calibration issues. These factors can result in temperature inconsistencies, inaccurate readings, or improper cooling performance of the refrigerator.

Symptoms of a bad temperature sensor may include:

• Incorrect temperature readings on the control panel
• Temperature fluctuations inside the refrigerator
• Overcooling or inadequate cooling of food items

This OEM LG part can also be used on Kenmore/Sears appliances. 

Fix ice buildup on evaporator coils or freezer not defrosting properly. This defrost thermostat monitors temperature to prevent frost. 2-hour repair.

This freezer wire harness links the refrigerator's control system to components inside the freezer compartment. Replacing a compromised harness restores reliable electrical connections and can resolve intermittent or dead freezer functions caused by burned, broken, or corroded wiring.

• Routes power and signals between the control system and freezer components
• Supports proper operation of devices such as the evaporator fan, defrost circuit, lighting, or icemaker
• Replaces cut, heat-damaged, or brittle wiring and loose/oxidized connectors
• Typical symptoms: intermittent cooling, components not running, or visible burned/melted connectors

• Disconnect power to the refrigerator before servicing
• Photograph routing and connections; move wires over one-by-one to the new harness
• Seat connectors fully until locking tabs engage; avoid forcing pins
• Route through original clips/grommets and keep clear of sharp edges, hot surfaces, and moving parts

Fixes frost buildup on evaporator coils and inconsistent cooling. This bi-metal thermostat monitors temperature and controls defrost heater cycles.

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.
