Refrigerator Defrost Thermostat, Sensor

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.

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

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

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.
