Defrost Thermostat, Sensor

Fixes frost buildup in freezer or warm refrigerator temps caused by failed defrost cycles. This 55-degree thermostat restores proper defrosting.

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.

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 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.

This thermistor is a temperature-sensing component that monitors conditions inside the refrigerator or freezer compartment. It sends temperature readings to the main control board, which uses that data to regulate the compressor and defrost cycles. Replace this part if your refrigerator is running too warm, too cold, or cycling erratically despite correct thermostat settings.

Fixes refrigerator not cooling or excess frost buildup. This defrost thermostat regulates the defrost cycle. DIY-friendly repair, takes about 20 minutes.

Freezer working but fridge not cooling? Coils frozen solid? Replace your defrost thermostat. Mounts on evaporator to control defrost heater cycle.

Fix frost buildup and poor cooling in your refrigerator. This defrost thermostat prevents ice accumulation on the evaporator. Moderate DIY repair.
