Lg Refrigerator LBC20514TT Doesn't shut off

The Defrost Sensor Assembly is an OEM part for LG refrigerators. It plays a critical role in the defrost system by monitoring the temperature of the evaporator coil to ensure that it remains at the optimal temperature to prevent frost buildup. The sensor sends signals to the control board, triggering the defrost cycle when necessary.

Over time, the defrost sensor assembly can fail due to wear and tear, electrical issues, or exposure to moisture and temperature fluctuations. When the defrost sensor malfunctions, it can cause improper defrost cycles, leading to excessive frost buildup, reduced cooling efficiency, or the refrigerator not defrosting at all.

Symptoms of a bad defrost sensor assembly include:

• Excessive frost buildup on the evaporator coils
• Refrigerator or freezer not maintaining the correct temperature
• Increased energy consumption
• Refrigerator not defrosting properly

This OEM LG part is also compatible with Sears/Kenmore.

This condenser fan motor spins the cooling fan that draws air across the condenser coils and around the compressor. Replacing a weak or seized motor restores proper heat removal so the refrigerator can hold temperature and run more efficiently. What it does:

• Drives the condenser fan to move air through the rear condenser/compressor compartment
• Helps dissipate heat from the refrigerant and protects the compressor from overheating
• Supports stable internal temperatures and efficient cooling performance
• Common symptoms: fan not running, louder rattling/grinding at the back-bottom, hot cabinet sides, warmer-than-normal refrigerator temperatures

• Includes 1 cooling fan motor

• Disconnect power before servicing; pull the unit away from the wall for access
• Remove the rear lower access panel to reach the condenser fan area
• Note wiring and fan-blade orientation; transfer the blade and any mounting hardware from the old motor as needed
• The fan spins freely and airflow direction matches the original before reassembly
