Lg Refrigerator LFC22740TT 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.

The Door Gasket is an OEM part for LG refrigerators. This gasket seals the refrigerator door, ensuring a tight closure to maintain the internal temperature and prevent cold air from escaping. By creating an airtight seal, the door gasket helps keep food fresh and reduces energy consumption.

You should replace the door gasket if it becomes worn or damaged. Causes of a bad door gasket can include wear and tear over time, damage from repeated opening and closing of the door, or warping due to temperature fluctuations.

Symptoms of a bad door gasket include:

• Warm spots inside the refrigerator
• Excessive condensation or frost buildup
• The refrigerator door not closing properly
• Increased energy bills

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

This Main PCB Power Control Board Assembly manages the appliance's electronic control and power distribution so cycles run as programmed and functions respond to user commands. Replacing a faulty board restores proper control operation. What it does:

• Regulates power to motors, valves, sensors and user interface circuitry
• Interprets control inputs and runs timed cycles and functions
• Helps prevent erratic behavior caused by failed board components
• Common symptom link: unit won't start, touchpad unresponsive, random resets or error codes indicating control faults

• Disconnect power before accessing electrical components to avoid shock
• Ground yourself and handle the PCB by edges to reduce static risk
• Inspect connectors and harnesses for damage; seat plugs fully during reassembly

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
