Lg Refrigerator LDC22720TT/02 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 Freezer Door Gasket is an OEM part for LG refrigerators. This gasket is designed to fit around the perimeter of the freezer door, creating an airtight seal that prevents warm air from entering and cold air from escaping. This ensures the freezer maintains a consistent temperature, which is essential for preserving food quality and reducing energy consumption.

Causes of a bad door gasket can include wear and tear from frequent use, exposure to harsh cleaning chemicals, or physical damage from sharp objects or accidental impacts.

Symptoms of a bad freezer door gasket include:

• The freezer door not closing properly
• Visible cracks, tears, or deformities in the gasket
• Frost or ice buildup inside the freezer
• Increased energy consumption due to the freezer working harder to maintain temperature

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

This door gasket assembly forms the airtight seal around your refrigerator door. Replacing a torn or warped gasket restores proper temperature control, reduces frost and condensation, and helps the unit run efficiently.

• Creates a tight seal between the door and cabinet to keep cold air in
• Helps maintain stable temperatures and humidity inside the compartment
• Reduces frost buildup and condensation around the door perimeter
• Common signs it's failing: gaps, tears, hard/warped rubber, condensation, or frequent cycling

• Disconnect power before starting; open the door for access
• Warm the new gasket with hot water or low heat to relax folds—do not overheat
• Remove the old gasket from the retainer/channel; clean the groove thoroughly
• Press the new gasket fully into the channel (loosen retainer screws if present), ensure corners seat, then perform a paper-slip test and allow time for the seal to set

This DC motor powers the appliance's cooling fan to move air across coils and through compartments. Replacing a weak or failed motor restores proper airflow for steadier temperatures and quieter, more efficient operation. What it does:

• Drives the fan that circulates air through the evaporator or across the condenser
• Helps maintain even cooling and prevent temperature swings
• Replaces a motor that won't start, runs intermittently, or makes grinding/squealing noises
• Can help address poor cooling, warm spots, or frost/ice buildup from lack of airflow

• 1 DC motor

• Disconnect power before servicing; wear cut-resistant gloves
• Access the fan area per service information (rear interior panel or machine compartment)
• Transfer the fan blade and any grommets/brackets/screws from the original motor if needed
• Seat the motor securely, route wires clear of the blade, and verify the fan spins freely before reassembly
