Lg Refrigerator LRFD22850ST 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 refrigerator door gasket creates an airtight seal between the door and cabinet to keep cold air in and moisture out. Replace a worn or torn seal to restore cooling performance, reduce frost, and prevent temperature fluctuations.

• Forms a continuous seal around the door perimeter to minimize air leaks
• Helps maintain proper temperatures and humidity inside the refrigerator
• Common failure signs: gaps, tears, or hardened/warped corners
• Symptoms may include doors not closing flush, condensation or frost buildup, and longer run times

What's included: 1 door gasket assembly Installation notes:

• Unplug the refrigerator before servicing
• Warm the new gasket in hot water or with a hair dryer on low to improve flexibility
• Pull the old gasket from the retainer channel; press the new gasket into the channel, starting at the corners
• Close the door and check for uniform contact all around; re-seat and adjust as needed

Main control board assembly that manages power distribution and electronic controls for the appliance, helping restore normal operation. Replacing a failed board can fix unresponsive controls, random cycles, error codes, or machines that won't start. What it does:

• Routes power and control signals to motors, valves, heaters and user interface components to coordinate appliance functions.
• A failed board can cause the unit to be dead, have unresponsive or erratic controls, or start/stop mid-cycle.
• Use diagnostics to confirm the board is at fault before replacing; mechanical or sensor failures can produce similar symptoms.

• Disconnect power at the breaker or unplug the appliance before starting any work.
• Handle the board by the edges and use anti-static precautions to avoid damaging electronic components.
• Photograph or label each connector and wire before removal for accurate reassembly.

This is an LG primary control board display assembly for refrigerators. The main function of this component is to control the display screen on the front of the refrigerator and control its main roles.When the refrigerator's main display on the front of the appliance malfunctions and doesn't display properly, the main issue is most likely the PCB display assembly. This allows a user to control several other functions of the refrigerator, including temperature setting, defrost, and ice maker settings. These malfunctions can be remedied by installing a new PCB display assembly. Always unplug the appliance before making any repairs. Wear gloves if possible.This product is a genuine OEM part sourced directly from the manufacturer. The primary control board display assembly is only available as an individual component and does not include any other parts or the original appliance. This primary control board display assembly is designed for installation in LG refrigerators.

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
