Lrfd21855st Parts

The Door Switch is an OEM part for LG refrigerators. It is responsible for detecting whether the refrigerator door is open or closed, allowing the appliance to control the interior light and, in some models, the cooling functions accordingly.

Causes of a bad door switch can include wear and tear from frequent use, electrical issues, or physical damage to the switch mechanism. A faulty door switch can lead to improper operation of the refrigerator's light or cooling system, affecting overall performance.

Symptoms of a bad door switch include:

• Interior light not turning on or off properly
• Refrigerator not cooling properly or running continuously
• Door alarm not functioning correctly
• Intermittent or unresponsive switch operation

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

Refrigerator running hot or not cooling? A failed condenser fan motor prevents heat removal from the compressor. DIY repair in under an hour.

Structural bracket that secures the refrigerator cover panel to the frame. Replace if cracked, bent, or broken to restore proper alignment and fit.

Fix frost buildup and uneven cooling in your refrigerator with this evaporator defrost heater. Melts ice from coils during defrost cycles. Moderate repair.

Refrigerator won't power on or loses power intermittently? This power cord assembly replaces frayed or damaged cords to restore safe, reliable operation.

Secures and guides your refrigerator door for smooth opening and closing. Replace if door sags, rubs, or won't seal properly. Confirm fit by model number.

Replacement refrigerator door hinge that restores smooth pivoting and proper door alignment, helping the door open and close reliably and maintain an airtight seal to preserve cooling performance. What it does:

• Supports the refrigerator door and allows it to pivot smoothly.
• Replaces worn, bent, or damaged hinges that cause door sag or misalignment.
• Helps reduce noisy or grinding door operation when the hinge is failing.
• Promotes an even door seal to help maintain internal temperature consistency.

• Unplug the appliance and remove food from nearby shelves before starting work.
• Support the door while removing hinge fasteners to prevent dropping or damage.
• Reinstall using the original hardware; align the door and tighten fasteners securely but avoid overtightening.

This is the sensing arm lever for the ice maker inside your freezer compartment. It monitors the level of ice in the bin and signals the ice maker to stop producing ice when the bin is full. Replace this part if your ice maker runs continuously and overfills, or if it fails to produce ice because the arm is broken or stuck.

Fix a too-cold fridge or freezing food with this air damper assembly. Controls airflow between compartments to restore proper temperature balance.

Center door hinge assembly for bottom-mount refrigerators. Supports the door weight and maintains proper alignment. Replace if cracked, worn, or broken.

Replacement shelf panel that covers and protects the Magic Room compartment in your refrigerator. Replaces cracked, chipped, or missing panels.

This temperature sensor (thermistor) detects internal appliance temperature and sends readings to the control board so the unit maintains proper cooling. Replacing a failing sensor restores accurate temperature monitoring and helps prevent spoilage. What it does:

• Measures internal temperature and provides a resistance-based signal to the control board
• Helps the control system regulate compressor and defrost cycles
• Commonly causes warm or fluctuating temperatures, prolonged cooling, or temperature-related error codes when failing
• Works as a direct-sensing temperature input — not a user control or switch

• One temperature sensor/thermistor (single part as shown)

• Unplug the appliance or switch off power at the breaker before servicing
• Handle the sensor and its thin leads carefully to avoid damage during removal and installation
• Route and secure wiring so it does not contact moving parts or sharp edges

Secures internal components to prevent rattling and shifting. Replace if bracket is damaged, broken, or parts have become loose. Verify fit with model number.

Plastic trim cap that snaps over exposed fasteners and mounting posts on your refrigerator. Replace if cracked, broken, missing, or discolored.

Protective grille cover that shields the cooling fan and directs airflow in your refrigerator. Replace if cracked, broken, or missing to restore finish.
