Parts for Lg LSC27921TT: Dispenser Parts

The LG Refrigerator Water Filter is an OEM Replacement Part. It is designed to improve the quality of water and protect refrigerators and ice machines from sediment deposits. This NSF-Certified filter effectively reduces iron and particulates. It also preserves beneficial minerals like fluoride. The filter measures 5.6 inches high and 3.3 inches in diameter.

It is installed by removing the top shelf and pulling the old filter downward. Then turn it counter-clockwise, and replace it with the new filter aligned in a horizontal position. To ensure the best performance and the removal of trapped air and contaminants, it's recommended to flush the dispenser with 2.5 gallons of water in alternating cycles. If your model includes a water filter indicator, press and hold the Filter or Reset button for 5 seconds after installation. With a lifespan of 6 months and a 500-gallon capacity, this filter provides both quality and longevity.

This dispenser lever holder is the mounting bracket behind the refrigerator's dispenser paddle. It supports and aligns the lever and switch so water or ice dispenses reliably when the paddle is pressed.

• Holds and guides the dispenser lever and actuator switch inside the dispenser housing
• Provides a secure pivot point for smooth paddle movement
• Helps ensure consistent activation of water and ice dispensing
• Damage can cause a loose or stuck paddle, intermittent dispensing, or no dispense

• Disconnect power and shut off the water supply before servicing
• Remove the dispenser panel/escutcheon to access the lever assembly; note part orientation
• Transfer the lever, switch, and return spring to the new holder and secure with the original fasteners
• Restore power/water and test dispensing before reinstalling trim

This small torsion spring restores tension to the dispenser ice door lever so the chute door snaps closed after dispensing. It helps keep warm air and moisture out, reducing frost, condensation, and stray ice from the dispenser.

• Provides return tension for the dispenser ice chute door/lever
• Helps the chute door seal properly to limit warm air infiltration
• Worn or broken springs may cause the ice door to stay open or close slowly
• Symptoms can include frost/ice buildup in the chute, moisture at the dispenser, or cubes dropping/clumping

• Unplug the refrigerator or switch off the circuit breaker before servicing
• Remove the dispenser trim/panel to access the ice door mechanism; note spring orientation with a photo
• Use needle-nose pliers and eye protection—small springs are under tension and can snap
• After installation, cycle the dispenser to confirm the door opens/closes freely and seals

The Actuator Lever is an OEM part for LG refrigerators. It plays a crucial role in the dispensing mechanism of the refrigerator, allowing for the controlled release of water and ice. The lever is designed to interact seamlessly with the internal components of the dispenser to ensure smooth and reliable operation.

Over time, the actuator lever can wear out or become damaged due to frequent use or mishandling. Causes of a bad actuator lever include physical wear, breakage from excessive force, or deformation due to constant usage.

Symptoms of a bad actuator lever include:

• Difficulty in dispensing water or ice
• The lever sticking or not returning to its original position
• Unresponsive dispenser mechanism
• Unusual noises when using the dispenser

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

This replacement nut is a simple fastener used to secure internal components and panels. It restores proper attachment where a loose or missing nut causes vibration, noise, or parts to shift. What it does:

• Secures components, brackets, or panels in place to maintain appliance stability
• Prevents parts from loosening during operation, reducing rattles and vibration
• A missing or damaged nut can allow movement that leads to noise or improper alignment
• Use as a direct hardware replacement when the original nut is lost or worn

• Disconnect power (and water, if applicable) before accessing internal parts
• Start threads by hand to avoid cross-threading; tighten with the appropriate wrench or socket
• Replace if threads are stripped or the nut is damaged
• Refer to the parts diagram for the correct mounting location

The Dispenser Micro Switch is an OEM part for LG refrigerators. It is a component of the ice and water dispensing system, responsible for activating the dispenser when the lever is pressed. 

Causes of a bad Dispenser Micro Switch can include mechanical wear from frequent use, failure due to moisture or debris affecting the switch’s contacts, or electrical faults that prevent proper signaling.

Symptoms of a bad Dispenser Micro Switch include:

• The dispenser not releasing ice or water when the lever is pressed.
• Continuous dispensing or dripping after the lever is released.
• Intermittent or no response from the dispenser controls.

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

The Ice Door Solenoid Assembly is an OEM replacement part for LG refrigerators. This assembly controls the opening and closing of the ice door, which allows ice to be dispensed from the freezer to the exterior of the appliance. When you request ice, the solenoid activates, opening the ice door and permitting ice to pass through.

Symptoms of a bad Ice Door Solenoid Assembly include:

• Ice door not opening or closing properly
• Failure to dispense ice
• Ice accumulating or jamming at the dispenser

Causes for a malfunctioning Ice Door Solenoid Assembly can include electrical issues such as faulty wiring, wear and tear from frequent use, or mechanical problems affecting the solenoid's ability to move the ice door.

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

This replacement duct cap assembly covers and seals a designated duct opening inside the appliance. It helps direct flow through the intended path and keeps out debris so the system can operate as designed.

• Covers and seals a duct opening to maintain correct internal flow paths
• Helps prevent air/moisture leaks and blocks dust or debris entry
• Replaces a cracked, warped, loose, or missing cap assembly
• Symptoms can include visible damage, a cap that won't stay seated, leak noises, or rattling from the duct area

• Disconnect power; turn off water supply if applicable before servicing
• Access the duct location, remove the damaged cap, and retain any screws/clips
• Clean mating surfaces; transfer any reusable seals or hardware to the new assembly
• Seat and secure the new cap without overtightening; restore power and check for a snug, leak-free fit
