Lsc21943st Parts

This motor start/run capacitor helps the appliance motor or compressor start and run more reliably, restoring proper motor performance and reducing symptoms caused by a weak or failed capacitor. What it does:

• Provides the momentary electrical boost motors or compressors need to start
• Helps maintain stable motor operation during run cycles
• Resolves symptoms like motors that hum but won't start, intermittent starting issues, or cycling problems
• Replaces a worn or failed capacitor to restore consistent performance

• One replacement capacitor as shown

• Disconnect power before servicing and verify the appliance is de-energized
• Capacitors can hold charge — discharge safely before touching terminals
• Match terminal type and mounting location to the original part; do not force connections

The Drain Tube Assembly is an OEM part for LG refrigerators. This drain tube assembly is responsible for directing condensation and melt water that accumulates in the refrigerator away to the evaporator pan.

Causes can include cracks developing from limescale or mineral accumulation, flexing fatigue from repeatedly catching drips, or damage from improper cleaning methods.

Symptoms of a bad drain tube assembly include:

• Puddles or leaks developing underneath the refrigerator
• Poor air flow from vents and higher temperatures
• Ice or moisture buildup in refrigerator walls and seals
• Water stains or corrosion appearing inside the unit

This OEM LG part is also compatible with some Kenmore models.

The Door Stopper Assembly is an OEM component specifically designed for LG refrigerators. It secures the fridge door in fully closed and aligned positions. 

The stopper assembly utilizes a pneumatic cylinder and integrated mounts to softly cushion door movement. This allows for smooth closing with an audible click to confirm proper sealing.

Causes of a bad stopper assembly can include cracked or leaking air cylinders after years of use. Loose or sheared mounting hardware may also cause improper alignment and restricted closure.

Symptoms of a bad door stopper assembly include: 

• Gaps forming around the door seal when closed
• Doors difficult to latch fully or align correctly  
• Premature cooling loss from unsealed openings

Replacing this LG part restores a snug, confirmed door shut. The OEM stopper components ensure dependable closing effort for efficient operation. This replacement is compatible with some Kenmore models as well.

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.

Note: 90 degree elbow coupler (Fits 1/4" diameter tubing on each end) For 5/16" elbow connector, order part# 4932JA3009B.

The Water Line Union is an OEM part for LG refrigerators. This component connects sections of the water line, ensuring a secure and leak-free passage of water to the refrigerator's icemaker and water dispenser. It is an elbow tube union connector, which connects two tubes at a 90-degree angle.

Causes of a bad water line union can include wear and tear from frequent use, damage from high water pressure, or deterioration due to mineral buildup and age. A compromised union can lead to water leaks and disruption in the water supply.

Symptoms of a bad Water Line Union include:

• Water leaks around the connection points
• Reduced water flow to the icemaker or water dispenser
• Puddles or moisture near the refrigerator
• Unusual noises from the water line

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

A film radial capacitor used in appliance electrical assemblies to stabilize voltage and support motor and control circuits. Replaces a worn or failed film capacitor to restore consistent operation and reduce electrical noise. What it does:

• Smooths and stabilizes voltage in motor and control circuits to help maintain reliable operation
• Reduces electrical noise that can cause humming or erratic behavior in appliances
• Helps ensure consistent motor start/run performance when the capacitor is the cause of symptoms
• Commonly replaced when appliances exhibit intermittent starts, humming, or control board errors linked to compromised capacitors

• Disconnect power to the appliance before accessing electrical components
• Discharge the capacitor safely before touching terminals to avoid shock
• Observe correct polarity/terminal orientation and secure connections per OEM guidance

It contains the defrost temperature sensor and the defrost thermal fuse.

This motor bracket assembly secures the appliance motor to the cabinet, keeping the motor properly positioned for reliable operation and reducing vibration or rubbing. Replaces a worn or damaged motor mounting bracket to restore stability. What it does:

• Holds the motor in place to maintain proper belt alignment and drivetrain geometry
• Prevents motor movement that can cause loud noise, grinding, or rubbing
• Reduces excessive vibration that can transfer to the cabinet or other components
• Helps maintain safe, consistent motor operation during spin or drive cycles

• Disconnect power (and gas if applicable) before starting any repair
• Support the motor before removing mounting hardware to avoid strain on wires or components
• Tighten all fasteners to OEM torque specs; replace any damaged brackets or fasteners
• Test operation after installation and re-check for proper alignment and noise

Note: 90 degree elbow coupler (Fits 5/16" diameter tubing on each end) For 1/4" elbow connector, order part# 4932JA3009A.

A replacement guide rail that supports and guides a sliding component for smooth, stable movement and proper alignment. Use this rail to restore reliable sliding action and reduce binding or uneven travel. What it does

• Supports and guides a drawer, rack or movable assembly so it slides smoothly along its track
• Helps keep the component aligned to prevent binding, catching or uneven travel
• Reduces wear on mating parts by providing a stable sliding surface
• Can help stop scraping, grinding or noisy movement caused by a damaged rail

• One guide rail

• Disconnect power and remove any stored items before beginning service
• Basic hand tools typically required; follow the OEM service manual for panel removal and routing
• Align the rail carefully during installation to ensure smooth operation and prevent binding
• If you encounter broken clips or fasteners, replace them with OEM replacements for a secure fit
