The Air Chamber is an OEM part for LG washing machines. This part connects to the pressure switch and ensures the washer machine fills with the correct amount of water for the selected cycle. 

Causes of a bad  Air Chamber can include clogging due to detergent residue or debris, cracks or perforations that lead to air leaks, and aging of the material, which might compromise its integrity and function.

Symptoms of a faulty Air Chamber include:

• Inaccurate water level readings leading to overfilling or insufficient water during cycles
• Unusual noises during the fill cycle, indicating air escaping
• The washing machine failing to start the wash cycle due to improper water level detection
• Error codes displayed on the machine that relate to water level issues

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

The Motor Wiring Harness is an OEM replacement part for LG washing machines. It is responsible for supplying power from the washer control board to the motor and related components. The wiring harness conducts electrical current, allowing for the operation of the pump, motor, and other vital systems. 

Causes of a bad motor wiring harness can include damage due to repetitive use and wear over long periods of time, exposure to moisture, impact or abrasion damage, or faulty insulation leading to electrical shorts.

Symptoms of a bad motor wiring harness include: 

• The washer failing to start or functioning intermittently
• Strange noises coming from the motor or other electrical components
• Slow or ineffective spinning or agitation  
• Error codes displayed on the control panel

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

Includes sensor probe

The door boot gasket seals the opening between your front-load washer's door and outer tub, keeping wash water contained. Replace it if the boot is torn, deformed, or heavily mildewed to restore a reliable, watertight seal.

• Forms a watertight seal between the outer tub and door opening
• Prevents leaks from the front of the washer during wash and spin
• Flexible design maintains the seal as the drum moves
• Common failure signs: water on the floor at the front, dripping at the door, visible rips/cracks, or the boot pulling loose

• Unplug the washer and turn off water supply; wear gloves to avoid sharp edges
• Access the boot by removing panels as required for your model; note hose positions and alignment
• Release the outer and inner retaining clamps/springs and remove the old gasket
• Seat the new gasket evenly, align indexing features/ports, reinstall clamps securely, and run a quick test for leaks

This pivot hanger assembly supports and stabilizes the appliance component it mounts to, restoring smooth movement and alignment. Replace a worn or damaged pivot to reduce noise and prevent misalignment that can affect operation. What it does:

• Acts as the pivot point for the hanger to support the drum/door assembly and maintain correct alignment
• Helps eliminate squeaks, scraping, or jerky motion caused by a worn pivot
• Prevents sagging or uneven movement that can lead to rubbing or binding
• Restores proper mechanical support so the appliance operates quietly and reliably

• Unplug the appliance or disconnect power before beginning any repair
• Basic hand tools may be required; follow the appliance service manual for disassembly steps
• Inspect surrounding components (mounts, bearings, fasteners) and replace if worn

This lifter assembly is the drum baffle inside the washer's inner tub. It lifts and tumbles laundry as the basket turns—replacing a cracked or missing lifter restores proper turnover, helps prevent fabric damage, and quiets thumping noises.

• Provides the lift/turn action that moves clothes through water and detergent
• Helps distribute loads to reduce tangling and improve cleaning results
• A loose, broken, or missing baffle can cause rattling or scraping noises
• Damage can lead to poor turnover or fabric snagging

• Disconnect power before servicing; wear gloves—the inner drum edges can be sharp
• Access from the drum opening; remove the old lifter by releasing tabs or removing screws (varies by model)
• Align the new lifter with the inner-tub slots, lock tabs in place, and secure as designed
• Verify all baffles are firmly attached before running a test cycle

This balance weight stabilizes the washer tub during spin cycles to reduce vibration and excessive movement, helping restore quieter operation and prevent further stress on suspension components and fasteners. What it does

• Counters the rotating tub to reduce vibration and rocking during spin cycles.
• Helps stop excessive movement, banging noises, and uneven spinning that can indicate an unbalanced load or worn mounting hardware.
• Replaces a damaged or missing counterweight to regain stable, consistent spin performance.
• Mounts to the washer cabinet/tub area and secures with factory fasteners.

• Disconnect power and water supply and run a drain/spin or remove standing water before beginning work.
• Removing the washer cabinet or front panel is often required; support the tub and components while you work.
• Use appropriate hand tools and keep OEM fasteners for reinstallation; follow the appliance service manual for exact steps.
• Wear gloves and eye protection.

Locking pin for shock absorber.

This is a replacement single electrical harness that restores the factory wiring connection between components. It provides a like-for-like connection to help return affected functions to normal operation when wiring is damaged. What it does:

• Carries electrical signals/power between components and the appliance control circuits
• Replaces frayed, melted, or broken wiring that can cause intermittent or complete function failure
• Commonly used when a component has no power, a circuit is open, or functions stop responding
• Helps eliminate loose connector issues that cause intermittent operation or error codes

• One (1) single electrical harness (part 6877ER3003C)

• Always disconnect power (unplug or shut off breaker) before inspecting or replacing wiring
• Match connector shapes and pin counts; do not force connectors—verify secure seating
• Route and secure the harness per factory paths and clips to prevent chafing or heat exposure
• If you see melted connectors, burned insulation, or repeated failures,

This rear cover is the outer housing panel that protects the appliance's internal components and helps maintain proper airflow and support. It replaces a cracked, broken, or missing rear housing panel to restore protection and fit. What it does:

• Shields motors, wiring, vents, and other internal parts from dust, debris, and accidental contact
• Helps direct airflow and maintain correct ventilation for safe operation
• Restores proper mounting points and prevents rattles from a loose or damaged back panel
• Commonly replaced when there is visible damage, missing mounting tabs, or unusual noise from the rear

• One rear cover

• Disconnect power (unplug or switch off circuit breaker) before starting any repair
• Removal usually requires taking off the exterior panels and a few screws or clips; retain all fasteners for reinstallation
• Watch for sharp edges and wear protective gloves; handle internal wiring and components gently

This pump hose routes washer tub water to the drain pump, helping remove wash water during the drain cycle. Replace a cracked or clogged hose to stop leaks and restore normal draining. What it does:

• Channels tub water to the drain pump so the washer can expel water during drain/spin cycles.
• A worn or cracked hose can cause water leaks under the machine.
• Blocked or collapsed hoses can contribute to slow or incomplete draining.
• Compatible replacement for the OEM pump hose connection on qualifying LG washers.

• One pump hose (single hose as shown)

• Disconnect power and turn off water supply before beginning any repairs.
• Confirm correct routing and secure clamps when installing to prevent leaks.
• Inspect adjacent clamps and fittings for wear; replace if corroded or damaged.

This holder is a small mounting bracket that secures internal components and keeps assemblies aligned for reliable operation. It replaces a worn or broken bracket to stop rattling and prevent parts from shifting. What it does

• Secures and positions nearby components or assemblies to maintain correct alignment
• Prevents vibration, rattling, or intermittent contact caused by a loose or cracked bracket
• Restores proper spacing so sensors, panels, or moving parts operate smoothly
• Helps prevent further wear or damage from misaligned parts

• One holder as shown

• Turn off power and disconnect the appliance before attempting any repairs
• Installation typically requires basic hand tools; save removed screws and clips for reassembly
