• 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 control panel assembly replaces the front user interface and button/touch controls so you can restore normal control of oven functions and display information. Fits the original factory mounting and connections for a direct replacement. What it does:

• Replaces damaged or unresponsive front control buttons, touchpad, and status display
• Restores the ability to select cycles, start/stop, and change settings from the console
• Common symptom fix: unresponsive or intermittent control inputs and blank or incorrect display messages
• Works with the existing wiring harness and mounting points for a straightforward swap

• Disconnect power to the appliance before accessing internal components to avoid shock or injury
• Remove any trim or access panels to reach the control assembly
• Handle the display and ribbon cables carefully; flexing or pulling can damage connectors

Secures the washer’s tub and basket during moving to prevent internal damage. If the originals are missing after a move, install replacements for transport and remove them before using the washer.

What it does

• Locks the tub and basket to limit movement in transit
• Helps prevent suspension damage and internal rattles while relocating
• Replaces missing, bent, or stripped transport bolts
• Useful for moves, storage, or service shipments

What’s included
One shipping bolt assembly (sold individually).

Install notes

• Unplug power and turn off water before service
• Insert through the rear panel into the designated mounting point; tighten snugly—don’t overtighten
• Do not operate the washer with shipping bolts installed; remove all bolts after placement
• Some models use multiple bolts and lengths—match count/positions to your owner’s manual

Usage tip
After removal, bag and tape the bolts to the cabinet so they’re on hand for the next move.

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.

Includes sensor probe

This washer balance weight mounts to the outer tub to absorb vibration and stabilize the drum during spin. Replacing a damaged or missing weight helps restore smoother, quieter operation and reduces movement caused by unbalanced loads. What it does:

• Adds mass to the outer tub to counterbalance spinning loads
• Helps reduce vibration, banging, and "walking" during spin
• Supports proper spin speed and cycle completion
• Replaces a cracked, crumbling, or loose tub weight

• 1 balance weight

• Disconnect power and water supply before servicing
• Access the weight by removing the necessary panels
• Support the tub and hold the weight while removing/installing bolts; tighten evenly in a crisscross pattern
• Reuse existing mounting hardware and ensure all weights and mounting points are intact before testing

This Thermostat Assembly monitors and regulates internal temperature within the appliance's heating circuit. Replacing a failed thermostat restores proper heat control, helps prevent overheating, and can resolve common heating performance issues so cycles run correctly. What it does

• Senses internal temperature and opens/closes the heater circuit to maintain proper heat
• Provides over-temperature protection by cutting power at unsafe temperatures
• Helps ensure consistent heating performance throughout the cycle
• Helps with symptoms such as no heat, overheating/shutting off, or unusually long cycle times

• 1 thermostat assembly

• Disconnect power before servicing; allow hot components to cool
• Access the thermostat location (varies by model); note wire positions before removal
• Mount flush to the surface for accurate sensing; transfer original hardware if required
• After installation, test operation; use a multimeter for continuity checks if needed

This lamp assembly restores the interior drum light in your washer, improving visibility when loading and unloading. Replace a failed or damaged light to clearly see items and check the tub at a glance.

• Illuminates the washer drum when the door/light function is active
• Replaces a burned-out, flickering, or physically damaged lamp assembly
• Connects to the existing wiring harness and mounts in the factory location
• Symptoms include: drum light not turning on, intermittent flicker, or a cracked lens/housing

• Unplug the appliance before servicing; turn off water supply if opening the cabinet
• Access varies by model; may require removing the top/front panel and door boot clamp
• Disconnect the wiring connector carefully, seat the new assembly fully, secure it, and verify light operation before reassembly

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
