The Shipping Bolt is an OEM part for LG washing machines, designed to secure the washing machine's drum during transportation. These bolts are important for preventing damage to the drum and suspension system by immobilizing the drum, thereby avoiding any excessive movement or vibrations that could occur while moving the appliance. 

Causes of a bad shipping bolt can include improper removal during installation, damage from handling, or degradation over time if it was left in place during operation. A damaged or missing shipping bolt can lead to issues with the washing machine's drum alignment and overall stability.

Symptoms that indicate the shipping bolts need removal or installation include:

• Excessive noise or vibrations during operation, suggesting the bolts were not removed after installation.
• Damage to the washing machine's drum or suspension system after moving the appliance without the bolts properly installed.

This OEM LG part can also be used on Kenmore/Sears appliances. 

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 Stator Assembly is an OEM replacement part for LG washing machines. It is an electrical component inside the motor that converts rotational motion to electrical energy to power spinning motions.  Note: For the RPS or Hall Sensor, order part number AP7015078.

Symptoms of a faulty stator include:

• Slow or inefficient spinning, rubbing noises  
• The machine failing to fully drain or spin clothes
• Repeated blowouts or failure of related motor components

Causes can be wear and tear over extended use. Environmental factors like dust and moisture exposure may degrade insulation integrity. 

This OEM stator is also compatible with some Kenmore front-load washer models.

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
