This pipe holder is a small plastic clip that secures tubing and small pipes inside the appliance, helping keep lines organized and preventing rubbing or disconnection. It restores proper routing and reduces vibration-related noises. What it does:

• Holds and secures water, drain, or refrigerant tubing to prevent sagging and chafing
• Keeps lines routed away from moving parts to reduce wear and noise
• Helps maintain proper tube alignment to avoid strain on fittings
• Commonly replaced when the original clip is cracked, broken, or missing

• Disconnect power and water before working on the appliance
• Inspect surrounding tubing and fittings for damage when replacing the clip
• Typically installs as a push-fit or snap-on clip; use gentle pressure and avoid forcing
• Replace broken or brittle clips to prevent tubing damage or leaks

This damper assembly controls airflow between compartments to help maintain consistent refrigerator temperatures and restore proper air distribution. It replaces a damaged or stuck damper that interferes with cooling balance. What it does:

• Regulates fresh food/freezer airflow by opening and closing the inlet
• Helps correct uneven temperatures or reduced cooling caused by a stuck or broken damper
• Stops unwanted drafts when the damper is closed
• Operates with the fridge's control system to respond to temperature changes

• Disconnect power to the appliance before starting any repair
• Access typically requires removing interior panels or shelving to reach the damper housing
• Handle plastic parts and wiring gently; avoid forcing connectors

This main control board is the appliance's primary electronic controller, coordinating user inputs, sensors and functions so the unit runs as intended. Replacing a faulty board restores proper electronic control and command response. What it does:

• Receives and processes signals from the user interface and sensors to run cycles and features
• Controls power distribution to motors, valves, displays and other electronic components
• Helps regulate timing, diagnostics and status reporting for the appliance
• Commonly linked to symptoms like no power to controls, unresponsive buttons, error codes, or unpredictable operation

• One main control board (electronic control PCB)

• Disconnect all power (unplug or trip the breaker) before accessing controls
• Handle the board by the edges and avoid static discharge; use an anti-static wrist strap if available
• Verify the part number on the original board matches before installing

This rail guide assembly supports and guides a sliding drawer/rack along its track so it opens and closes smoothly. Replacing a worn or broken guide restores proper alignment and motion, helping prevent sticking, jamming, or uneven travel.

• Supports and stabilizes the drawer/rack on its slide rail
• Helps ensure smooth, straight opening and closing
• Can address issues like binding, noise, or misalignment
• Replaces cracked, warped, or broken guide components

• Disconnect power and, if applicable, shut off water before servicing
• Remove the drawer/rack and retain any reusable hardware
• Install the new guide in the same orientation as the original
• Test movement for smooth travel before fully reassembling

This replacement compressor is made by LG. The compressor is the heart of the refrigerator and keeps pressure in the system while also adding the heat required to ensure the refrigerant works properly. This is the hardest-working component in the refrigerator and continually cycles on and off to do its job. That creates a great deal of wear and tear and will eventually cause the compressor to fail.Signs of a failing or failed compressor include hearing it cycle much more often than usual, the refrigerator not being as cold as usually, or the compressor not working at all. Replacing the compressor will require moving any perishables from the refrigerator to a safe, cold space. Unplug the refrigerator and pull it away from the wall. Locate the bottom access panel on the back of the appliance and remove it. The compressor will be located behind it.This compressor is a genuine OEM part and it is sold individually. It is compatible with LG refrigerators.

This guide assembly is a factory-style mounting guide used in TV chassis to position and support internal components, helping maintain correct alignment and stable operation during use and service. What it does:

• Provides a mounting and alignment point for internal TV components to keep assemblies stable
• Helps maintain proper spacing between parts to prevent rubbing, misalignment, or rattling noises
• Can restore correct fit where a damaged or worn guide causes loose panels or shifting components
• Useful when repairing or replacing adjacent parts that rely on the guide for proper positioning

• Guide assembly

• Disconnect power and remove the TV from its wall mount or stand before servicing
• Handle the panel and internal boards carefully to avoid damage; use non-marring tools
• Keep track of all screws and grounding hardware removed during disassembly for reassembly

This is a replacement mounting bolt used to secure appliance components and assemblies, restoring proper fit and reducing movement that can cause noise or misalignment. Use when a factory fastener is missing or damaged. What it does

• Fastens panels or internal components to maintain correct alignment and structural integrity.
• Prevents vibration-related noise and rubbing by holding parts securely in place.
• Restores secure connections after disassembly for service or repair.
• Helps eliminate intermittent movement that can lead to wear or leaks when a fastener is compromised.

• Use the correct bolt length and thread engagement for the application; do not force a mismatched fastener.
• Tighten to snug, manufacturer-specified torque when available; avoid overtightening to prevent stripping.
• Inspect surrounding parts (washers, nuts, threaded holes) and replace if worn or damaged.
• Disconnect power and follow all safety precautions before servicing the appliance.

The Door Switch is an OEM part for LG refrigerators. It is responsible for detecting whether the refrigerator door is open or closed, allowing the appliance to control the interior light and, in some models, the cooling functions accordingly.

Causes of a bad door switch can include wear and tear from frequent use, electrical issues, or physical damage to the switch mechanism. A faulty door switch can lead to improper operation of the refrigerator's light or cooling system, affecting overall performance.

Symptoms of a bad door switch include:

• Interior light not turning on or off properly
• Refrigerator not cooling properly or running continuously
• Door alarm not functioning correctly
• Intermittent or unresponsive switch operation

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

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.

This refrigerator sheath heater melts frost from the evaporator so air can circulate freely and the unit can cool properly. Replacing a failed heater helps restore even temperatures and reduce frost buildup in the freezer.

• Warms the evaporator coil during defrost cycles to clear ice
• Helps prevent restricted airflow, warm spots, and long run times
• Common failure symptoms include heavy frost on the evaporator, poor cooling, ice buildup on the back panel, or frequent defrost errors
• May cause sizzling sounds or water under the evaporator area during normal operation after replacement

• Unplug the refrigerator before service; defrost any heavy ice to access parts safely
• Access typically from the rear of the freezer compartment behind the evaporator cover
• Handle heater leads and evaporator fins carefully to avoid damage
• Secure all connectors before reassembly
