The Drain Pipe Assembly is an OEM replacement part for LG refrigerators. It is a plastic tubing system that collects and removes liquid condensation from evaporator coils. Proper drainage is crucial to minimizing frost buildup and ensuring optimal cooling of food storage areas. 

Symptoms of a bad drain pipe assembly include:

• Excessive frost or ice accumulation inside the refrigerator
• Puddling or leaks detected near evaporator housing
• Slow draining allowing water to pool versus emptying fully
• Cracks or breaks in the tubing prevent complete fluid removal

Causes are typically mineral sediment clogging drainage paths or deteriorating plastic from constant use. This OEM LG replacement pipe restores reliable condensate removal to maintain peak efficiency.

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

This overload protector is a safety device that helps prevent compressor damage by stopping electrical current during overheating or locked-rotor conditions. It's a direct-fit replacement that restores proper compressor protection and helps keep the appliance running safely. What it does:

• Protects the compressor by interrupting power if the motor overheats or experiences an electrical fault
• Common symptom: refrigerator runs but compressor won't start or only hums
• Common symptom: fridge cycles frequently or doesn't maintain temperature due to compressor protection tripping
• Works with the start device to help ensure reliable compressor startup

• Disconnect power before servicing; work only with the appliance unplugged
• Access typically requires removing the rear access panel to reach the compressor area
• Replace using the same mounting and terminal connections; ensure secure electrical connections

This PTC cover protects the refrigerator's PTC/compressor start device from dirt, moisture and accidental contact, helping the start device operate reliably. It's a simple replacement that restores the protective enclosure for the start assembly. What it does:

• Shields the PTC/compressor start relay and wiring from debris and moisture that can cause malfunctions
• Helps prevent accidental shorting or contact with terminals during operation or service
• Can resolve symptoms where the start device is exposed or the compressor area shows visible wear or damage
• Maintains correct positioning and protection of the start components for consistent compressor starting

• One PTC cover (protective enclosure) as shown

• Disconnect power to the appliance before starting any repair
• Replace only when the start device or cover is exposed and you can access compressor/start assembly safely
• Avoid bending or stressing terminals and wiring when removing or installing the cover

This is a replacement retaining pin used to secure small moving parts and assemblies in compatible LG appliances. It restores proper alignment and holds components in place so assemblies operate smoothly. What it does:

• Secures and locates components within an assembly to prevent shifting or disengagement
• Helps maintain proper alignment for moving parts that can cause noise or malfunction when loose
• Commonly used where a small, durable metal pin is needed to retain clips, levers, or linkages
• Simple, single-purpose part — replacement when the original is bent, worn, or missing

• One retaining pin

• Unplug the appliance or disconnect power before servicing
• Access the affected assembly per the appliance service instructions; small fasteners or clips may need removal
• Use pliers or appropriate hand tools to remove/install the pin; avoid forcing to prevent damage
• Keep track of orientation and any associated clips or washers during disassembly

This restrainer is a small retaining clip that helps secure moving or removable components in place, reducing rattles and keeping parts aligned for reliable operation. It's a simple replacement for worn or broken clips. What it does:

• Holds a cover, panel, or door-related component in proper position to prevent shifting
• Reduces noise caused by loose or vibrating parts
• Restores original fit where a broken or missing clip allows movement
• Simple mechanical function — no electrical connections or calibration

• One restrainer

• Disconnect power (and water if applicable) before beginning repairs
• Inspect surrounding mounting points for damage; replace any broken tabs or fasteners
• Typically installs with basic hand tools; align clip and press or snap into place until secure

This damper controls airflow between compartments to help maintain proper temperatures and consistent cooling. It replaces a worn or broken damper to restore normal airflow and temperature balance inside the appliance. What it does:

• Regulates air flow between compartments so the refrigerator can maintain set temperatures
• Helps reduce uneven cooling and temperature swings caused by a stuck or broken damper
• Works as part of the appliance's air distribution system to route cooled air where needed
• Common symptom: compartment temperature too warm or inconsistent airflow noise from the damper area

• One damper assembly

• High-level replacement; access usually requires removing interior panels or duct covers
• Disconnect power before any repair to avoid shock or injury
• Handle with care to avoid bending or damaging mounting tabs and linkage

This condenser fan assembly circulates air across the condenser coils and compressor to remove heat from the refrigeration system. Replacing a failing fan helps restore efficient cooling performance and protects the compressor from overheating. What it does:

• Draws air through the condenser coils to dissipate heat
• Supports proper system pressures and overall cooling efficiency
• Helps maintain stable temperatures in both compartments
• Common symptoms include the fan not running, loud noise from the rear, warm cabinet temperatures, or a very hot compressor area

• Pre-assembled fan motor with blade and mounting bracket

• Disconnect power before servicing; use gloves to protect against sharp edges
• Access the lower rear compartment and remove the back cover to reach the fan
• Note wire positions; move over any reusable grommets or screws and secure the assembly firmly
• The blade spins freely and is oriented to move air across the condenser; clean coils before restoring power

The Defrost Sensor Assembly is an OEM part for LG refrigerators. It plays a critical role in the defrost system by monitoring the temperature of the evaporator coil to ensure that it remains at the optimal temperature to prevent frost buildup. The sensor sends signals to the control board, triggering the defrost cycle when necessary.

Over time, the defrost sensor assembly can fail due to wear and tear, electrical issues, or exposure to moisture and temperature fluctuations. When the defrost sensor malfunctions, it can cause improper defrost cycles, leading to excessive frost buildup, reduced cooling efficiency, or the refrigerator not defrosting at all.

Symptoms of a bad defrost sensor assembly include:

• Excessive frost buildup on the evaporator coils
• Refrigerator or freezer not maintaining the correct temperature
• Increased energy consumption
• Refrigerator not defrosting properly

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

The Damper Motor Support is an OEM part for LG refrigerators. It holds the damper motor in place, ensuring proper air flow between the refrigerator and freezer compartments. This support is essential for maintaining the correct temperature balance within the appliance.

Causes of a bad damper motor support can include wear and tear over time, physical damage from impacts, or exposure to moisture that can weaken the support structure. A faulty support can lead to improper functioning of the damper motor, affecting the refrigerator's cooling efficiency.

Symptoms of a bad Damper Motor Support include:

• Inconsistent temperatures between refrigerator and freezer
• Unusual noises coming from the damper area
• Visible damage or cracks in the support
• Reduced cooling efficiency

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

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
