THERMISTOR ASSEMBLY,PTC

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

The Drier Assembly is an OEM part for LG refrigerators. This part is responsible for removing moisture and contaminants from the refrigerant. This ensures that the refrigerant circulates effectively and efficiently, preventing damage to other components and maintaining the refrigerator's cooling performance.

Causes of a bad Drier Assembly can include contamination from moisture entering the refrigerant lines, blockages from debris or particulates, and general wear and tear over time that reduces its effectiveness.

Symptoms of a bad Drier Assembly include:

• Reduced cooling efficiency or warm refrigerator temperatures
• Unusual noises from the refrigeration system
• The compressor running continuously or cycling frequently
• Frost buildup on the evaporator coils due to improper refrigerant flow

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

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

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.

A direct-replacement AC motor assembly for compatible LG appliances that restores rotation and airflow so your appliance can tumble, circulate air, or run pumps as designed. Simple swap when the original motor fails. What it does

• Powers the appliance's rotating components to enable drum or fan movement.
• Restores normal airflow and agitation when a worn motor causes weak or no rotation.
• Helps eliminate grinding, squealing, or burning-smell symptoms tied to a failing motor.
• Stops intermittent start/stop or complete non-start conditions caused by motor failure.

• One (1) AC motor assembly as shown.

• Disconnect power before servicing to avoid shock—unplug the appliance or turn off the breaker.
• Partial disassembly of the cabinet or access panels is usually required; follow the service manual for your model.
• Inspect mounting hardware and wiring; replace any damaged fasteners or connectors.

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

Replacement cooling motor (mechanical) that circulates air through the refrigerator's cooling channels to help maintain even temperatures and prevent overheating. Installs in the fan assembly to restore proper airflow and cooling performance. What it does:

• Drives the appliance fan to move air across the cooling system so compartments stay at the correct temperature.
• Restores airflow when a failed motor causes poor cooling or uneven temperatures.
• Failing motor symptoms can include the refrigerator running warm, frost buildup, or the fan not spinning.
• Can produce loud humming, clicking, or grinding noises when worn or damaged.

• Disconnect power to the appliance before starting work to avoid shock.
• Access may require removing interior or rear panels; retain all mounting hardware.
• Handle electrical connectors gently and secure wiring per original routing; tighten mounting screws snugly but do not overtighten.
