Parts for Lg LRSC21935SB: Machine Compartment Parts

The Drain Tube Assembly is an OEM part for LG refrigerators. This drain tube assembly is responsible for directing condensation and melt water that accumulates in the refrigerator away to the evaporator pan.

Causes can include cracks developing from limescale or mineral accumulation, flexing fatigue from repeatedly catching drips, or damage from improper cleaning methods.

Symptoms of a bad drain tube assembly include:

• Puddles or leaks developing underneath the refrigerator
• Poor air flow from vents and higher temperatures
• Ice or moisture buildup in refrigerator walls and seals
• Water stains or corrosion appearing inside the unit

This OEM LG part is also compatible with some Kenmore models.

THERMISTOR ASSEMBLY,PTC

The Compressor Overload Protector is an OEM replacement part for LG refrigerators. It plays an important safety role in protecting the compressor from damage due to excessive heat. Located near the compressor unit, the overload protector functions to shut off power to the compressor if temperatures become too high during operation.

Causes can include normal wear over time rendering it less responsive to temperature changes. Mineral or refrigerant deposits may also impede its ability to detect overheating conditions accurately.

Symptoms of a faulty overload protector include:

• Refrigerator fails to properly cool or the compressor does not run
• Circuit board or electrical component failure or burnout
• Lack of cold air production and higher than normal freezer/fridge temperatures

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

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 motor support damper sits between the refrigerator's compressor and base to absorb vibration and movement. Replacing a worn damper helps quiet rattles and humming from the back of the cabinet and keeps the compressor properly supported.

• Cushions the compressor to reduce transmitted vibration and noise
• Helps quiet humming, buzzing, or rattling from the lower rear of the refrigerator
• Maintains proper compressor alignment and support on the base pan
• Common signs of wear: increased vibration/noise, a cracked or flattened damper, or noticeable compressor movement when running

• Unplug the refrigerator and pull it forward to access the rear; allow the compressor to cool before working
• Support the compressor to remove load from the mount before loosening hardware
• Replace the damper and tighten mounting hardware evenly without over-compressing the rubber
• Avoid bending or stressing refrigerant tubing; wear gloves and eye protection

The Rear Evaporator Motor Grommet is an OEM part for LG refrigerators. It's designed to secure and cushion the evaporator motor, ensuring it remains in place and operates quietly. This grommet plays a crucial role in minimizing vibrations and noise from the motor, which can otherwise lead to a disruptive refrigerator operation.

Causes of a bad Rear Evaporator Motor Grommet can result from deterioration due to cooling and thawing cycles in the refrigerator. Physical damage during cleaning or servicing may cause a loose motor fit.  

Symptoms of a malfunctioning Rear Evaporator Motor Grommet include:

• Unusual noises or vibrations from the back of the refrigerator.
• The evaporator motor shifting out of place, which can affect cooling efficiency.
• Increased wear on the evaporator motor due to lack of proper cushioning and support.

This OEM LG part is also compatible with some Kenmore models.

This holder is a small mounting bracket used to secure internal components in place, helping keep parts aligned and stable for reliable operation. It provides a direct, OEM-compatible replacement to restore proper fit and function. What it does

• Secures and supports nearby components to prevent shifting or vibration.
• Restores proper alignment where a worn or broken holder causes rattling or loose parts.
• Helps maintain normal operation by keeping assemblies seated correctly.
• Works behind panels or inside assemblies where a dedicated bracket is required.

• One holder/mounting bracket as shown.

• Installation generally requires removing the panel or access cover where the holder is located.
• Use proper fasteners shown in your appliance; replace any damaged screws or clips as needed.
• Disconnect power before servicing electrical appliances to reduce shock risk.

The Drier Assembly is an OEM part for LG refrigerators. This part removes moisture and contaminants from the refrigerant, ensuring the system operates efficiently and effectively. The drier assembly helps maintain the proper function of the compressor and other cooling components, contributing to the longevity and performance of the refrigerator.

Causes of a bad drier assembly can include clogs from debris, wear and tear over time, or contamination from moisture or refrigerant leaks.  

Symptoms of a bad drier assembly include:

• The refrigerator not cooling properly
• Frost or ice buildup on the evaporator coils
• Increased noise from the compressor
• Reduced efficiency and higher energy consumption
• You should replace the drier assembly if it becomes faulty or damaged.

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

This evaporator fan motor assembly moves cold air across the evaporator and throughout the fresh food compartment to keep temperatures even and cooling consistent. Replace it to restore proper airflow and help eliminate warm spots or frost buildup. What it does

• Circulates chilled air from the evaporator into the refrigerator section
• Helps maintain stable temperatures and consistent cooling performance
• Replaces a motor that is noisy, stalls intermittently, or doesn't run
• Helps with symptoms like weak/no airflow from refrigerator vents, a warm fridge compartment, or ice/frost on the rear interior panel

• One refrigerator fan motor assembly

• Disconnect power to the refrigerator before servicing
• Access the assembly behind the rear interior panel of the refrigerator section
• Remove the panel, disconnect the wire harness, and release the motor assembly from its mounts; transfer any model-specific fan blade or isolators if required
• Ensure the fan spins freely and wiring is clear of the blade before restoring power; use care around sharp edges and the evaporator coil

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
