Parts for Lg LSC27991TT: 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.

The Condenser Fan Blade is an OEM replacement part for LG refrigerators. The condenser fan motor blade is located on the condenser fan motor which is usually located on or near the compressor at the back of the refrigerator. This part is responsible for circulating air over the condenser coils. This helps to remove heat from the condenser and evaporate water in the defrost drain pan.

Causes of blade failure can include normal wear over extended runtime, accumulated dirt and dust impeding airflow, or physical impact damage.

Symptoms of a faulty condenser fan blade include:

• Refrigerator fails to properly cool and maintain temperatures
• Condenser unit runs excessively as heat fails to dispel
• Abnormal noises such as grinding or squealing emanate from the condenser area

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

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 cover tube is a molded protective housing that shields internal components and wiring from wear, heat, and debris. It helps maintain safe operation and prevents rubbing or chafing that can lead to damage. What it does:

• Covers and protects internal wiring, hoses or assemblies from contact and abrasion
• Helps direct airflow and keeps debris away from sensitive parts
• Reduces noise caused by rubbing or loose components
• Preserves component alignment and prevents premature wear

• Disconnect power to the appliance before beginning any repair.
• Installation requires partial disassembly of the appliance; keep track of screws and clips.
• Use OEM replacement and follow the service manual for correct orientation and torque of fasteners.
• If you see damaged wiring or other compromised parts, replace or repair those items before reinstalling the cover tube.

This holder is a small mounting bracket that secures a mating component in place inside the appliance. Replacing a cracked or missing holder restores a firm, rattle-free fit and proper alignment.

• Provides a stable mount for the designated part
• Prevents shifting and vibration that can cause noise or premature wear
• Common signs of failure: broken tabs, stress cracks, or the attached part sagging or falling out
• When damaged, the connected component may be loose, noisy, or misaligned

• Disconnect power; if working near water tubing, also shut off the water supply
• Note the original orientation and mounting points; take a photo before removal
• Reuse existing fasteners and avoid overtightening to prevent cracking the plastic
• Ensure the attached component is secure and clears any moving parts before restoring power
