Parts for Lg LSC21943ST / ASTCLGA: Section 5 Parts

The LG Refrigerator Water Filter is an OEM Replacement Part. It is designed to improve the quality of water and protect refrigerators and ice machines from sediment deposits. This NSF-Certified filter effectively reduces iron and particulates. It also preserves beneficial minerals like fluoride. The filter measures 5.6 inches high and 3.3 inches in diameter.

It is installed by removing the top shelf and pulling the old filter downward. Then turn it counter-clockwise, and replace it with the new filter aligned in a horizontal position. To ensure the best performance and the removal of trapped air and contaminants, it's recommended to flush the dispenser with 2.5 gallons of water in alternating cycles. If your model includes a water filter indicator, press and hold the Filter or Reset button for 5 seconds after installation. With a lifespan of 6 months and a 500-gallon capacity, this filter provides both quality and longevity.

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.

Protective cover for your refrigerator's PTC and compressor start device assembly. Replace if cracked, melted, or missing to shield components from damage.

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.

Refrigerator not cooling or making unusual noises? This compressor pipe joint connects sealed system components. Professional installation recommended.

Fix refrigerator not cooling properly or running constantly with a new drier assembly. Removes moisture from refrigerant. Requires EPA-certified technician.

Fix refrigerator not cooling properly or running constantly with a new drier assembly. Removes moisture from refrigerant. Requires EPA-certified technician.

Fix error code CF, warm spots, or inconsistent cooling with this evaporator fan motor. DIYers complete this repair in about 30 minutes with basic tools.

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
