Genuine LG refrigerator filter drier assembly. The part filters refrigerant in the refrigerator's sealed refrigeration system and requires sealed-system service for installation.

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Freezer may be cold while the refrigerator compartment remains warm
• Uneven refrigerator temperatures or reduced cooling performance
• Cooling-system inefficiency associated with restricted refrigerant flow
• Visible oil residue or corrosion near the drier may indicate sealed-system damage, but does not by itself confirm drier failure

Check Before Replacing

• Confirm that the refrigerator has power and that the compressor and condenser fan are operating before considering sealed-system components.
• Record refrigerator and freezer temperatures and compare them with the appliance’s normal operating range; do not treat abnormal temperatures as proof that the drier is defective.
• Visually inspect the accessible drier and nearby tubing for corrosion, physical damage, or oil residue without opening or disturbing the sealed system.
• Have a qualified sealed-system technician evaluate refrigerant pressures and temperature difference across the drier when restriction is suspected.
• Do not cut, puncture, braze, evacuate, or recharge the refrigerant circuit as a consumer diagnostic step.

Pro Tip

Part Details

Key Features

• Genuine LG refrigerator filter drier assembly
• Filters refrigerant circulating through the sealed system
• Removes moisture and contaminants from the refrigerant circuit
• Helps reduce risks of corrosion, ice blockage, and compressor damage
• Includes a service-port-style drier configuration according to parts listing data
• Designed for installation within the sealed refrigeration circuit

Installation Notes

• This component is installed in the refrigerator’s sealed refrigerant circuit and is not a consumer-accessible filter replacement.
• Installation requires sealed-system service, including refrigerant recovery, circuit opening, leak checking, evacuation, and recharge by a qualified technician using model-appropriate procedures.
• Disconnect appliance power before service and follow the refrigerator’s service documentation and applicable refrigerant-safety requirements.
• Use the exact part and verify the appliance-specific service documentation before opening the sealed system.
• Because incorrect installation can cause leaks, restriction, moisture contamination, or compressor damage, professional installation is recommended.
