LG Refrigerator Head Filter Assembly ADQ36011706 — Fixes Filter Leaks & Won't-Seat Failures

⚠️ This part (ADQ36011706) is no longer available from the manufacturer. It has been superseded by ADQ36011711. Limited new-old-stock may be available — contact us to confirm before ordering.

The LG ADQ36011706 Head Filter Assembly is the OEM filter housing and seating mechanism for LG refrigerators with internal water filtration systems. It replaces ADQ36011711 when fitment is confirmed by the appliance model number. When this assembly fails, the filter cartridge cannot seat and seal properly — causing leaks at the filter housing, reduced water flow to the dispenser and ice maker, or an inability to install a replacement filter.

Is This the Right Part?

Common Symptoms

• Water leaking from the filter housing or filter compartment
• Filter cartridge won't lock or seat properly in the housing
• Reduced water flow from dispenser or ice maker after filter replacement
• Filter indicator won't reset or filter error persists after installing a new cartridge

Check Before Replacing

• Confirm refrigerator powers on and cooling functions normally
• Verify water supply line is connected and water pressure is adequate
• Confirm a new filter cartridge has been installed or attempted
• Check that the issue is isolated to filter seating, housing leaks, or restricted flow — not a broader water system fault
