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

Your LG refrigerator’s water filter is not seating correctly, leaking at the filter housing, or the filter indicator won’t reset. In LG refrigerators with an internal water filtration system, this is often caused by a failed or damaged head filter assembly. When it fails, the filter cartridge cannot seat and seal properly — resulting in leaks at the filter housing, reduced water flow to the dispenser and ice maker, or an inability to install a replacement filter. ⚡ Common failure point in LG refrigerators with internal filter systems. Part ADQ36011706 is the genuine LG OEM head filter assembly that restores proper filter seating, sealing, and water flow.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Refrigerator powers on and cooling functions normally
• ✔ Water supply line is connected and water pressure is confirmed
• ✔ A new filter cartridge has been installed or attempted
• ✔ ONLY problem is filter won’t seat, housing leaks, or water flow is restricted at the filter

Not sure? Send us your model number — we’ll confirm before you order.

🔧 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

✔ If these symptoms match, the head filter assembly is the most likely failed component.

✔ In most cases, replacing this assembly restores proper filter installation and full water flow immediately.
