LG Ice maker Part AJU72992603, Replaces 850990 Refrigerator Water Inlet Valve Assembly
When the water inlet valve fails, your LG refrigerator stops delivering water to the ice maker and dispenser entirely — no ice, no water, and potentially a slow leak behind the fridge. Part AJU72992603 is the direct OEM replacement valve assembly, restoring full water flow to both the ice maker and dispenser in a single repair.

Before replacing the valve, verify your home water pressure is between 20–12 psi — LG inlet valves require a minimum of 20 psi to open fully. Also inspect the inlet screen on the back of the valve for sediment buildup; a clogged screen mimics valve failure. If pressure and screen are fine and the valve still won’t open, the solenoid coil has failed and the full assembly needs replacement. While you’re in there, inspect the water supply line for kinks or cracks to avoid a repeat call.
