The Water Valve Assembly is an OEM part for LG refrigerators. It is essential for controlling the flow of water to the ice maker and the water dispenser. This solenoid-operated valve responds to signals from the refrigerator’s electronic control system to accurately manage the release of water, ensuring efficient operation and reliability.

Symptoms of a bad Water Valve Assembly include:

  • The ice maker not producing ice or producing very small cubes
  • The water dispenser not functioning or dispensing a trickle instead of a steady flow
  • Water leaking from the refrigerator

Causes of a bad water valve assembly can stem from mineral deposits that clog the valve, electrical failures that impair the valve’s operation, or wear and tear from normal usage leading to leaks or malfunctions.

This OEM LG part is also compatible with Sears/Kenmore.

Note: Flow meter is not needed on all models, remove if necessary. Redesigned single valve replaces older dual solenoid valves. Wiring harness is included. Located behind the refrigerator.

My ice maker stopped filling the ice tray. But water on the door still works fine. If I pour water into the ice tray manually, it will freeze and dump the ice so it appears the ice maker is still working fine. The water inlet valve (AJU72992601) services both ice maker and water on the door. I did a reset on the ice maker by holding the button and I heard the water valve try to fill the tray but only a little water came out. When reset a 2nd time, I did not hear the water try to fill the tray. Is it possible the valve has become faulty only for the ice maker?

1 Answer

Steve, it is possible that the valve in the door has failed. With the door switch placed in an activated state and the valve in the door accessed, the 1/4 inch tube solenoid can be tested for 120 Volts AC after pressing the ice maker reset button. If voltage reaches the valve at the end of the forced harvest and water does not come through, the valve has failed. Unfortunately, the manufacturer has discontinued the valve 5220JB2008A / OEM17767754 for the model provided and it is no longer available.

Dave, No, I am sorry the only pressure adjustment would be the house hold pressure.

Hi there. I have a fairly new LG fridge where the water and ice share the same dispenser. It recently started to drip water, slowly by consistently, onto the tray. I spoke with LG and they walked me through several troubleshooting techniques on the fridge and nothing helped. In fact, they had me take out the water filter and put it back in and now instead of a drip it's a constant stream of water. It comes out through the dispenser and behind the dispenser lever. I was able to determine that when the ice tray fills with water, the tray overflows and the water starts running down the ice bin. Some gets inside the bin which freezes all the ice together and some runs down the outside of the bin. Nothing has changed as far as water pressure in my home. At least not to my knowledge. I don't know what could have happened to have caused my water pressure to change. It seems normal everywhere else. Is this possibly a water valve going out? If so, could you please recommend the correct part I would need based on my fridge model? Thank you so much!

Peggy, there are two valves in this model. The diverter valve MJX41869202 inside the bottom of the left door, and the main valve AJU72992601 in the back of the appliance. To identify if a valve has failed, the first step would be testing the main valve for voltage when the water dispenser is pressed. If there is voltage, the tubing going into the refrigerator can be removed, the port aimed into a cup/pitcher, and the dispenser pressed again to see if water comes through. If water does, the valve is good and the tubing can be put back in. From there, the diverter valve would need to be accessed (located behind the bottom door bin and access panel) so the incoming tubing can be removed and aimed into a cup. With the door switch taped down, the dispenser can be momentarily pressed to see if water comes through. If not, the filter ADQ72910911 would be the most likely cause of failure. If water does come through, the diverter valve would be the most likely cause of failure.

Matt W, Based on the information/model provided you would start by removing the dispenser cover ( usually a couple of screws from the bottom of the cover assembly). Our resources don't show the full breakdown, just the parts list.

Rusty, Check for proper pressure to the water valve from the house and then through the valve, you could have a restriction within the valve.

Kat If ypu are receiving voltage at the water valve when the dispenser is pressed then the water valve would need to be replaced as long as the filter and filter housing is okay.

Mark, You will want to test to see if there is 120 Vac getting to the water valve and if there is not then the icemaker would be the issue. If there is 120 Vac then the issue will be the water valve.

Hello David, You should first verify the water pressure to the unit is between 50 and 90 PSI. If this is good, the water valve AJU72992601 is the common cause of this issue. MJX41869202 should be changed at the same time as per the manufacturer.
