Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Refrigerator water dispenser has little or no flow
• Ice maker does not fill or produces no ice despite a cold freezer
• Water leaks into the ice maker or ice bucket because the valve does not shut off fully
• Slow ice-maker refilling
• Water leaking from the refrigerator water-valve area

Check Before Replacing

• Confirm the refrigerator’s household water supply valve is fully open and the inlet supply line is not kinked.
• Check whether the refrigerator water filter is clogged or improperly seated, since restricted filter flow can mimic a valve problem.
• Inspect the water line to the ice maker for visible freezing or blockage.
• With the appliance unplugged and the refrigerator water supply shut off, inspect the valve, tubing connections, and surrounding area for visible damage or leakage.
• If qualified to perform electrical testing, check solenoid-coil continuity with a multimeter only after disconnecting power and water; an open circuit indicates a possible valve electrical fault, not a conclusive diagnosis.
