Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Ice maker not making ice.
• Water leaking at or near the valve.
• Slow or reduced water flow from the dispenser.

Check Before Replacing

• Confirm the refrigerator water shutoff is open and the supply tubing is not visibly kinked before attributing a no-water symptom to the valve.
• With the refrigerator unplugged, visually inspect the valve area, water-line connections, and electrical connector for loose connections, damage, or signs of moisture.
• After restoring water and power, observe the valve connection area for leaks while checking dispenser operation; discontinue use and shut off the water supply if a leak is found.
• Check whether the issue affects the dispenser, ice maker, or both; this helps describe the symptom but does not by itself diagnose the valve.
