Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Little or no ice production when the ice maker otherwise cycles
• Water leaking near the ice-maker fill path
• Ice buildup or blockage at the fill-tube outlet
• Water flow entering the ice maker inconsistently or outside the mold

Check Before Replacing

• With the refrigerator unplugged and the water supply safely shut off, visually inspect the tube and its outlet for ice blockage, kinks, cracks, deformation, or disconnected tubing.
• Check for visible water residue or leakage around the tube connections after restoring the water supply, without touching energized components.
• Confirm that the tube outlet is aligned with the ice-maker fill area and is not obstructed by surrounding ice or parts.
• If the tube appears clear and intact but the ice maker still receives no water, check other portions of the refrigerator water system rather than assuming this tube is defective.
