Is This the Right Part?

Confirm the complete model number before ordering. Similar ice maker assemblies may differ in mold size, ejector arm design, wire harness connector, or mounting bracket orientation.

Common Symptoms

• Refrigerator stops making ice entirely
• Ice maker produces very small, misshapen, or hollow cubes
• Ice maker fills with water but does not freeze or eject
• Ice maker runs continuously or does not shut off when bin is full

Check Before Replacing

• Verify the ice maker is turned on and the feeler arm or optical sensor is not in the off position
• Check the water inlet valve and water supply line for blockages or low pressure (<20 psi)
• Inspect the freezer temperature — it must be at or below 0°F (-18°C) for the ice maker to cycle
• Test the ice maker control board and thermistor before replacing the full assembly
