This is a replacement ice maker assembly. The ice maker receives water from the water inlet valve and will freeze until ice cubes are formed. Once the water has been frozen the cubes will be ejected from the mold in to the ice bucket. The ice maker will continue the process until the ice bucket has reached the limit. If your ice maker is not making ice you may need to replace this part. Disconnect the power and water supply before starting your repair. This ice maker is a genuine OEM part. NOTE: This part has been updated by the manufacturer and does not include the cover, ice level arm or the wire harness. You can reuse those from the original ice maker.
