Replaced the icemaker unit with a new unit. from ApplianceParts Pros. The replacement unit came with no cover or wiring harness with the expectation that the these items can be transferred from the old unit. The old unit's cover, wiring harness and shutoff arm could not be transferred. My Amana refrigerator is over 25 years old and the those items have been changed in the new unit. The other problem was the refrigerator did not have a model number plaque anywhere, therefore I had to do a search for the right parts to complete the repair. After two additional orders, I finally got the right parts and the ice maker is again producing ice "quietly".
