Sounds and vibration coming from the sealed ice maker assembly in top left side of freezer. 50 seconds knocking, 10 second pause, knocking resumes. When we unplug refrigerator and plug back in, the knocking stopped for 50 minutes before starting again. When I unplugged and let defrost for 2.5 hours, and then plugged back in, the knocking stopped for 77 minutes before resuming. Repairmen can't get here for 3 weeks. Any ideas?and vibrtion
Icemakers work by freezing the ice, then thawing the outside, rotating the ice out of the tray, and eventually dumping it in the bucket.
If the ice fails to release from the tray, the gears will make loud gridnging noise until you remove the ice from the tray.
Easiest way I've found to do this is to run a hair dryer pointed at the icemaker until the ice releases. Longer term, it seems that something is out of adjustment on your icemaker. You can also shut it off by pushing the bail up.
