Product review (5 stars): Easy drop-in replacement
Even comes with different wiring connector adapters.  A few screws and the old one came out, new one screwed right into place.  I replaced the old one because it stopped working, but after removing it noticed that the non-stick coating was peeling off in places, so kind of glad it broke -- otherwise wouldn't have noticed.  IMPORTANT:  Keep the wire ice tray full lever detector from old unit -- this new one doesn't come with the wire lever.  Just snap out the old one and snap into new one.  One of the easiest home appliance repairs I've done.
