Acquired this fridge from some friends that were upgrading.  We tested in the garage before putting it in the kitchen.  The ice maker seemed to work fine (made 1/2 bin overnight), but since taking all the shelves, drawers and the ice maker out and doing a thorough clean and sanitize on the cabinet, drawers, and shelves, and putting back together, the ice maker is acting wonky.  Sometimes makes ice, sometimes not.  Sometimes I hear the ice drop and the water refilling, but sometimes the ice never drops.  I have tried to watch the cycle, and I have seen the ice get stuck at the top of the rotation, and it won't drop into the bin, so I clear that by hand and the cycle starts again; sometimes I hear the water filling the tray, but then the paddles never rotate that ice out, it just sits there.

Is this something that's easy to troubleshoot or a quick fix?  Should just get a new ice maker unit?  Will replacing the ice maker unit actually fix this problem?

I await the wisdom of the masters.
