Product review (5 stars): Gets the job done...
I bought this to replace an icemaker in an Amana side-by-side refrigerator with the icemaker mounted along the back of the freezer portion.  It was a genuine part.  Like others say, this is more of a core icemaker, and you have to move some of the parts over from your old icemaker to this new icemaker.  It does not have the arm at all, so you have to move that over at a minimum.  Then I had to move over the small white plastic filler cup, because mine is a "back" fill and not a "side" fill.  I also had to move a small plastic bottom bracket.

So keep that in mind.  You will have to remove your old one, then lay it side by side with this new on, and start moving parts over from the old to the new.  Once you do that, it is then a simple plug in replacement.
