Product review (5 stars): It works!
I installed this carefully and had to take a few small parts from the old one to make it right, which I expected.  These were the wire bail (the thing that turns it on and off), the motor cover and a small bracket on the bottom, which was bent on the new one.  It was a perfect fit and began making ice as soon as the freezer cooled down again.  I wasn't sure why the 'fridge had stopped making ice and I felt it was taking a chance replacing a part that might not be the problem.  Good call.  I think that what may have destroyed the old one was that we were overloading the freezer and food packages were physically interfering with the arms of the ice maker that eject the ice.  Now we resolve to keep the area around the ice maker clear.
