Product review (5 stars): Great replacement unit - just keep the extra parts
I am fairly handy and this was pretty easily installed in the freezer.  My previous one broke, and I used this for a replacement.  I only used the ice maker unit itself.  I kept all of the extra pieces for spare parts.  One tip, though, make sure that you install the proper sensor paddle on the bottom, or else the unit will keep making ice cubes even after the tray is full. (The dog love the overflow of cubes!)  Also, this unit make ice FAST.  My previous unit made a batch every 4-5 hours.  This one gives me ice every hour or so.  The price for this complete installation kit was less than the price just for a replacement ice maker....go figure.
