Product review (5 stars): Works for KitchenAid Superba 42!!
My 17 year old 42 inch KitchenAid Superba built-in in refrigerator freezer had its ice maker stop working.  After reviewing the manual's troubleshooting, and how-to videos on replacement of the ice maker, I decided to buy this one an take a shot before incurring what would have likely been a $200+ repair cost.  I reviewed the instructions and the process for replacement.  Installation was a breeze.  All I needed was a screwdriver with nut driver attachments as well, and a utility knife to cut out a tab that was necessary for my particular install (this unit works on a variety of refrigerator - freezer models and brands).  Just make sure you thaw your freezer before replacing because sometimes (and as was the case with me), the old broken ice maker had caused the water in the feeder line to freeze at the very end due to it not working.

Oh, and keep in mind this thing does not start working right away.  Some people report 24 hours before it starts.  In my case, it started after about 4 hours, and seemed to produce ice slowly for the first 24 hours before going back to normal production.
