Product review (5 stars): Replacement Ice Maker
After repairing the less-than-satisfactory ice maker that originally came in the less-than-satisfactory KitchenAid refrigerator at least a dozen times in 5 years, it finally quit completely when its shaft coupling broke.  This new icemaker is a factory replacement that you just have to plug in and slide in place and fasten with one screw from your old unit.  You also have to remove one piece from your old unit and attach it to the new unit with 3 screws - easy to do in 2 minutes or less.  It works perfectly right now - be sure and wait for at least 24 hours after you put it in for it to work - it has a temperature sensor and needs to get cold first.  It has at least one part that has been redesigned somewhat, that should solve one of the continuous problems I had with the original unit constantly jamming up.  Hopefully, this one will work and will last a long time.  Easy to install, fits perfectly.
