I have a 12-year-old Maytag Refrigerator/Freezer, (Side by Side), and just about a week ago the ice cube maker just decided to stop making ice. The water is still flowing from the door and the filter was changed recently. Any thoughts as to why this happened? My frig Model # was not on the pulldown list so I had to pick the closest available to get this far. Real Model # is MSF22C2EXB00.
