Removing the motor and light assembly was easy. It was my first step before anything else. Four screws and a wire harness, piece of cake. Once the assembly was removed I got a good look at the motor and coupler connection. I found that the coupler moved freely by hand while the motor shaft did not. So I thought a fastening nut had loosened then fallen off the motor shaft. Went to 3 local hardware stores but I was unable to find a nut able to match the size and thread pitch of the shaft. (Note: the threads turn left handed.) Next, I did an internet search to find the part number for the nut and found that the coupler does not require a nut, it has one built in. At this point I knew I was on the wrong track. Now I suspected the threads on the motor shaft had stripped and the coupler was cross threaded. It was a little tricky to prevent the shaft from turning while I unscrewed the cross threaded coupler but with a needle nosed locking pliers I could reach behind the coupler to clamp the motor shaft and prevent it from turning while I unscrewed the coupler. I unscrewed the coupler in under 5 minutes and that includes finding my pliers. Sure enough the threads were stripped. Ordered a new motor and coupler. It got here very quickly Four days after starting this repair the ice maker was up and running great and this includes shipping time. These guys did a great job on helping me locate the parts via schematics, listed part numbers, and fast shipping.
