ice maker did not work. Water came in, however, unit woud not eject ice.

I unplugged the refrigerator, then I taped ice shield up to top of refrigerator and taped the little flap on the left side of the refrigerator to side wall then I unscrewed one screw on the right side that holds the plug cover, which was then removed. I then updid the little latches on the icemaker and pulled the old ice maker out far enough to unplug the connector, which was not easy, but did unplug. I then unscrewed the three screws with the nutdriver and attached the bottom cover to the new ice maker. I then slid the new icemaker far enough to connect the electrical connector, then slid the new icemaker in until it latched. I replaced the connector cover and untaped the two items that had been taped and pluged the refrigerator into the wall socket. The new icemaker has produced ice every since.
