Ice maker didn't make ice.

First I did the diagnostics and thought the water valve wasn't functioning so I replaced that, but it still didn't make ice. So I went on line and found the first thing to fix should have been the module and motor assembly. It was a real easy fix because I had pulled the ice maker before to investigate what was wrong. I just removed one screw and disconnected the electrical. There were four screws holding the motor assembly on. So I put the new motor on and had ice in 30 mnutes.
