Easy repair. Figured how to remove it. (Unclipped it and then unplug the one wire). It was only one screw to remove access panel to get to wire harness.
Plugged in new ice maker. Replace access panel and rehung ice maker.
It took less than two minutes! I would have been very upset if I had paid for a service call for someone to come out and do that. The service call would have cost more than the new ice maker cost me.
