After searching internet for solution, came upon AppliancePartsPros.com They had some other postings with what seemed to be the same problem. I watched an easy to follow repair video on their site, bought the evaporator fan motor from them, which was less expensive than other places. Following the video exactly, a rather complicated job was broken down into simple to follow steps, and the refrigerator is now up and running and I saved at least $2800. Hip hip hooray.
