Order new part, took apart in door water and ice dispensing assembly
(After watching how to video on Appliance Parts Pro site) and
Replaced part. Only hard part was feeding water line back through hole. I had to tape a piece of string to guide it back through. Wish I knew how the pros do it - wish that had been highlighted in re-assembly video. Still $35 to fix a refrigerator and 30 minutes of my time is very sweet.
