Hired a repair professional. This is an expensive fridge so I wanted to repair rather than replace.
The estimated cost for the repair was quite high, but at least it was itemized. I went on-line and found Appliance Parts Pros, and bought the major plus one minor part from them. I arranged with my local repair guy to use the parts I bought on-line.
RESULT: I saved $370 by buying my own parts, probably could have saved more with a little more effort. Appliance Parts Pros was easy to deal with, quite helpful.
