After watching the excellent video on how to replace the leaking water value module, ordered it from AppliancePartsPros.com. Repair was very easy using 1/4" nut driver and exacto knife (to trim the tubing). Refrig is back making ice again!
Trick is too watch the videos and identify which component need replacement, be it the ice maker itself, the water value module, or some other item. The videos are quite good, making it easy to figure out the problem and order the part needed.
