Replaced micro switch, easy fix. Used stiff bladed putty knife to pry out bezel, then screwdriver to remove old, corroded and obviously non-functional micro switch. Electrical terminals also corroded; took a chance and just installed new one without doing anything about the corrosion. It's working so far. Here is a tip : there are 2 micro switches shown in the parts drawing, one for the ice dispensing and one for water dispensing without clear depiction as to which is which. The one with the straight blade actuator is for the ice dispenser, the hooked blade is for the water. I bought them both before I took it apart, I only wanted to do that once!
