The whole job took about 15 minutes. I used the tip of a butter knife to remove the dispenser panel from the door Started on the lower left and worked my way clockwise. It was a very simple process. The unit has 2 nearly identical micro switches. The gray one is for the ice dispenser, and the black one is for the water dispenser. My problem was a corrosion buildup on the wire contacts for the gray one. Most of my time was spent trying to slide the wire contacts off the old switch.Replacing the dispenser panel in the door was very simple.
