ice maker made ice but pump ran too much

First I removed the front door by removing the screw on the top hinge. Then removed the upper hinge plate. This allowed removal of the top corner retaining screw. Removed screws at three other top corners. Now I could raise the top at a 45 degree angle to remove the controller cover. The controller was connected with several wire clips and held in place with two screws. Quick swap out and reverse order completion. Ice maker works like new!
