Removed drip pan from ice dispenser. Removed two screws hidden behind drip pan to loosen bezel at bottom. Carefully lifted bezel off top hook to expose controller board cabling. Disconnected three connectors to control board behind bezel to remove bezel completely. Removed two (possibly three) screws to access the back of the ice chute mechanism. Removed broken paddle that just snaps in, being careful to capture paddle spring. Put paddle spring on new paddle and maneuvered spring-end hooks into the proper places as the paddle axles were snapped into place.
Reversed removal procedure to reinstall ice chute, controller cable connectors and bezel.
