Ordered Ice Dispenser Actuator Arm, viewed video and replaced. Had to carefully study and replay video to make sure the door seal flap was depressed prior to and throughout the replacement of the actuator arm. Not sure the video put enough emphasis on this needed step. Would have saved me a few minutes, but overall was thrilled with the step by step video procedure. Also, the re-insertion of the water tube into its place in the reassembly process was personally a challenge for me. Forced me to pull any slack out of the tube as it exited the door before I could get close to re-insertion of the tube.
-- as an aside, my ice dispenser was not working since we moved in....3 years ago. So when I tested the ice dispenser function after re-assembly, the ice feed mechanism grabbed what was essentially a 10-pound block of ice that had been created over the years of idleness and tried to rotate it, knocking the freezer door open!. I should have checked the condition of the remaining ice in the container. As a result, I threw out the entire ice-mass and started fresh ice making.
