Reviewed instructions on YouTube. Removed storage box.Removed Philips head screw on either side of track. Lifted door and placed it on table. Using a flat blade screwdriver removed old gasket (it did not looked damaged). Pressed new gasket into groove in door. Replaced door onto track and replaced screws. Replaced storage box. No more ice buildup.
unfortunately my fridge stopped working. I purchased another but wanted to try and repair the old one. when ew one arrived, the old one was supposed to be put in garage but instead was hauled away. Had delivery return next day but they had as already removed and lost the handle screw for the bottom freezer and the screw that holds handle in place. ordered the handle screw and picked up the nut. very simple to install the screw and put handle back on.
replaced the ice maker with the new assembly kit, the longest time taken was to fit back the pull out door .. had to align the slots correctly and check that it slid back and forth easily.
