Removed the door following the direction in the manual. Laid door on a card table for ease of handling. Removed to screws at top of door that appears to be for removing the handle. NOT!Removed the three screws at bottom of the door that are in the channel strip. This allowed the back half of the door to be removed and then it permitted access to the 4 screws (2 each side) that held the channel in place. Removed the channel, Did the cleaning and reversed the steps to install the new part and reassemble the door. Replaced the door. Looks like new.
