Removed ice tray assembly and placed ice into plastic bag for keeping. Carefully looked over the unit and noted the location and function of the existing (broken part), to ensure proper installation of new part. I located the screws and nuts for removal of the part to be replaced. I made note the order of the disassembly. I placed new part in reverse order making sure not to over tighten. I reinstalled the ice tray assembly and placed about a cup of ice to test the function of the new part. When I was satisfied that it worked, I replaced the ice back into the tray.
