I removed all shelving. Used a cordless screwdriver with nut piece on end and took out nuts. Then had to CAREFULLY remove the mechanism that lets in cold air by gradation from the old end cap. Then put these parts on the new end cap. This took some thinking. Finally reset endcap and put unit back together again. Sucess and I am 61 and female.
