I bought the door closer kit, watched the video on how to install and then replaced the cams on the bottom of the door. The video was a huge help. I had planned to take the door off but did not have to. I did take everything out of the door which helped. I had to lift the door a bit to get the screws to line up. The project took me longer because I spent some time going back to video and whatnot. Now the door snaps shut like it is supposed to. No more questioning if the food is spoiled!
