Unscrewed from the front of the refrigerator but due to the design of this particular model, the housing needed to be removed from the rear of the refrigerator. Unlike the video which shows and easy removal from the front, I needed to pull the refrigerator away from the wall, remove the back cardboard panel and squeeze the housing out over the drip pan. While not very difficult, be prepared to spend a little more time than shown in the video if you have a 106 model refrigerator.
The replaced part worked with no leaks but unfortunately when I turned the water back on, the water inlet valve began to leak requiring another part order (10.5 year old fridge). The water inlet valve is an extremely easy replacement. Once replaced, the ice maker and water dispenser are once again working well with no leaks.
