Had some difficulty removing old unit, and thus installing new. I managed to figure it out from the video and from sticking my head into the 35 year old freezer on the side by side. I couldn't unscrew the ground wire because it was inaccessible and corroded, even with a stumpy screwdriver. I finally cut the ground wire and then figured out how to get the vibration mufflers off. I found that there were two ground connections, but I decided to leave enough wire to make a wire nut re-connection. It works fine so far after about two months. Quiet! Total time with all problem solving was about 1-1/2 hours.
