Removing the old unit was difficult. The light was clearly designed for installation not for ease of repair. Since I was concerned about marring the surface of the refrigerator I used a paint scraper to get under the lip of the light and another smaller paint scraper to lift the unit away from the body of the refrigerator. It does not just "pop off". I eventually did get it free without any damage to the wall of the refrigerator. The repair was then very easy. There was a connector that was easy to separate allowing for the removal of the old unit without cutting any wires. The new unit had a mating connector, which easily connected to the old connector in the refrigerator. After some pushing I was able to install the new unit into the hole in the refrigerator. It does not exactly "snap in".
researched on line and found the wiring was in series and I the suggestion was to replace the first light in the series that was in the freezer. Ordered the replacement light board and took out the existing light and pooped in the new one. Lights now all work! 15 minutes at tops.
Lower the filter bottom housing to gain access to the filter. Unscrew the filter and install the bypass cap. Secure the lower filter housing to the top assembly.
