I did a search on the Internet and found the Appliance Parts Pros Q&A section. I ordered a main board based on the Q&A that I read. It was late Saturday night, so I could not talk to one of their very knowledgeable representatives. Upon further browsing, I found a Q&A where one light was out. I went back and, using a reflector, found that indeed one light was totally dead. I ordered a light and a spare. I stripped the plastic ends off a twist tie and inserted the wire into the dead LED connector, and all the lights came on. Early Monday I called and spoke with Sheila, who cancelled my main board order and confirmed what I really needed. The LED Cover can be gently pried out of the refrigerator wall using a small screwdriver. Unplug the connector wires, plug in the new device, and pop it back into the opening. Problem solved!
