I replaced the door switch. The video showed how to remove the switch and plug containing the wires. However, when I removed the switch, the plug disconnected inside the freezer wall and turned sideways. By using a couple of small screwdrivers I was able to maneuver the plug out, attach it to the new switch, and reinstall the switch. The switch removal and installation was easy. But, I think since the plug disconnected while pulling the old switch out, that perhaps the light issue was due to a loose connection and not the switch itself. At any rate, all works well now.
