Hi! Three of my under cabinet lights are not working. We've replaced the bulbs with new ones, which we checked to make sure they worked, but no luck. The problem is, we can't find the transformer! The lights are installed under a false cabinet bottom, so you don't see any wires either inside or outside the cabinets. The switches for all lights are on one side of the kitchen. The 3 lights that are out are all in a row - one on one side of the sink, and two on the other on the other side of the sink - on the opposite side of the room from the switch. Anyone have any clues how I can find the transformer and fix them?
