Home is 60+ yrs-old. Kitchen was remodeled at some point in the last 5-10 years, but obviously I don't know who did the work as we only moved in last year. I see no other available wires to hook up to in the jct box, but there are three light fixtures (kitchen/kitchen/dining room) controlled by this jct box. No other light switches in the house work any of these three light fixtures. There are 5 recessed lights being operated by this light switch in question.

The three switches: one dimmer switch (the faulty one) operates 5 recessed lights in the kitchen, another dimmer switch operates 2 recessed lights in the kitchen, and the third switch is a simple on/off one the operates a single light in the dining room.

There's a bundle of wires in the back of the box. I'll have to see where they go/come from. The other two switches aren't connected to any green grounds, either.

The old and new switches are both rated at 600W. The 5 light bulbs controlled by this switch are 120W, each.
