If you take it apart there is a fuse for the larger lights, and they blow and are soldered in place on the circuit board. I tried to get the fuse out and it burned the wires to the board, so not easy to replace the fuse.
You need a new dimmer. I can't seem to find one with both switches in the dimmer??? One for the main light, one for the little decorative light.
