I just mounted a 5 light ceiling track light kit. I used this in my previous home with an on/off switch with no problems. After mounting this in my new home, on a rotary dimmer switch, I note that I hear a buzzing. Interestingly, this is NOT coming from the switch NOR the lights. Rather, the buzzing is inside the main unit/electrical compartment of the lighting kit. Any ideas what this is?? Thanks all!

Does it buzz when the dimmer is turned all the way up?

Need to know the make and model number of each the fixture and the dimmer, to confirm both are compatible. May be an electronic light fixture with a standard incandescent dimmer that are not compatible with each other, and need the correct dimmer to eliminate the noise.
