I installed a dimmer switch in my washroom and it's making a buzzing noise. The more I increase resistance/rotate the dimmer clockwise, the louder it gets.
The humming seems to be coming from the common wire, not from the light fixture, live wire or from the mechanism within the dimmer itself.
The dimmer switch is advertised to hold up to 600w and I'm currently using 340w.
I tried to remove some of the lights and the noise persists.
The one thing I did notice is that the common wire isn't exposed or attached at the end, a section of the wire has been stripped at that's what the original switch was attached to.
How can I lessen or completely rid myself of this humming noise?
Edit: I've since replaced my Leviton rotary dimmer with a high end Lutron sliding dimmer and the problem still persists, at the same loud volume.
