Dimmer help


I am trying to replace two regular switches (side by side) with Dimmers. One of these switches (switch 1) is a two way switch that controls a series of recessed light and the other one is a one way switch (switch 2) that also controls another line of recess light.


Switch 1 has one red, one black and one white wire connected to it.

Switch 2 has two wires connected to it, both of them black wires.

I tried to replace switch 2 with a single pole dimmer that has 3 wires in teh back (2 black and 1 green). I connected the 2 black wires on switch 2 to the 2 black wires on the dimmer and since there was no ground wire, i left the green wire alone in a wire nut. But it did not work out, when I turned the breakers on, the dimmer did not work.

I know without a proper circuit diagram it's hard to tell, but I am wondering if anyone has any ideas on what I need to do to connect this successfully.

Thanks

Dimmer help


You connected it properly. Check the connections. Dimmers often have stranded wires and they can sometimes be difficult to get properly connected in a wirenut to the solid wire.
Or the dimmer could be defective.

Dimmer help


Thanks for the response, you are absolutely right, the wires were not screwed snugly enough in the wire nut. I really appreciate it.

Now I am trying to install a dimmer on a switch that controls a ceiling light. The switch in question, has one white wire and one black wire going into it. There is also a bare copper wire in the switch box.

The dimmer has 2 black and 1 green. I connected the black on the switch to the black on teh dimmer, white on teh switch to white on the dimmer and the green on the dimmer to the bare copper wire.

The lights came on but the dimmer (dimming function) did not work, also it was making a low buzzing sound. When I turn the dimmer on all the way, the lights would start flickering.

What am I doing wrong or is the dimmer bad?

Thanks

Are you trying to dim compact flourescents? Most CFL's are not dimmable.

I think you are right, these are CFLs. Why would they flicker though and why does the dimmer buzz?

Thanks
