Dimmer, 3-way switches and LEDs

Our kitchen has 5 switches for the overhead lights. One of those switches has a dimmer, the other 4 are all just on/off switches. Prior to making changes, everything worked as expected.

We replaced all of the 9 overhead canister lights with LED "65 Watt", actual 13 Watt dim-able bulbs. After doing that, we started having flickering when the lights were on and periodic flashes when the switch was off. The switches still operated in the normal manner (on/off/dimming/different switches...). I found out then, that not all dimmers work with LEDs. I looked at a list of manufacturer tested LED dimmer switches and replaced the dimmer with one from the list.

Now, the flashes are gone (WOOHOO), the flickering is gone (WOOHOO), the dimmer switch works for on/off and dimming, but none of the other four switches seem to have any affect on the lighting at all (BOO).

Any suggestions? In case it matters, the other four switches are the kind that look like rocker switches, but when you press the rocker, they just click to change the state of the switch.

Did you mean Decora switches or are these low voltage switches? If you can please post a picture of the switch pulled out and the associated wiring. http://www.doityourself.com/forum/li...-pictures.html

If I have correctly interpreted your post you have several on/off switches that controlled various lights AND a dimmer that controlled different lights from the switches. You swapped out the incandescent bulbs for dimmable LED bulbs and the on/off switches worked as before but you had a problem with the dimmer. Correct?

You then replaced the dimmer and those lights now work fine but the lights controlled with the on/off switches now do not work at all. Is that correct?

All the on/off switches AND the dimmer are located in the same electrical box in the wall, correct?

I suspect that you have made a mistake on the wiring to the dimmer. Are all of these lights on the same circuit breaker or fuse? How many wires are connected to the dimmer? Have you tried turning the dimmer to full brightness and then trying the on/off switches?

The pictures that Ray requested will help.

I'm confused. What do you mean when you say that these switches "just click to change the state of the switch"?

Also, which of the 9 recessed fixtures does each switch control?

For a simple test, turn the dimmer on to full brightness. Now try the switches that were not working. Report back.

There are 9 recessed lights, all on the same circuit, all controlled a together by any of 5 switches spread around the room. Only one of those switches is a dimmer. The other four switches are remotes that just change the on/off state of the circuit. I believe that all of the remote switches just have two wires (Black and Yellow, not even a ground wire). The dimmer switch that was removed was a Lightolier ZP600. It had 3 wires (no ground). The new dimmer switch is a Lutron DVCL-153P. It is a dimmer listed as compatible to the Feit Electric bulbs on their web site. It has 4 wires (including the ground), a black, a red, a green, and a white/red striped.

The four remote switches are the kind that look like rocker switches sitting half way between on and off, but when you press the rocker, they just click to change the state of the switch. In the past, it didn't matter if the lights were on or off or if you pressed the "on" side of the switch or the "off" side of the switch. When the lights were on, if you pressed either "on" or "off", the lights would always turn off. When the lights were off, if you pressed either "on" or "off", the lights would always turn on.

Three-way and multi-location control is possible when the slide dimmer is combined with an unlimited number of preset remotes
You replaced a Lightolier dimmer with one made by Lutron. The Lightolier preset remotes that are still in place cannot communicate with the Lutron dimmer.

You will need to either install a new Lightolier dimmer that is made to work with your existing remotes, install Lutrin remotes (if they are available), or rewire the system to have true 3-way and 4-way switching.
