Problem with chandelier on dimmer switch?

If it is a 600 watt electronic dimmer they do this and it is because chances are the voltage fades out in it at the dimmer switch. Electronic dimmers vary from Style and make and they way they are made as well.

If this light has more then one light bulb and the dimmer is turned down rather low the voltage is dropping because of the dimmer and it simply is to low to control what you have. Again electronic dimmers do this if turned to low, I would say that the problem is just the dimmer being electronic not your wiring or light, as you stated it does fine of you turn it back up.

This is assuming you are using incandescent light bulbs.

Many dimmers do this not so unusual when on low.

Dimmer Switch Problems

If it doesn't function the way you expect it to, then Duh! you have a problem. Check the wattage of the chandelier, for compatibility with the dimmer switch. You don't have CFLs in the fixture, so don't worry your little head about that. Most have flame type bulbs (30 to 50 watts per), so you could be overloading the dimmer switch when you turn it down (increase the resistance in the switch). Explain this to the electrician that you have install the right switch. The code is meant to help prevent fires.

The dimmer switch may not be large enough for your chandelier. Standard dimmers are only 600 watts, you may need a larger one, like 1,000 watts. Cost becomes a factor $5.00 as to $39.00. The smaller one will burn out after a while. The newer fixtures today draw much more current than older ones (more bulbs or bigger bulbs equals more current which equals more watts).

Some lights aren't designed to be used with a dimmer switch.

It sounds like you are running a dimmer switch with CFL's which are compact florescent light, they're are not designed to be run with a dimmer. You could find "dimmable" CFL's which are expensive. If you keep running these CFL's with the dimmer you have the potential to damage the ballast and start a fire. I suggest you stop using them or replace them with regular light bulbs.

I would have an electrician check it out, you wouldn't want to be running the light with a short. You could burn your house down.
