Dimmer Switch Issues

A little while ago I went to switch on some recessed halogen lights (6 total on the same switch), which are on a dimmer switch, and at the moment they turn on I hear a POP, and 3 of the lights go off immediately. The other 3 on the switch work fine.

There may have been a spark at the switch as well, there was a spark somewhere, but I missed exactly where at the moment because I was startled.

First time i've had an issue with the lights in the 5 years i've lived here. I turned off the breaker to that room as a precaution, until I can look at this better tomorrow. Any ideas on a cause / where to start my search?

Thanks for any input.

Welcome to the forums.

Does the dimmer still work ? Usually after a jolt or short they're blasted.

If three lights are working and three are out it would indicate a problem either at the last working light or the first dead one.

Three burned out at the same time? Are any of the other lights in the house brighter or dimmer than normal?

Dimmer still works for 3 of the lights. The other 2 of the 3 light bulbs are fine, just one light bulb blew. Going to buy a new switch and see if that helps at all.

If the dimmer is still working..... how will replacing it change anything ?

Do you still have three non working fixtures on a circuit where three of the six are still working ?

A real stab in the dark, I doubt that is the problem.

Most likely the problem is in the light fixture whose lamp (bulb) burned out.

Unfortunately for most recessed lights, the box with the wiring connections is off to the side and not reachable through the ceiling opening using two hands. The reflector/shell of the light fixture usually slides down and out after a few screws are undone and perhaps a few springs are unhooked so you can see the connection box.

Well...... half dark anyway. Some are still working.

And a new dimmer won't fix the problem.
