Light fixture problem

We recently had our dining room light replaced. Before that, everything worked fine but now the only way to turn it on or off is to unscrew the light bulb. It is on a dimmer switch that has 4 wires-black, white, red, and green. If we turn off the main breaker, everything else in the house shuts off except the light. Any ideas or suggestions? Nobody else can seem to figure out why everything else will shut off but the light.

Who did the work? Did you replace just the fixture, or did you replace the switch too?

This is a huge red flag. And it seems so unlikely too. Are you sure? Are you sure the "main" breaker is really the "main" breaker?

Miswiring lights so that they stay on all the time regardless of the switch is a common outcome when a switch loop is involved. Many people do not realize that connecting black to black and white to white is not always the correct algorithm. This is compounded by the fact that the fixture installation instructions always tell you to do exactly that. The only reliable algorithm when replacing a fixture is to connect the new one the same way the old one was connected.

We can help you sort this out, but we need more information. Start with my questions above. We'll have more questions after that.

My husband's "friend" did it. All he replaced was the fixture. If the main is what shuts off all power to the house then that's what it is. That can be off but the darn light stays on.

That's scarey... how did this guy install the new light without getting zapped??

Is there by any chance another breaker panel somewhere?

Those two statements are contradictory. If the light stays on when the switch is off, then the switch doesn't shut off all power to the house. I don't think you have found your main breaker.
