Buzzing dimmer switch

It's really loud when the light is turned full on.
Not sure how old the switch is - prob about 15 years.
If I replace it will it stop buzzing or is it just one of those things that happens with dimmer switches?

Mine buzzes too, but generally only when it's on a low dim. Just thought it was one of those things!

Got one too, on low dim buzzes.

What sort of bulbs are you using with it? Has the buzzing started since you changed to this type of bulb? I assume you're not still using incandescent bulbs, but that you were 15 years ago...

You probably don't have the right bulb, change it to one which says it is definitely for dimmer switches

Definitely a dimmer bulb - brand new today.
It's always buzzed iirc but it seems extra loud now - haven't used it really as previously it had an energy efficient bulb so didn't work with the dimmer switch.

I believe some bulbs are worse than others, and the noise can depend on whether the switch is dimming by varying voltage or duty cycle. If it's a duty cycle dimmer and the buzz is coming from the switch, I'd try replacing the switch. Less drastically, you could see if a different brand of bulb helps.

Sort of related article here.

I think they DO buzz, which is one of the reasons we don't have them (they're also very very energy inefficient...)

"Definitely a dimmer bulb - brand new today. "

Do you mean a dimmable LED, or do you mean an incandescent bulb with a filament?

Dimmable led

A dimmable LED is unlikely to be compatible with a 15-year-old dimmer that was designed for use with incandescent lights.

One of these probably is

I don't know enough about LED dimming. The maker of the lamp and the dimmer may mention what type they are.

Thank you - I'll do some research over the weekend.

Mine does this. I was so concerned I called an electrician. He told me they are meant to buzz a bit, I can't remember exactly what he said but he said totally safe.

Have just asked my electrician husband for you and he says that it could mean the switch is on it's way out and needs replaced. Something to do with a coil inside or something. So if you've had the switch a while might be worthwhile replacing it.

Great - thank you - I'll find a replacement to be on the safe side!

We did a lot of research into dimmers for our recent extension. Went for Varilight V-pro which is designed specifically for dimmable LED; they work perfectly for us and there's no buzzing at all.
