Hi,
I got a buzzing problem with my low voltage ceiling light. It runs off a brand new volex low voltage dimmer switch but there's an annoying buzzing noise coming from the transformer. If the light is dimmed the noise gets much louder, but even on full power it's really irritating. Is there any way to fix this?
thanks
Replace the transformer with one that is suitable for dimming operation. This can also include suitable electronic transformers which will then operate silently.
Thanks Andy, but the transformer is built into the housing of the light so I can't replace it. Will have to remove the dimmer I guess..
Yes - get rid of the dimmer and replace it with an on/off switch! That's what I ended up doing.
Not a dimmable fitting?
Hmm, just tried it with a normal on/off switch and it's still buzzing! I could understand it if it was a cheap light, but it was =A360 at john lewis..
only solution is to replace the transformer. You dont need to physically remove the old one, just disconnect it and wire in a new one, which can sit next to the light on the plasterboard.

to be honest I'd rather send it back to john lewis than do that, but thanks anyway. btw, any idea what it is about this transformer that could be the cause?
While the fitting may be relatively expensive (market expectation and design), the transformer may well be a pretty low cost/quality component.
Does the label on the fitting say that it's dimmable?
