I'm a tenant in an apartment and we're having strange lighting issues. We have a dimmable light switch panel in our lounge with 2 controls, controlling 4 LED spotlights each.
The dimmers make a buzzing sound when you turn it and hit either the minimum or maximum bounds, which is normal. If we turn it on and set it to the dimmest setting, after a while (could be a couple of minutes, could be 15 minutes), the lights automatically start getting brighter and brighter, and the light switch starts buzzing every 10/20 seconds. I assume the buzzing is because it's hit it's max range and something is trying to keep increasing it.
If we then turn it down again to the dimmest setting, it will eventually (could be a few minutes, could be 30 mins later) do the same thing. So we're basically unable to have our lights on dim!
We've had the light dimmer switch completely replaced the other day but it's just started happening again.
The electrician seems stumped. Any ideas?
