Lighting – Dimmer switches & LED lights: Lights keep turning up to max and won’t stay dim

dimmer-switchledlighting

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?

I agree with previous poster to experiment with different bulbs. I have a different circumstance (older dimmer switch with track lighting) but the symptoms were similar for me. I was hearing a maddening low hum unless on full blast. I found that LEDs labeled as dimmable or regular incandescents work fine. It was an off brand LED that finally worked. Also consider that newly built does not always = correctly built.
