Today I replaced our dining room's old 70s chandelier. When I opened it up I noticed pretty quick the rubber shielding on the lamps cords had been melting a bit towards the tips as it got all over my hands while taking down the old fixture. I just discounted it at age since it wasn't overly significant and the fixture had been up for years before we moved in a few months ago.
So I installed a brand new updated fixture and also replaced the existing single pole dimmer switch with the same model single pole dimmer I've installed elsewhere in the house.
Here's my problem: When I turn it on to full brightness, it works fine but there's a subtle buzzing noise coming from the switch and the fixture by the bulb(s)
When you dim it down it flickers.
Now, I've probably literally changed out a hundred fixtures over the years. The only thing different about the way I installed it was the new single pole dimmer had a ground wire I just hooked to the bare ground wire that was already there. Whereas the old switch didn't have one.
I'm pretty positive all the connections are fine and I used new screw caps on the twisted pairs.
I'm no electrician but it's not rocket science, however I could use some education from someone a bit more experienced than myself troubleshooting this weird behavior. If I have to pull it all back down and investigate a hint at what to look for in particular would be awesome.
EDIT ADDITION: Replaced it with a Leviton Cat. No. 6672-L "Universal" that's even has on the box advertising it for the bulbs in use. It still buzzes at the switch, the dimming is a little cleaner to a point before it flickers again. I can pull down the fixture and double check everything but I'm pretty sure it's not the culprit.
