how to remove dome light cover?
Greetings everyone. I'm getting ready to switch out the bulbs with LED's in the interior lighting fixtures, and have come across a small snag. Over the dining table is a dome light, and I cannot figure out how to remove the glass cover. There is a knob in the center which doesn't budge by rotating. I'm pretty sure this is how you remove the cover, but I'm unsure if only the knob should turn or if the round piece above it also should turn. I put a lot of pressure on it, and I don't want to break anything. Any ideas how to remove the dome?
