I have a fluorescent light fixture in my kitchen, which uses u-shaped tubes.
A few weeks ago they just stopped working. I could turn the switch on and there'd just be no light. Not flickering which I've read indicates a bad bulb. No buzzing sound, which I read means the ballast is bad either.
To make things weirder, a couple days ago I absent mindedly flicked the switch and the lights came right on! Today they worked fine when I got home from work, but after cooking I turned the lights off… when I tried to turn them on again an hour or so later they wouldn't come back on.
So what could be causing this?
EDIT: I should note that I installed new bulbs and they didn't work until the other day… and now they've stopped again.
