Hi. I have a square light fixture on the ceiling of my kitchen. It has been problematic since we moved in 10 years ago. It has 2 U-shaped fluorescent bulbs. When I turn it on, it usually works. But often, it doesn't, or it takes forever to turn on, or just one bulb will turn on. Both bulbs are good. So I just bought a new ballast, and the problem didn't go away. I'm out of options. Any thoughts as to the problem and how to fix it? Thanks.

You say both bulbs are good. How do you know? Did you just change them? Does this fixture use instant start ballast or does it need starters? Maybe you need new starters.

I know they are both good, because the one side works better than the other, and usually lights up the lightbulb, so I just exchanged them and the other u-light works as well. Where would the starters be? This seems like a simply mechanism. The wires come from the switch in the wall into the ballast, which then go to four pieces that house the nipples of the bulbs. Which is why it's frustrating, because it seems that it can only be the bulbs or ballast, both of which either have been replaced or work.

I replaced them a few years ago thinking that might help. If a bulb demonstrates that it is capable of lighting, I'm curious what could be wrong with the bulb to prevent it from lighting at another time.

Check to see if the fixture itself is grounded. It should be. I have found that grounds not connected to the fixture ground can cause erratic performance in fluorescent lights.
