My bathroom light consists of a 12" ring with an 8" ring inside. At
times it won't come on and at other times it works just fine. When it
fails, a heat lamp on the same switch does work. I have replaced both
rings but that doesn't help. I don't see a ballast or starter but I
haven't looked inside the fixture. What could the problem be?

In the canopy of the fixture is a "circleline" ballast for 1-32 watt T-12
and 1-20 watt T-12 lamp. It's probably not worth replacing, I'd get a new
fixture

Sometimes a florescent fixture acts like this because of a crappy ground.

May not be your problem, but it's cheap to check.

I agree with the two comments. 1. Possible bad ground issue. 2.
Ballast bad, above the parts you can see. I also agree that replacing
it may be the best idea, but remember that you will need a fixture
large enough to cover the area under the old one. That area likely is
now a different color than the rest of the ceiling.

If it's old, it could be a bad starter. If the switch is ON and the
ring won't light, lightly brush the ring using your hand--does this
work? Closely inspect contacts and connections for any corrosion,
evidence of sparking, or loose connections. Not sure how long you
want to troubleshoot, or just replace the fixture and be done with it.
