Hello, I have a flouresent light fixture above my sink.
When it is on it humms loudly.
I have replaced the tube and it has no starter.
What is causing the hum?
PS it is an old fixture


Like others said, its the ballast
The metal core pieces are vibrating probably due to a loose housing.
Some of the old ones that were held together with a metal piece that
goes around 3 sides can be quieted by squeezing that metal piece.
Otherwise, replace the ballast, but first price a new fixture. Many
times the fixture costs less than a ballast.

One could then donate the old fixture to someone who wouldn't mind the
humming, like a factory or a band without a rhythm section.
