I have a light fixture in a closet that just stopped working.
Replaced all 3 bulbs (have also tested the 'old' ones, and they all
still worked anyway). Have tested each of the bulb 'sockets' with one
of those power testers, and all 3 'sockets' show that the light
fixture is getting electricity, but when I put bulbs in, they don't
light. I know the bulbs work, I tried them in a lamp. If you turn
the light switch on and off, nothing happens, but the power tester
thing will light up/make noise when the switch is in the on position
when each of the sockets are being tested. Make sense to anyone?!?!?!
Help I can't see anything in my daughters closet! Thanks!! Sarah
Sometimes (after turning OFF the circuit breaker to the light in
question), I have to take a small knife or other sharp object, and "scratch
clean" the center tab contact, so that it is shiny metal again, and makes
good contact. After that, my bulbs always work !!
Good Luck !!
It is extremely unlikely that all three sockets suddenly deformed enough
so that light bulbs won't connect to their contacts properly.
Most likely your "tester" is responding to a miniscule amount of current
coupled to it via interwire capacitance. But, that path will not support
enough current to light any kind of incandescent bulb.
You have an open circuit somewhere between your breaker panel (or fusebox)
and the light fixture.
Since the switch is probably near the fixture, and you tell us that it has
to be turned on to make the "tester" lightup/make noise, this tells me
that the open circuit is most likely in the neutral lead, and probably a
fair distance from the fixture.
I'm afraid you're goiung to have to get a professional, or at least
someone quite familiar with these sorts of problems in building wiring, to
find and fix the problem for you.
Good luck, and let us know what it turns out to be,
