When Fluorescent Lights Don't Work?

A dead fluorescent can be caused by lack of electrical power (tripped breaker or blown fuse), a dead or dying ballast, a dead starter or a dead bulb(s). Check for power first... then the starter (if applicable) and then the bulbs. When all else fails, the ballast should be replaced.

What do you do if your fluorescent light doesn't work?

If a fluorescent tube neither lights nor flickers when switched on, first check to see that the fixture is plugged in and that no fuse has blown or circuit breaker has tripped. If this does not help, try wiggling the tube gently in its sockets by rocking it back and forth and from side to side.
