How to Identify and Repair Problems with Fluorescent Light Fixtures
Electrical Question: I have fluorescent lighting in my kitchen and I have been having issues getting the lights to turn on when it is humid out.

This fluorescent light fixture is very frustrating!

• The bulbs are OK, in fact, I’m pretty sure they’re brand new.
• Do you have any suggestions on what this could be and how I can fix it?
• Anything you have to tell me would be a great help!

I look forward to your response. Have a great night!

Troubleshooting Checklist  for Repairing a Fluorescent Light Fixture

1. Lamp Pins and Sockets
   Make sure both pins of the lamps are in all the way in the sockets and the lamps have been rotated so the pins make connection with the socket contacts. At the base of each end of the lamp there are marks 180 degrees apart from each other which are indicators where one will point downward when the lamp is rotated into the correct position to make connection with the contacts in the sockets.
2. Ring Around Lamp Base
   Make sure both lamps are in good condition and do not have dark rings around one end. One bad lamp can prevent the other lamp from starting.
3. Damaged Sockets
   Check the lamp sockets. Lamp sockets can be damaged when a lamp is forced into place. If a lamp socket is cracked or broken then it will need to be replaced.
4. Ground Wire
   The fluorescent fixture enclosure must be grounded. If the ground wire has not been attached to the fixture housing this can cause the lamps to lighten up very dimly.
5. Fluorescent Light Ballast
   Never let fluorescent lamps burn out in the socket. This is a sure way of damaging the internal ballast which will require a new ballast and lamps, and a fixture ballast is the most expensive part which can cost around $20.00 dollars.
6. Lamp Starter
   Some older fluorescent fixtures require starters that can go bad. A starter has the appearance of a small round silver can which is usually found at one end of the fixture. Starters can burn out and require replacing. They require a slight twist to remove or install them.
7. Light Switch
   Every once and a while the wall switch may stop working and need replacing. Make sure to replace the wall switch with the same voltage and amperage as indicated on the original switch.
