Causes and Solutions of a Non-Working Light Fixture

How to Troubleshoot a Light Fixture that is Not Working – One of the bulbs burned out and I decided to try using an old CFL compact fluorescent light bulb that somebody gave me in its place.

Checklist for Possible Causes of a Non-Working Light Fixture

I hope you can help me! I have a ceiling light fixture that uses two 60 watt regular light bulbs.

I hope to be able to fix the problem myself.

Any advice you can give me will be MUCH appreciated. I’m so grateful that I happened upon your website.

Thanks for your electrical wiring question Nora.

How to Troubleshoot a Light Fixture that is Not Working

  1. Bad light bulbs. Purchase the correct replacement bulbs and install them.
  2.  A faulty wall switch. The wall switch should be tested and replaced if necessary.
  3. If a dimmer switch is being used make sure it is compatible with the type of light bulbs being that are installed.
  4.  Tripped circuit breaker. Check for a tripped circuit breaker, turn it all the way into the off position and then back into the on position.
