Light Fixtures that Stop Working

Electrical Question: I have a wall plug which I use for a table light. I attempted to turn the light on, but the light will not work.

  • I attempted to turn the light on, but the light will not work.
  • It was working earlier in the day.
  • The bulb is good and I reset the breaker for that specific plug and still got nothing.
  • Also I noted that two adjacent wall switches are not working either.
  • Other wall plugs and switches serviced by that breaker are working.

This electrical wiring question came from: Glen, a Homeowner from San Antonio, Texas.

Dave’s Reply:
Thanks for your electric wiring question Glen.

Light Fixture Electrical Circuit Problems

  • Light Switch and Electric Wiring
    • Glen, because you have stated that the electrical power is not working for more devices in this room the wall light switch should be tested. The wire splices located in the wall switch electrical box should be examined for possible loose or burnt connections.
  • Identify a Problem Wire Splice
    • In many cases such as this the problem may be caused by a faulty electrical connection or an electrical splice connection that has failed.
  • Checking Other Switch Locations
    • All electrical junction boxes associated with this circuit should be opened and examined as well until the problem has been located.
  • Repairing an Electrical Wire Splice
    • Burnt wiring or electrical wire splices will need to be repaired by removing the burnt areas of the wire and creating a new splice with a quality wire connector.
    • It is best to use a pair of pliers to twist the wires together gently and then trimming off the ends of the wire.
