An electrical tester can help you find an electrical problem in your .
Some electrical problems can be attributed to human error while other problems are caused by faulty wiring or electrical device failure. There is usually a logical reason for an electrical failure and you can often locate the cause through process of elimination. If you need to troubleshoot a ceiling light that is not working, some basic knowledge of an electrical tester will help. While troubleshooting any electrical device, the electricity stays on. Caution is required.
Instructions
1. Check your home's circuit breaker at the main electrical panel. Make sure the breaker that supplies electricity to the ceiling light circuit is on. If the breaker is on, move to the next step.
2. Remove the ceiling light cover or shade to gain access to the light bulb. Remove the light bulb by turning counterclockwise. Check the filament inside the bulb to verify that the filament is still intact. If the filament is broken or burned, replace the light bulb. If the light bulb will still not light, move to the next step.
3. Test the socket of the light fixture. Use the two prong and insert one prong to the socket touching the contact at the center of the socket. Touch the other prong to the side of the socket or any other metal on the ceiling light. If the tester does not light, move to the next step.
4. Remove the ceiling light to expose the wiring in it's electrical box. Check for any loose wiring. Confirm that the black wires and the white wires in the electrical box are secure. Test for electrical power by placing one prong of the tester into the wire connector that holds the black wires together and touch the other prong to any metal on the electrical box. If the tester lights up, your socket may be damaged and need replacement. If the tester does not light up, move to the next step.
