Troubleshooting Home Lighting Fixtures

Most of the time when a light in the home suddenly goes off, it is because the light bulb is blown and upon changing the bulb, the light works again. However, sometimes that is not the case and before you call in an expensive electrician or simply stop using a particular light, there are some things you can easily check yourself.

Check the Bulb

If the light bulb has blown out and you change it and the light still doesn't work, first, check the light bulb in another light just to make sure it is not a dud.

If it does work in another light socket or lamp, then you'll need to look closer at the fixture you are working on. Take the same bulb that you just discovered does work and try again, this time taking care to make sure the bulb is tightly screwed in the socket. If it still doesn't work, unscrew it and try again, this time making sure you are screwing the bulb in straight.

Now, this may seem funny but the ridges on some older light fixtures can become worn and it can actually be difficult to screw the light bulb in straight and not at an angle. While the bulb will actually fit in the socket this way, it is not making contact and won't work. If the bulb is screwed in tightly and straight and is still not working, check the tab, which is in the center of the socket.

If the tab is not making contact with the light bulb, the light won't come on. You may have to adjust it slightly in order for it to make contact with the bulb. You can most likely do this by gently pulling up on it but do not jerk it.
