By far the most common problem is a loose wire connection at the switch itself, which is subject to constant on-off usage. Less commonly, a light bulb socket may go bad. If so, you will need to replace the socket.
Do light sockets wear out?
Sockets can fail because they simply wear out and no longer make a good connection with the bulb, they can overheat (usually caused by a high-wattage bulb), and they can short out. Fortunately, if a socket fails, you can take it out and replace it so your beautiful decorative fixture works like new again.
How do you fix a light socket that doesn’t work?
If a new bulb doesn’t work, turn off the switch or pull the plug (turn off the power, that is), and try bending up the little metal tab inside the bulb socket. These can get pressed in so far that they no longer touch the bulb’s electrical contact.
Do 3 way lamp sockets go bad?
You can test it by moving it to a working 3-way socket, but it’s very rare that both elements of a 3-way bulb will fail at the same time. But if part of it is coming on and the other part isn’t, the problem may be with the socket.
How do I know if my light socket is bad?
Touch the bulb at the bottom of the socket with the other lead. Record the reading. If it’s somewhere close to 120 volts, the fixture is good. If you get a reading of zero or one significantly less than 100 volts, the fixture is bad.
Why do light fixtures stop working?
If the light does not work with a new bulb, check whether the circuit breaker or fuse governing the fixture has tripped or blown. This often happens when a bulb burns out the moment it is turned on. … If the breaker fuse is not at fault, or if the bulb works but flickers or crackles, try cleaning the fixture’s socket.
How often do light switches go bad?
A light switch can last for 20 years or more. Light switches don’t necessarily wear out due to age because the internal springs are not under constant pressure. Light switches wear out due to repeated use or loose wire connections that cause them to overheat and short circuit.

Why do my 3-way bulbs burn out?
Habitually loose connections, either at the socket or with the wire connections, can burn out the bulb quickly, as well as cause flickering. These loose connections increase the electrical resistance and the heat passing through the filament of the bulb, which can shorten its life.

Can a light fixture burn out?
