4 Electrical Issues That Can Cause a Buzzing Noise
Does a buzzing noise often disturb the peace and quiet in your home? This kind of sound is not something you should ignore, as it could result from a problem with your home's electrical system, which could be dangerous. Here are four possible causes of buzzing noises that should send you to the phone to call an electrician.
1. Faulty Connections
If the buzzing noise comes from an electrical outlet, a switch or from behind the walls, then it likely arises from a loose connection in your home's wiring. This connection problem could result from the wires degrading with age or from damage caused by rodents or other pests. A physical impact can also loosen the connections inside a switch or electrical outlet. Do not try to find or repair the loose connection yourself. Instead, call an electrician so they can make it safe.
2. Loose Front Plate
Sometimes, switches buzz simply because their front plate has come loose and is vibrating against the wall. If this is the problem, then simply tightening the screws could solve the problem. However, you must turn off the power before you carry out this fix to remove all possible risks of electrical shock. If you are not confident with this repair or you think the cause of the buzzing might actually be something deeper, then call an electrician instead.
3. Faulty Electric Meter
Sometimes, the electric meter that records how much power you have used in your home can develop a buzzing noise. You should never tamper with your own meter. Instead, call an electrician who can find the source of the buzzing and repair the meter for you. It is best not to put off this kind of repair, as problems with the meter can lead to you being overcharged for the electricity you use.
4. Old Fluorescent Lights
Fluorescent lights sometimes cause buzzing. You might also notice the light beginning to flicker. If changing the bulb does not help, then the problem must lie within the light fitting. Very old fluorescent lights use magnetic ballast to allow them to function, but this kind of ballast can make an irritating noise when the light is turned on. An electrician can remove the magnetic ballast to replace it with electronic ballast, which does not make a sound. Upgrading your fluorescent light fixtures should solve the buzzing, although it means that you'll from now on need to use modern bulbs instead of the old-fashioned ones designed to work with magnetic ballast.
