Electric Noise or Humming: When to Call An Electrician

electric noiseThere are many different things in your home that can lead to electrical humming or buzzing noises. The appliances and devices in your home are responsible for most of these noises. But, some electrical noises or humming can be very dangerous. Some common areas that can cause electric noise or humming include:

 

  • Main Hums: The normal humming noises that are produced from appliances, electronics, or audio equipment are called main hums. This electric noise is caused by the vibration of the motors or fans in these devices and is not harmful.
  • Light Fixture Humming: When your light fixture is buzzing or humming, it is either a loose wire, or more likely, an issue with the light bulb. You should first try to replace the light bulb. Some light bulbs, such as fluorescent bulbs, have ballast that vibrates when it needs to be replaced. If the humming stops after you replace the bulb, you do not need to contact an electrician. However, if the humming continues, call an electrician for diagnosis and repair.
  • Dimmer Light Fixture Humming: If a dimmer light fixture is humming, it is almost always caused by the light bulb. Dimmer switches work by quickly cutting the light on and off so it appears that the light is dimmer. This quick on and off cycle causes the light bulbs to hum. Replacing the bulbs with a different type of bulb, such as a rough service bulb, can fix this electric noise. Look for light bulbs that indicate directly on the packaging that they can be used with dimmer switches.
  • Outlet or Switch Humming: There are a couple of things can cause humming or buzzing noise that is coming from your outlet or switch. First, it could be a loose wire. Next, there could be a problem with the outlet or switch. Finally, there could be improperly grounded wires or too much load on the wires. Any of these issues could be a potential fire hazard, so it is important to call an electrician for repair. Do not try to fix the wiring yourself!
  • Circuit Breaker Humming: Humming at your circuit breaker can be very dangerous. A few different issues, all of which require attention by an electrician, can cause the humming noise. First, the circuit could be overloaded, which prevents it from shutting off when required. Next, a wire could be damaged or loosely connected to the breaker or to the breaker panel. Finally, there could be a potential electrical arc forming. If your circuit breaker is humming or buzzing, shut off all circuits immediately and call an electrician.
