Why does my home have buzzing outlets?

Buzzing outlets are usually caused by loose wiring connections, a worn-out receptacle, or a device plugged in that creates electrical harmonics. A loose connection causes arcing, which produces a buzzing or crackling sound. If your outlet is buzzing even with nothing plugged in, the issue is in your wall wiring. This is a fire risk. Turn off the circuit and call an electrician right away.

Why It Matters

Buzzing is a sign of dangerous arcing or loose connections. It should never be ignored, as it can lead to overheating and electrical fires.
