Heat or smoke near outlets, switches, wiring or the electrical panel.
Buzzing or crackling together with a burning smell raises concern for a loose or arcing connection. If the correct breaker can be reached safely, switch it off and leave the damaged equipment untouched.
Recent drilling, renovations or water leaks can help explain where hidden wire damage may have occurred. If the correct breaker can be reached safely, switch it off and leave the damaged equipment untouched.
Electrical odors can travel through wall cavities, making the strongest-smelling room different from the source. If there is active fire, heavy smoke or immediate danger, move to safety and call 911 first.
