Outlet Warning Signs Worth Taking Seriously
Some outlet problems are easy to spot, like a cracked cover plate or a receptacle pulling away from the wall. Others are easy to live with for too long, such as plugs that slide out on their own or an outlet that only works some of the time.
Signs that an outlet should be checked include a receptacle or cover plate that feels warm, buzzing or crackling, scorch marks or discoloration, a burning smell, and sparks when something is plugged in. The U.S. Consumer Product Safety Commission’s home electrical safety checklist notes that unusually warm outlets may indicate an unsafe wiring condition and that loose-fitting plugs can cause overheating.
If an outlet is hot, smoking or sparking, stop using it and keep people away from it. Do not try to open it. If there is smoke or fire, leave the building and call 911.
