Repair the cause
A new faceplate cannot fix a wiring fault
A device can look worn and still be only part of the problem. We check its supply, connections and condition, then explain the repair. We may need to follow the circuit to another outlet, switch or protective device.
If several rooms or multiple circuits are affected, broader electrical troubleshooting may be needed. Tell us which outlets stopped working together and what was plugged in when it happened. Keep covers in place when sending photographs.
The CPSC identifies unusually warm outlets and switches, loose connections and damaged devices as conditions needing attention in its home electrical safety checklist. For smoke, active arcing or fire, keep away and call emergency services.
