Electrical systems usually give some warning before they fail. The trouble is that the warnings are easy to live with: a light that flickers now and then, an outlet that runs a little warm. Here is what the common signs mean and how urgently to act.
Call right away
- A burning or fishy smell with no obvious source. Overheated plastic and insulation have a distinctive odor. Switch off the breaker if you can identify the circuit and call an emergency electrician.
- Sparks, smoke or scorch marks at an outlet, switch or the panel.
- A buzzing or crackling panel. Arcing inside a panel is a fire hazard.
- Shocks or tingles from appliances, faucets or switch plates.
Schedule a visit soon
- Lights that flicker or dim when a large appliance starts. One room points to a circuit problem. The whole house can indicate a loose service connection, which is more serious.
- Warm outlets or switch plates. Dimmers run slightly warm. Regular outlets should not.
- Breakers that trip repeatedly. Our electrical repair team traces the cause instead of just swapping the breaker.
- Loose outlets where plugs fall out. Worn contacts arc. See outlet replacement.
Why these happen
Most electrical fires start at connections, not in the middle of a wire. Connections loosen over years of heating and cooling, and older systems have more of them carrying more load than they were designed for. That's why an older home with several of these symptoms benefits from an electrical inspection, and sometimes an electrical panel upgrade or rewiring.
What to do while you wait
Turn off the affected circuit, unplug what's on it and keep the area clear. If you see flames or heavy smoke, leave the building and call 911 first.
