## Electrical Troubleshooting & Repair questions

Straight answers to what Northern Virginia homeowners ask most.

![Zappy testing a circuit with a digital multimeter](/brand/zappy/zappy-electric-sandro-mascot-multimeter-troubleshooting-300.webp)

Why does my breaker keep tripping?

The most common causes are too many things on one circuit, a short, a ground fault, or a worn-out breaker. If it trips again right after a reset, stop and call an electrician.

Why did half my outlets stop working?

Often a GFCI outlet upstream has tripped, sometimes in another room, the garage or outside. Press RESET on every GFCI. If that does not help, a loose connection may be the cause.

Are flickering lights dangerous?

A loose bulb is not. Flicker in many rooms, or when large appliances start, can mean a loose connection or a neutral problem. Have it checked soon.

Is a warm outlet dangerous?

Yes, it can be. A warm or discolored outlet or switch can be a loose connection that is overheating. Unplug what you can, turn off that breaker if it is safe to do, and call an electrician.
