Quick answer
The short answer
Partial power loss means some lights, outlets, rooms, or appliances have power while others do not. It can come from a tripped breaker, failed GFCI, damaged circuit, panel issue, utility service problem, or a lost leg of power. If major appliances act strange, lights brighten/dim, or the panel sounds hot or buzzing, call an electrician.
What to know first
- Partial power loss is different from a full neighborhood outage and may point to a circuit or panel problem.
- Lights getting unusually bright or dim can be a serious warning sign.
- If resetting a breaker or GFCI does not fix it, the next step is electrical troubleshooting.
Partial power loss is a clue
When only part of a home or business loses power, the pattern matters. One outlet is a different problem than half the building, and a dead bathroom outlet is different from a panel that buzzes.
Start by noting which rooms, lights, outlets, and appliances are affected. That information helps a technician trace the issue faster.
Safe checks you can do first
Check whether nearby GFCI outlets need to be reset, look for a clearly tripped breaker, and ask neighbors if they lost power too. If a breaker trips again immediately, stop resetting it.
Do not remove the panel cover or touch damaged equipment. If you smell burning or see sparking, treat it as an emergency.
When the panel or service may be involved
If large sections of the house are out, 240-volt appliances stop working, or lights get bright/dim in unusual ways, the issue may involve the panel, neutral, meter, service equipment, or utility feed.
Those conditions need proper testing, not guesswork. Electrical ASAP can inspect the panel, circuits, and service-side symptoms and advise whether the utility needs to be involved.

Frequently asked questions
Why is only half my house without power?
It could be a panel, service, utility, or lost-leg issue. Because that can affect major loads and safety, have it checked promptly.
Can a GFCI cause multiple outlets to stop working?
Yes. One GFCI can protect outlets downstream. If it will not reset, there may be a fault or wiring problem.
Should I call the utility or an electrician?
If neighbors are also out, start with the utility. If only your property is affected, call an electrician.
