Outlet not working? Here's how to track it down
Quick answer
A dead outlet is most often caused by a tripped GFCI — frequently a different outlet on the same circuit — or a tripped breaker. Because GFCIs in bathrooms, kitchens, garages, and outdoors often protect several outlets downstream, resetting the right one can restore power to a whole group. Check nearby GFCIs and the breaker panel first. If a single outlet is dead and also warm, discolored, or scorched, stop and treat it as a wiring hazard for an electrician.
Common causes
- A tripped GFCI upstream on the same circuit (downstream outlets go dead until it's reset).
- A tripped breaker in the panel.
- A half-hot outlet that's controlled by a wall switch.
- A worn-out outlet or a loose 'backstab' wire connection.
- A burnt or heat-damaged outlet (a fire-risk situation).
What to check first
- Find and reset nearby GFCI outlets — bathrooms, kitchen, garage, and outdoors often share one.
- Check the breaker panel and reset any tripped breaker.
- Test surrounding outlets to map how much of the circuit is dead.
- See whether a wall switch controls the outlet (a 'half-hot' setup).
- Look and smell for scorching, discoloration, or heat at the outlet — a stop sign.
When it's urgent
An outlet that's warm, discolored, scorched, buzzing, or sparking is a fire hazard — stop using it and call a licensed electrician. Loose connections behind outlets are a leading cause of electrical fires, so don't keep plugging into a problem outlet to 'see if it works.'
DIY vs. call a pro
You can likely DIY
- Resetting GFCIs and breakers.
- Identifying a switch-controlled (half-hot) outlet.
- Mapping which outlets share the dead circuit.
Call a pro for
- Replacing a failed outlet or fixing loose/backstab wiring.
- Anything with heat, scorching, buzzing, or sparking.
- Older aluminum wiring or unclear circuits.

Get started freeFrequently asked questions
Why is my outlet not working but others are?
The most common reasons are a tripped GFCI somewhere on the same circuit (often in a bathroom, kitchen, or garage) or a tripped breaker. Reset nearby GFCIs and check the panel. If a wall switch controls the outlet, it may simply be switched off.
Can a dead outlet be dangerous?
A simply tripped outlet isn't, but one that's warm, discolored, scorched, or sparking is — loose connections and heat are a fire risk. Stop using it and have an electrician inspect it.
Why does one GFCI control several outlets?
GFCIs can protect everything 'downstream' of them on the same circuit. So a single tripped GFCI in a bathroom can kill outlets in other rooms, the garage, or outside. Finding and resetting that upstream GFCI often restores them all.
