How to Reset a Tripped Breaker, and When Repeated Tripping Is a Warning
A tripped breaker is a safety device doing its job. Resetting it is simple, but a breaker that keeps tripping is telling you something.
To reset a tripped breaker, unplug or switch off the devices on the dead circuit, open your electrical panel, find the breaker whose handle sits in the middle or “off” position, then push it firmly all the way to OFF and back to ON. That usually takes a couple of minutes. A breaker that trips again immediately, feels hot, smells burnt or buzzes is a warning: leave it off and call a licensed electrician. Never reset a breaker with wet hands, while standing in water, or if the panel looks damaged.
Why breakers trip
A circuit breaker protects the wiring in your walls from overheating. It shuts off power when:
- The circuit is overloaded: too many high-power devices running at once, such as a space heater, hair dryer and microwave on the same circuit.
- There is a short circuit: a hot wire touching a neutral or ground, often from damaged cords, appliances or wiring.
- There is a ground fault: current leaking to ground, common in wet areas. GFCI devices are designed to catch this.
- There is an arc fault: dangerous sparking from damaged or loose wiring. AFCI breakers are designed to detect this.
Before you reset
- Check for hazards. If you see smoke, scorch marks, melted outlets or smell burning, do not reset. Call an electrician, or 911 if there is fire or smoke.
- Stand dry. Make sure the floor is dry and your hands are dry. Use a flashlight if the area is dark.
- Reduce the load. Unplug or turn off appliances and lights on the affected circuit so they do not all restart at once.
Step-by-step: resetting a standard breaker
- Open the panel door. Only the door, never the inner cover (dead front); that cover protects you from live parts.
- Find the tripped breaker. Its handle will be in the middle position, all the way off, or out of line with the others. Some show a colored indicator. Panel labels help if they are accurate.
- Push it to OFF. Most tripped breakers must go fully off before they reset. You may feel a click.
- Push it to ON. Firmly, in one motion. Stand to the side of the panel rather than directly in front, as a general precaution.
- Restore devices one at a time. If the breaker trips when you plug in a specific item, that item may be faulty or too large for the circuit.
GFCI and AFCI devices
GFCI outlets
If an outlet in a bathroom, kitchen, garage, laundry room or outdoors is dead but no breaker is tripped, look for a GFCI outlet with TEST and RESET buttons. One GFCI can protect other outlets downstream, sometimes in another room. Press RESET firmly. If it will not reset, there may still be a fault on the line, or the device may have failed.
GFCI and AFCI breakers
Some protection is built into the breaker itself, with a TEST button on the breaker. Reset these the same way: fully off, then on. Some models show an indicator for the type of fault; check the panel or breaker maker’s documentation.
Test them regularly
The CPSC and UL have long advised testing GFCIs monthly: press TEST, confirm power goes off (a plugged-in night light helps), then press RESET. If it does not cut power, replace it. AFCI breakers have their own TEST button; follow the maker’s schedule.
Troubleshooting guide
| What happens | Likely cause | What to do |
|---|---|---|
| Trips when a specific appliance starts | Overload or faulty appliance | Move it to another circuit; have the appliance checked |
| Trips when several things run at once | Overload | Spread loads out; consult an electrician about circuits |
| Trips immediately on reset with everything unplugged | Short or fault in wiring | Leave it off; call an electrician |
| GFCI trips after rain or in damp areas | Moisture causing a ground fault | Dry the area; call an electrician if it continues |
| AFCI trips randomly | Arc fault, loose connection or device interaction | Have an electrician investigate |
| Breaker hot, buzzing or will not stay on | Failing breaker or connection | Stop; call an electrician |
When repeated tripping is a warning
One trip after you ran a space heater and a microwave together is ordinary overload. Repeated trips are not. Never:
- Hold a breaker in the ON position or tape it.
- Replace a breaker with a higher-amperage one. Breakers are sized to protect the wire; a bigger breaker on the same wire is a fire hazard.
- Remove the inner panel cover or try to repair wiring yourself unless you are qualified.
The Electrical Safety Foundation (ESFi) has homeowner guidance on overloads, GFCIs and AFCIs. Working inside panels is a job for a licensed electrician.
Appliance-specific tips
- Garbage disposals often have their own reset button on the unit as well as a breaker; see garbage disposal not working after reset.
- Electric water heaters use a double-pole breaker and a separate high-limit reset; see water heater not heating.
- Microwaves, toasters and space heaters draw a lot of current; avoid running them together on one circuit.
Label your panel
When things are working, map your circuits: turn off one breaker at a time and note what goes dark. An accurate panel directory makes future resets and repairs faster. Keep a flashlight near the panel; our basic tool kit for home repairs lists other essentials.
When to call an electrician
- A breaker trips again with nothing plugged in
- Burning smell, scorch marks, buzzing or a hot panel
- Flickering lights or warm outlets along with trips
- Frequent trips you cannot link to a specific load
- An older panel, or a panel you have concerns about
Bottom line
Reduce the load, push the tripped breaker fully off and then on, and bring devices back one at a time. Reset GFCIs at the outlet, test them monthly, and treat breakers that trip again, run hot or smell burnt as a reason to call a licensed electrician, not to keep resetting.
FAQ
Is it safe to reset a breaker myself?
Yes, for a single trip with no signs of damage, if you are dry and only open the panel door. Repeated trips need an electrician.
Why will my breaker not reset?
It may need to go fully off first, a fault may still be present, or the breaker may have failed. If firm off-then-on does not work, call an electrician.
How many times can I reset a breaker?
There is no safe number for repeated trips. If it trips twice with normal use, find the cause rather than resetting again.
Can a breaker go bad?
Yes. Breakers can wear out or become loose. Only a licensed electrician should test or replace one.
