How to reset a GFCI outlet (2026)
Quick Answer
To reset a GFCI outlet, first unplug anything connected to it, then press the RESET button firmly. If it will not reset, or it resets and trips again, check whether there is a power outage, a tripped breaker, moisture in the outlet, or a fault in something plugged into that circuit. Stop and call a qualified electrician if the outlet is damaged, warm, wet internally, will not stay reset with nothing plugged in, or if you are unsure which circuit controls it.
Safety first
- Do not touch or reset a GFCI if the outlet, wall, floor, or your hands are wet.
- Do not remove the faceplate or outlet from the wall unless you are qualified and the circuit is safely isolated.
- Do not keep resetting a GFCI or breaker that trips repeatedly; repeated tripping means there is still a fault.
- Stop immediately if you see burning, melting, smoke, scorch marks, buzzing, or a loose outlet.
- If the outlet is outdoors or in a damp area, treat water ingress as a serious hazard and have it checked before reuse.
- Use only the TEST and RESET buttons and normal plug removal for homeowner-level troubleshooting.
When to call a professional: Stop and contact a qualified electrician if the GFCI is wet internally, damaged, loose, hot, buzzing, scorched, or smells burnt; if it will not reset after you unplug all loads and confirm the breaker is on; if it trips immediately with nothing plugged in; if a breaker also trips repeatedly; or if you would need to remove the outlet, faceplate, or work on wiring to continue diagnosing the fault.
Overview
A GFCI outlet is designed to cut power very quickly when it detects a ground fault, which helps reduce the risk of electric shock. Resetting one is often simple, but repeated tripping usually means there is an underlying issue that needs attention rather than repeated button pressing. Common causes include a temporary fault in an appliance, moisture, a tripped upstream breaker, loss of supply power, wiring problems, or a failed GFCI device. The safest approach is to unplug connected items first, check the main electrical panel for a tripped breaker, then try the outlet’s TEST and RESET buttons. If the outlet resets only when everything is unplugged, one of the connected devices may be at fault. If it still will not reset, the problem may be with the GFCI itself, another outlet wired through it, or the circuit supply. Because this is electrical troubleshooting, keep the work to simple user checks only. Do not remove the outlet faceplate or touch wiring unless you are qualified and the circuit is safely isolated. If the outlet shows scorch marks, buzzing, cracking, looseness, signs of water ingress, or repeated tripping with no load, professional diagnosis is the safest next step.
Who this is for
Homeowners and tenants who need to restore power safely to a GFCI-protected outlet or work out why it will not reset.
What you’ll need
- Good lighting
- Access to the consumer unit or breaker panel
- A dry hand and dry floor area
- The user manual for any recently plugged-in appliance, if relevant
Before you start
Make sure your hands are dry and the area around the outlet is dry. Unplug all appliances and chargers from the GFCI outlet and from any nearby outlets that may be protected by it. If the outlet is in a bathroom, kitchen, garage, utility area, outdoors, or anywhere damp, check for obvious moisture first and do not touch it if you suspect water has entered the outlet or wall.
Step-by-step
- 1
Unplug everything on the protected circuit
Remove plugs from the GFCI outlet itself and from nearby outlets that may have lost power at the same time. If you are not sure which outlets are downstream, unplug any appliances in the same room or area that stopped working.
Why: A faulty appliance or tool is one of the most common reasons a GFCI trips. Unplugging everything helps you tell the difference between a device fault and an outlet or circuit fault.
- 2
Check the breaker panel first
Go to the consumer unit or breaker panel and look for a breaker that is in a tripped position. Reset it according to the panel instructions. If there is a whole-area outage, wait for utility power to return before trying the GFCI again.
Why: Many GFCIs will not reset if the circuit has no incoming power. A tripped breaker or supply problem can make the outlet seem faulty when it is not.
- 3
Inspect the outlet without taking it apart
Look for visible damage such as cracks, discolouration, scorch marks, looseness, buzzing, or signs of damp. If the outlet is wet or damaged, do not press the buttons and do not use it.
Why: Physical damage, overheating, or water ingress can make the device unsafe to touch or reset and may point to a more serious electrical fault.
- 4
Press TEST, then press RESET firmly
If the outlet appears dry and undamaged and power is available, press the TEST button, then press the RESET button firmly until it latches. Some devices need a deliberate push. If it will not click in, do not force it repeatedly.
Why: Using TEST and RESET confirms whether the internal mechanism is responding as designed. If it will not latch, that usually means it has no supply, there is a fault on the circuit, or the GFCI itself has failed.
- 5
See whether power is restored
Check whether the outlet now powers a simple low-risk item such as a lamp or phone charger only if the area is dry and the outlet reset normally. Then reconnect other devices one at a time.
Why: Testing with one simple device helps you identify whether a particular appliance causes the trip, instead of immediately putting the full load back on the circuit.
- 6
Identify what makes it trip again
If the GFCI resets but trips as soon as a specific appliance is plugged in or turned on, stop using that appliance and check its cord, plug and manual. If it trips with nothing plugged in, leave it off and seek professional help.
Why: A repeat trip under no load points more strongly to outlet, wiring, moisture, or downstream circuit problems. A repeat trip tied to one appliance points to that appliance or its cord.
Why this works
A GFCI monitors the balance of current flowing out and back. If some current leaks to ground, which can happen through water, damaged insulation, or a person, it trips rapidly and cuts power. Resetting only works when the device has supply power and no fault condition is still present.
Common mistakes to avoid
- Pressing RESET over and over without unplugging appliances first
- Ignoring a tripped breaker and assuming the outlet itself has failed
- Trying to reset a GFCI that is wet, cracked, loose, hot, or making noise
- Assuming only the single outlet is affected when downstream outlets may also be protected by it
- Continuing to use an appliance that causes repeated tripping
Troubleshooting
RESET button will not stay in
Check for a tripped breaker, power outage, or another GFCI upstream. Unplug all loads and try again. If it still will not reset with power present, the GFCI or wiring may be faulty and needs professional diagnosis.
Outlet reset once, then tripped again straight away
Disconnect all plugged-in items and reset again. Reconnect devices one by one to find the one causing the trip. If it trips with nothing connected, stop using it and call an electrician.
No power at this outlet and others nearby
Look for a tripped breaker and check nearby bathrooms, kitchens, garages, utility rooms, outdoor outlets, or another location for a different GFCI that may control this circuit.
Outlet in a bathroom, kitchen, garage or outdoors keeps tripping in damp conditions
Let the area dry out and do not use the outlet until it is dry. If moisture keeps getting in, the outlet location, cover, box sealing, or device condition may need professional correction.
TEST button works but RESET still fails
That can indicate a supply issue, load-side fault, or failed device. Leave it off and have the outlet and circuit checked by a qualified electrician.
Breaker trips as well as the GFCI
Stop resetting both repeatedly. This can indicate a more serious short circuit, overload, or wiring fault and should be assessed professionally.

Alternatives
- If another GFCI appears to protect this outlet, reset that upstream device instead
- If a breaker with built-in GFCI protection has tripped, reset the breaker following the panel instructions rather than the outlet
Pro tips
- If several outlets lost power together, map which one is the controlling GFCI for future reference.
- After a successful reset, plug devices back in one at a time rather than all at once.
- Outdoor and garage outlets are especially prone to moisture-related trips.
- A GFCI that is old or unreliable may need replacement by a qualified person.
Legal & regulatory notes
Electrical work rules vary by country and sometimes by region. In many places, replacing outlets, altering wiring, or working in kitchens, bathrooms, outdoors, or other special locations may be restricted or require a qualified electrician and compliance with local electrical regulations. Check local building and electrical requirements before attempting anything beyond simple resetting and unplugging.
What this guide does not cover: This guide covers only basic user-level reset and troubleshooting of a GFCI outlet. It does not cover rewiring, replacing the device, testing with electrical instruments, diagnosing hidden circuit faults, local code compliance in detail, or work in flooded, fire-damaged, or otherwise hazardous conditions.
Cost considerations
A simple reset costs nothing, but repeated trips can point to a failing appliance, a worn GFCI, moisture problems, or wiring faults. Early diagnosis can prevent bigger repair costs and reduce shock or fire risk.

Why does my GFCI outlet keep tripping?+
Common causes include a faulty appliance, moisture, a damaged cord, a downstream wiring fault, or a failing GFCI device. If it trips with nothing plugged in, professional diagnosis is the safest next step.
Can a GFCI outlet go bad on its own?+
Yes. GFCIs contain internal components that can fail over time. If it will not reset, will not test properly, or behaves inconsistently, it may need replacement by a qualified person.
Do I need to turn off the breaker before pressing RESET?+
Not normally for a standard reset, but you should check whether the breaker has already tripped because a GFCI usually needs supply power to reset. Do not open the outlet or touch wiring unless the circuit is safely isolated.
Why are other outlets dead when only one GFCI tripped?+
A single GFCI can protect other outlets wired downstream of it. Resetting the controlling GFCI may restore power to all of them.
What if the outlet works after resetting but trips again later?+
That usually means the underlying problem remains, such as moisture, an intermittent appliance fault, or a wiring issue. Note what was plugged in and what conditions existed when it tripped, then investigate safely or call an electrician.
