Quick answer: A GFCI outlet may not reset because it has no incoming power, the circuit breaker or another GFCI has tripped, moisture or a faulty appliance is creating a ground fault, the outlet has failed, or there is a wiring problem. Unplug everything on the affected circuit, make sure the area is dry, check the breaker, and then press the RESET button firmly. If the GFCI will not reset or trips again immediately, stop troubleshooting and call a licensed electrician.
A GFCI outlet that will not reset is doing more than causing an inconvenience. The outlet may be preventing power from returning because it detects a potential electrical shock hazard.
Premiere Electric helps homeowners throughout Cincinnati, Northern Kentucky, and the Greater Tri-State area diagnose GFCI outlets that are dead, will not reset, or repeatedly trip.
A ground-fault circuit interrupter, commonly called a GFCI or GFI, monitors the electricity moving through a circuit. If it detects electricity traveling along an unintended path, it quickly shuts off power.
GFCI protection is commonly found in locations where electricity may be exposed to water or damp conditions, including:
A GFCI receptacle usually has TEST and RESET buttons on its face. Some homes instead use a GFCI circuit breaker in the electrical panel to protect the entire circuit.

Several problems can prevent the reset button from staying in. Some are simple to check, but others require professional electrical testing.
Many newer GFCI outlets will not reset unless they are receiving power from the electrical panel. If a circuit breaker has tripped, a fuse has blown, or another device upstream has disconnected the circuit, pressing RESET will not restore the outlet.
This can make a properly functioning GFCI appear defective when the real problem is elsewhere.
A GFCI outlet and a circuit breaker perform different protective functions, but both can disconnect power from the same circuit.
Check the electrical panel for a breaker sitting in the OFF position or between ON and OFF. A partially tripped breaker can be easy to miss.

One GFCI can protect several standard outlets farther along the same circuit. The controlling GFCI may be in a different room or area.
For example, a dead outdoor outlet might be connected to a GFCI in the:
You may need to find and reset the upstream GFCI before the affected outlet will work.
A damaged appliance, extension cord, power tool, charger or outdoor device can cause a GFCI to trip. The outlet may refuse to reset while the defective item remains connected.
Common sources include:
A device can have an electrical fault even if it still appears to operate normally.
Moisture is a frequent cause of GFCI problems in Cincinnati and Northern Kentucky, particularly around exterior outlets, garages, basements, and patios.
Possible moisture sources include:
If you suspect water inside the outlet or electrical box, do not keep pressing RESET. Leave the outlet alone and have it inspected.

GFCI outlets contain internal electronic components that can eventually fail. Age, electrical surges, moisture, heat and repeated tripping can all contribute to device failure.
A failed GFCI may show one or more of these symptoms:
Replace a failed GFCI with the correct device for the location and circuit.
If the problem began immediately after an outlet was installed or replaced, the incoming and outgoing wires may have been connected to the wrong terminals. These are commonly labeled LINE and LOAD.
Modern GFCI devices may prevent resetting when they detect improper installation. Fixing this requires opening the electrical box and identifying energized wiring, so a qualified electrician should handle it unless the homeowner has the appropriate training and test equipment.
The visible GFCI may be functioning correctly and reacting to a problem at another outlet, fixture or connection that it protects.
Potential downstream problems include:
Finding these problems usually requires testing the entire circuit rather than replacing the first outlet that appears dead.
You can complete a few basic checks without removing the outlet cover or touching electrical wiring. Stop immediately if you notice smoke, heat, sparks, buzzing, melted plastic or a burning odor.
Unplug everything from the GFCI and any nearby outlets on the same circuit.
Remember to check for equipment that may be easy to overlook, including:
After unplugging everything, press RESET firmly. If it clicks and remains set, reconnect devices one at a time. If the GFCI trips when you connect a particular item, stop using that item.
Without removing the cover, inspect the outlet and surrounding area.
Look for:
Do not attempt to reset a wet, burned or visibly damaged outlet.
Search for another tripped GFCI in the kitchen, bathroom, basement, garage, laundry room, or outdoors. Press RESET only if the outlet and surrounding area are completely dry and show no damage.
If several outlets are dead, an upstream GFCI may be protecting them all.
Locate the electrical panel and look for a breaker that is OFF or sitting between ON and OFF.
To reset it:
Only reset the breaker once. If it trips again, leave it off and call an electrician.
If the outlet has power but the RESET button will not engage, try pressing TEST first. Then press RESET firmly until you feel or hear a click.
If RESET does not stay in, do not force it, tape it down, or hold it in place.
If the GFCI resets, plug in a lamp or another small device you know is working.
Then:
If pressing TEST does not disconnect power, or RESET does not restore it, you may need to replace the GFCI.
A GFCI is a safety device, so bypassing it can create a serious shock hazard.
Do not:
If resetting the device does not solve the problem, the next step is testing—not bypassing—the protection.
Call a licensed residential electrician if:
A licensed electrician can determine whether the problem is the GFCI itself, a connected device, an upstream power loss or damaged wiring elsewhere on the circuit.
Homes across Cincinnati and Northern Kentucky range from older properties with updated electrical systems to newer homes with multiple GFCI- and AFCI-protected circuits. Renovations, aging devices, outdoor moisture, and shared circuits can make a dead GFCI difficult to diagnose without proper testing.
