Quick answer
If a GFCI outlet won't reset, first turn off the circuit breaker. Press the reset button again. If it still won't reset, test the outlet with a multimeter. If no power is detected, the outlet may need replacement.
Confirm the symptom
- GFCI outlet has tripped and won't reset
- Reset button is pushed in but doesn't pop out
- Other outlets on the same circuit also don't work
- No power to devices plugged into the GFCI outlet
- Test button is non-functional

Prep & safety
- Turn off the circuit breaker for the GFCI outlet at the main electrical panel.
- Verify the power is off using a non-contact voltage tester before touching any wires.
- Ensure the area is dry to prevent electrical hazards.
- Wear rubber-soled shoes and insulated gloves for safety.
Step-by-step troubleshooting
- Check Circuit BreakerDo: Locate the circuit breaker for the GFCI outlet and ensure it is in the 'ON' position.Observe: Breaker is on and not tripped.Means: Power is available to the outlet.Next: Press the reset button on the GFCI outlet.
- Press Reset ButtonDo: Press the reset button on the GFCI outlet.Observe: Reset button pops out and stays out.Means: Outlet is functioning and has reset properly.Next: Test the outlet with a device or voltage tester.
- Test with Voltage TesterDo: Use a non-contact voltage tester near the outlet's slots.Observe: Voltage tester lights up or beeps.Means: Power is reaching the outlet.Next: Plug in a device to confirm it works.
- Check for Tripped OutletsDo: Look for other GFCI outlets on the same circuit that may have tripped.Observe: Another GFCI outlet is tripped.Means: Reset the upstream GFCI outlet first.Next: Reset the upstream outlet and try again.
- Inspect for Damaged WiresDo: Turn off the circuit breaker and remove the outlet cover to inspect the wiring.Observe: Loose, damaged, or frayed wires are present.Means: Wiring issue is preventing the outlet from resetting.Next: Tighten or replace damaged wires as needed.
- Test with MultimeterDo: Use a multimeter to test for voltage at the outlet.Observe: No voltage is detected.Means: The outlet may be faulty or the circuit is not receiving power.Next: Replace the GFCI outlet if no power is detected.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Faulty GFCI outlet Internal components may be damaged or worn out. | Common | Easy–Medium | GFCI outlet |
| Tripped upstream GFCI outlet Another GFCI outlet on the same circuit may have tripped. | Common | Easy | None |
| Loose or damaged wiring Loose connections or damaged wires can prevent power from reaching the outlet. | Sometimes | Medium | Wire connectors or replacement wires |
| Power supply issue The circuit breaker may be off or faulty. | Sometimes | Easy | None |
| Moisture or water exposure Moisture can trigger the GFCI to trip and prevent it from resetting. | Sometimes | Easy | None |
| Overloaded circuit Excessive load on the circuit can cause the GFCI to trip. | Rare | Easy | None |
| Ground fault in connected devices A device plugged into the outlet may have a ground fault. | Rare | Medium | None |
| Worn-out internal components Internal sensors or circuitry may degrade over time. | Rare | Medium | GFCI outlet |
Parts you might need
When replacing a GFCI outlet, ensure the new unit matches the old one in the following specifications:
- GFCI outlet: match the voltage rating (usually 120V) and current rating (typically 15A or 20A)
- Wiring configuration: match the number and type of terminals (e.g., line vs. load)
- Mounting dimensions: ensure the new outlet fits the existing electrical box
- Brand and model compatibility: if replacing a specific brand, match the model for consistent performance

Always turn off the power and double-check the wiring diagram on the old outlet before installation.
When to call a professional
- The outlet still won't reset after following all steps.
- You detect a burning smell or see visible damage to the outlet.
- You're unsure about the wiring or electrical system.
- The issue affects multiple circuits or the main panel.
- You hear unusual noises like buzzing or crackling from the outlet.
FAQ
Why won't my GFCI outlet reset?
It may be due to a ground fault, tripped upstream outlet, wiring issues, or a faulty outlet itself.
Can I reset a GFCI outlet multiple times?
Yes, but if it trips repeatedly, there may be an underlying issue that needs to be addressed.
How long do GFCI outlets last?
GFCI outlets typically last 10–15 years, but they should be tested monthly for proper function.
Do I need an electrician to replace a GFCI outlet?
If you're comfortable with basic electrical work, you can replace it yourself. Otherwise, hire a licensed electrician.
What's the difference between a GFCI outlet and a regular outlet?
A GFCI outlet monitors for ground faults and automatically cuts power to prevent electrical shock, while a regular outlet does not have this safety feature.
