Step-by-step troubleshooting
- Check Power SourceDo: Verify the circuit breaker for the GFCI outlet is on.Observe: Breaker is in the 'on' position.Means: Power is available to the outlet.Next: Try resetting the GFCI again.
- Dry the AreaDo: Ensure the outlet and surrounding area are completely dry.Observe: No moisture is present.Means: Water may be preventing the GFCI from resetting.Next: Press the reset button firmly.
- Reset the GFCIDo: Press the reset button on the outlet.Observe: Button resets and outlet powers on.Means: Issue was resolved.Next: Test the outlet with a device.
- Test the OutletDo: Plug in a device and press the test button.Observe: Device powers on and test button trips the GFCI.Means: Outlet is functioning correctly.Next: Monitor for recurring issues.
- Inspect for DamageDo: Check for visible damage, burn marks, or loose wires.Observe: No visible damage or loose wires.Means: Outlet is physically intact.Next: Check the circuit breaker again.
- Replace the OutletDo: Turn off power and replace the GFCI outlet with a new one.Observe: New outlet resets and functions properly.Means: Faulty outlet was the issue.Next: Test the new outlet thoroughly.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Moisture in the outlet GFCIs are designed to trip when moisture is detected. | Common | Easy | None |
| Faulty GFCI outlet Internal components may wear out over time. | Common | Easy–Medium | GFCI outlet |
| Tripped circuit breaker The breaker may have tripped due to an overload or short circuit. | Sometimes | Easy | None |
| Loose or damaged wiring Poor connections can cause intermittent tripping or failure to reset. | Sometimes | Medium | Wire connectors or electrician service |
| Overloaded circuit Too many devices on the same circuit can cause tripping. | Sometimes | Easy | None |
| Faulty device connected A defective appliance can trip the GFCI. | Rare | Easy | None |
| Wiring errors during installation Improper wiring can prevent the GFCI from functioning correctly. | Rare | Hard | Electrician service |

FAQ
Can I reset a GFCI without turning off the power?
No, always turn off the power at the circuit breaker before attempting to reset or repair a GFCI outlet.
Why does my GFCI keep tripping even when dry?
This may indicate a faulty outlet, wiring issue, or a defective device connected to the circuit.
How often should I test my GFCI outlet?
Test your GFCI outlet monthly by pressing the test button and ensuring it trips and resets properly.
Can I replace a GFCI outlet myself?
Yes, if you're comfortable with basic electrical work. Always turn off the power and follow manufacturer instructions.
What's the difference between a GFCI outlet and a regular outlet?
A GFCI outlet monitors electrical current and trips if there's a ground fault, providing protection against electrical shock.
