How to Fix a GFCI Outlet That Won't Reset

A GFCI outlet that won't reset is usually caused by moisture, a wiring fault, or a damaged outlet that needs replacement.

1. Kill the Power First. Locate the circuit breaker that controls the GFCI outlet and flip it to the OFF position. This ensures your safety while troubleshooting. Use a non-contact voltage tester to confirm the outlet has no power before proceeding.
2. Eliminate Moisture Issues. Inspect the outlet for any visible moisture, dust, or debris. GFCI outlets are sensitive to water and will refuse to reset if moisture is detected. Dry the outlet thoroughly with a clean cloth and use compressed air to blow out any dust or debris from the outlet box.
3. Attempt the Reset. Turn the circuit breaker back on and attempt to reset the GFCI by pressing the RESET button firmly. You should hear a click and see the button pop out slightly. If it still won't reset, proceed to the next step.
4. Cut Downstream Connections. Turn off power again and remove the outlet from the wall by unscrewing the mounting screws. Disconnect the LOAD wires (usually marked and connected to terminals labeled LOAD). Cap these wires with wire nuts. This isolates the GFCI from any downstream wiring problems.
5. Pinpoint the Culprit. With only the LINE wires connected, restore power and try resetting the GFCI. If it resets successfully, the problem is in the downstream wiring. If it still won't reset, the outlet itself is faulty and needs replacement.
6. Install the New Outlet. If the outlet won't reset when isolated, replace it with a new GFCI outlet. Connect the LINE wires to the LINE terminals (usually the top pair) and reconnect any LOAD wires to the LOAD terminals. Ensure all wire connections are tight and properly positioned before reinstalling the outlet.
