Step-by-step troubleshooting

1. Check for Tripped Breaker
   Do: Go to your electrical panel and locate the breaker controlling the GFCI outlet.
   Observe: The breaker may be in the 'off' position or partially tripped.
   Means: A tripped breaker indicates an electrical issue that needs to be reset.
   Next: If the breaker is tripped, turn it off completely and then back on.
2. Press the Reset Button
   Do: Press the reset button on the GFCI outlet firmly.
   Observe: The reset button should stay in and the outlet light may turn on.
   Means: A successful reset restores power and indicates the issue was temporary.
   Next: If the reset button stays in, test the outlet with a device.
3. Test the Outlet with a Device
   Do: Plug a working device into the GFCI outlet.
   Observe: The device should power on and the outlet light may turn on.
   Means: The outlet is functioning correctly and the issue was resolved.
   Next: If the device works, the issue is resolved.
4. Check for Power with a Multimeter
   Do: Use a multimeter to check for voltage at the outlet.
   Observe: The multimeter should read around 120 volts if there is power.
   Means: The outlet has power but the internal circuitry may be faulty.
   Next: If no power is detected, check the circuit breaker again.
5. Inspect the Outlet for Damage
   Do: Visually inspect the outlet for any signs of damage or burn marks.
   Observe: There may be visible damage or discoloration on the outlet.
   Means: Physical damage indicates the outlet needs to be replaced.
   Next: If damage is found, proceed to replace the outlet.
6. Test the Outlet with a Non-Contact Voltage Tester
   Do: Use a non-contact voltage tester near the outlet's slots.
   Observe: The tester should light up or beep if there is power present.
   Means: The outlet has power but the internal components may be faulty.
   Next: If power is detected but the outlet isn't working, proceed to replace the outlet.
7. Replace the GFCI Outlet
   Do: Turn off the power, remove the outlet cover, and disconnect the wires.
   Observe: The wires should be disconnected and the outlet removed from the wall.
   Means: Replacing the outlet can resolve internal faults or wiring issues.
   Next: Install the new GFCI outlet according to the manufacturer's instructions.
8. Test the New Outlet
   Do: Plug a device into the new GFCI outlet and press the test button.
   Observe: The device should power on and the outlet should trip when the test button is pressed.
   Means: The new outlet is functioning correctly and the issue is resolved.
   Next: If the outlet works, the issue is resolved.

Common causes

Parts you might need

When replacing a GFCI outlet, ensure the new one matches the old one in the following specifications:

• GFCI outlet: match the voltage rating (typically 120V) and amperage (typically 15A or 20A)
• Wires: match the wire gauge (14 AWG for 15A circuits, 12 AWG for 20A circuits)
• Mounting box: ensure it fits the size and type of the new outlet
