Prep & safety

• Turn off the circuit breaker to the GFCI outlet before inspecting or working on it.
• Ensure all devices are unplugged from the outlet and nearby outlets on the same circuit.
• Wear rubber-soled shoes and use insulated tools to avoid electric shock.
• Check for visible signs of water or moisture near the outlet and its connected devices.

Step-by-step troubleshooting

1. Step 1: Unplug All Devices
   Do: Unplug all devices and appliances from the GFCI outlet and any downstream outlets.
   Observe: The outlet may reset and stay on if a faulty device was the cause.
   Means: A connected device is causing the trip.
   Next: Test each device individually to identify the faulty one.
2. Step 2: Reset the Outlet
   Do: Press the reset button on the GFCI outlet. If it stays reset, wait a few minutes to see if it trips again.
   Observe: The outlet remains reset without tripping.
   Means: The issue may be resolved temporarily or is not related to the outlet itself.
   Next: Proceed to Step 3 to test the circuit further.
3. Step 3: Test for Electrical Issues
   Do: Use a multimeter to test the voltage at the outlet. Ensure it reads around 120V.
   Observe: Voltage is outside the normal range or fluctuates.
   Means: There is a wiring issue or a problem with the circuit breaker.
   Next: Turn off the circuit breaker and inspect the wiring for damage or loose connections.
4. Step 4: Check for Water or Moisture
   Do: Inspect the outlet and nearby areas for signs of water or moisture, especially if it's in a kitchen, bathroom, or outdoor location.
   Observe: Visible water or dampness is present.
   Means: Moisture is causing the GFCI to trip as a safety measure.
   Next: Dry the area thoroughly and ensure proper waterproofing or sealing is in place.
5. Step 5: Inspect the Outlet and Wiring
   Do: Turn off the circuit breaker and remove the outlet cover. Inspect the outlet for burn marks, discoloration, or damaged wiring.
   Observe: Visible damage or signs of overheating are present.
   Means: The outlet or wiring is faulty and needs to be replaced.
   Next: Replace the GFCI outlet or consult an electrician for further inspection.
6. Step 6: Replace the GFCI Outlet
   Do: If the outlet is damaged or faulty, turn off the circuit breaker and replace it with a new GFCI outlet following the manufacturer's instructions.
   Observe: The new outlet resets and stays on without tripping.
   Means: The old outlet was the cause of the issue.
   Next: Test the new outlet with a GFCI tester to ensure it's functioning correctly.

Common causes

Parts you might need

When replacing parts for a GFCI outlet, ensure you match the correct specifications for compatibility and safety.

• GFCI outlet: match the amperage and voltage rating of the existing outlet
• Wire connectors: match the wire gauge and type (e.g., copper or aluminum)
• Outlet cover: choose a weather-resistant cover if the outlet is in a damp location
• Circuit breaker: match the amperage and type (e.g., standard or GFCI) if replacing the breaker
• Wire stripping tool: ensure it's suitable for the wire gauge used in your home
