How to Successfully Replace a GFCI Outlet

How to Replace a Faulty GFCI Outlet: A Step-by-Step Guide


Ground Fault Circuit Interrupter (GFCI) outlets play a crucial role in ensuring safety and are mandated by electrical codes. They are required in outdoor locations and areas near water sources, such as bathrooms, kitchen sinks, or utility rooms with water sources. While GFCI outlets typically have a lifespan of 15 to 25 years, unforeseen issues can arise, necessitating a replacement.


If you experience a power loss in a GFCI outlet, the initial step is to locate the reset and test buttons on the outlet. If the reset button is slightly raised, press it to potentially restore power. However, if troubleshooting doesn’t resolve the issue, replacing the outlet might be the most effective solution.


Here is a comprehensive guide on how to replace a GFCI outlet:


Materials Needed:


A new GFCI outlet.

Insulated flat and cross-head screwdrivers.

Outlet tester – to verify correct connections.

No-contact voltage tester – to identify “live” wires.

Electrician’s wire strippers/pliers.

Steps for Successful GFCI Replacement:

Turn off the Power to the Outlet:

Switch off the power to the outlet by adjusting the corresponding breaker in the electrical panel.


Test the Outlet:

Use a lamp or a circuit tester to confirm the absence of power.


Remove the Outlet Cover/Faceplate:

Unscrew the faceplate screws and keep them in a secure place.


Remove the GFCI Outlet:

Unscrew the two long screws securing the outlet and carefully detach it from the box.


Safety First – Double Check the Power:

Utilize a no-contact voltage tester to ensure no remaining power in the wires. The tester will signal with a beep and light if power is still present.


Remove Wires from the Outlet:

Note the position of each wire for reference. Disconnect the wires, discarding the old outlet.


Connect the New Outlet:

Follow the instructions to identify which wire corresponds to each connector. Strip the wires according to the GFCI’s gauge and insert them securely into their designated holes. Ensure a slight tug to confirm secure connections.


Reinsert the Outlet:

Push the new outlet back into the box and secure it using the two long screws.


Replace the Faceplate:

Screw the faceplate back onto the outlet. Turn on the power and use an outlet tester to check for proper functioning—two amber lights should be displayed.


Final Test:

Press the GFCI test button; a click should be audible, and the outlet tester’s lights should go out. Press the reset button, and the lights should come back on.
