How to Reset a GFCI Outlet

A GFCI outlet that has tripped is one of the most common reasons an outlet — or a whole group of outlets — suddenly loses power. The fix is simple: press the RESET button. But there's a bit more to know to do it right and prevent it from happening again.

How to Reset a GFCI Outlet: The 30-Second Fix

Find the GFCI outlet. Look for an outlet with two small buttons labeled TEST and RESET — usually found in bathrooms, kitchens, garages, basements, and outdoor areas. The tripped GFCI may not be in the same room as the dead outlet it controls.
Unplug everything from the GFCI outlet and any outlets it protects. A ground fault from a plugged-in device will prevent the GFCI from resetting.
Press the RESET button firmly. You should feel and hear a distinct click as it locks into place. If it doesn't click, the button may not be fully engaging — press harder.
Test the outlet. Plug in a lamp, phone charger, or the Klein Tools RT250 outlet tester to confirm power is restored.
Plug devices back in one at a time. If the GFCI trips again when you add a specific device, that device has a fault — repair or replace it.

Why Did the GFCI Outlet Trip?

GFCI outlets trip when they detect a ground fault — a tiny imbalance between the current going out and coming back (as small as 5 milliamps). Common causes include:

A wet or damaged appliance cord — moisture creates a path for current to leak to ground
Water near the outlet — splashing in kitchens, bathrooms, or outdoors
A faulty appliance — damaged internal wiring leaking current
Overloaded circuit — less common, but possible if the GFCI is also a circuit breaker type
The GFCI itself is aging — older outlets (10–15+ years) can become overly sensitive or fail entirely

Which Outlets Does a GFCI Control?

A single GFCI outlet can protect multiple outlets downstream on the same circuit — even outlets in other rooms. This is why a tripped GFCI in the bathroom can kill power to outlets in the garage or hallway.

To find which outlets your GFCI controls:

Press the TEST button on the GFCI outlet
Use the Klein Tools RT250 outlet tester to check nearby outlets — any that go dead are on the GFCI's LOAD circuit
Press RESET to restore power when done

Common locations where a single GFCI protects multiple outlets:

One bathroom GFCI protecting all bathroom outlets in the home
A garage GFCI protecting outdoor outlets
A kitchen GFCI protecting countertop outlets on one side of the sink
A basement GFCI protecting utility room outlets

What If the GFCI Won't Reset?

If pressing RESET doesn't work — the button won't click, or it clicks but immediately trips again — the short version of what to check:

Make sure the circuit breaker isn't tripped
Unplug all devices and try again — a faulty device prevents reset
Check for moisture inside the outlet box
If the outlet is old (10–15+ years), it may have failed and needs replacement

How to Test a GFCI Outlet Is Working Correctly

After resetting, verify the GFCI is functioning properly:

Plug the Klein Tools RT250 outlet tester into the GFCI outlet — it should show correct wiring (two amber lights on most testers)
Press the TEST button on the outlet — the tester should go dark (power cut)
Press RESET — the tester should light up again (power restored)
If the TEST button doesn't cut power, the GFCI has lost its protective function and must be replaced

Test your GFCI outlets monthly — especially in bathrooms, kitchens, and outdoors. A GFCI that looks fine but doesn't trip on TEST is providing no protection.

When to Replace the GFCI Outlet

Replace the GFCI if:

It won't reset with no load and no fault
The TEST button doesn't trip it
It's 10–15+ years old
There are burn marks or physical damage

The Leviton GFCI Outlet 15A Self-Test (GFTR1-W) is a top-rated replacement — it automatically tests itself and uses an LED indicator to alert you if protection is ever lost. See: How to Replace a GFCI Outlet.

Frequently Asked Questions

Where is the GFCI outlet that controls my dead outlet?

Check bathrooms, kitchen (near the sink), garage, basement, and outdoor areas. The controlling GFCI is often in a different room than the dead outlet. Press TEST on each GFCI you find and see if your dead outlet loses power — that's the one controlling it.

How often should I test my GFCI outlets?

Monthly. Press the TEST button, confirm power cuts, then press RESET to restore. It takes 10 seconds and ensures your GFCI protection is actually working.

Can I reset a GFCI outlet from the breaker panel?

No — the GFCI must be reset at the outlet itself using the RESET button. Resetting the breaker only restores power to the circuit; it doesn't reset the GFCI's internal fault detection mechanism.

Why does my GFCI trip at night or randomly?

Random tripping is often caused by a faulty appliance that develops a ground fault intermittently (e.g., when it heats up), moisture that accumulates at certain times, or an aging GFCI becoming overly sensitive. Unplug devices one at a time to isolate the cause.

Quick Recap

Find the GFCI outlet (bathroom, kitchen, garage, basement, or outdoors)
Unplug all devices from the circuit
Press RESET firmly until it clicks
Test with an outlet tester or lamp
Plug devices back in one at a time
If it won't reset — check the breaker, unplug all devices, inspect for moisture, or replace the outlet

A GFCI outlet tester makes it easy to confirm your outlet is working correctly and identify which outlets are on the GFCI's protected circuit — a must-have for any homeowner.
