This guide teaches homeowners how to safely test and reset GFCI and AFCI devices in their homes. You’ll get step-by-step instructions, tips for spotting device failures, and guidance on when to call a licensed electrician. Created by the experts at Haines Electric, it ensures your home’s protective circuits are working properly.
GFCI (Ground-Fault Circuit Interrupter) and AFCI (Arc-Fault Circuit Interrupter) devices are your home’s first line of defense against electrical shock and fire hazards. Like smoke detectors, they only work if they’re functioning properly—and that means regular testing.
In this guide, we’ll walk you through when, why, and how to test your GFCIs and AFCIs, plus what to do if they fail.
Why Testing Matters
- Safety First: GFCIs protect you from shock, AFCIs protect you from fire.
- Code Compliance: The National Electrical Code (NEC) recommends regular testing.
- Peace of Mind: Knowing your devices work means you can trust them in an emergency.
How Often Should You Test?
- Monthly: Press the “TEST” button on each device.
- After Any Power Surge: Lightning strikes, tripped breakers, or outages.
- Before Heavy Seasonal Use: Pools, hot tubs, outdoor outlets before summer.
Tip: Mark your calendar or set a phone reminder so you don’t forget.
How to Test a GFCI Outlet
GFCIs are most common in kitchens, bathrooms, garages, basements, and outdoors.
Step 1 – Plug in a small device
Use something simple like a nightlight or lamp.
Step 2 – Press “TEST”
You should hear a click, and the device should turn off.
Step 3 – Press “RESET”
The device should turn back on. If it doesn’t, call a licensed electrician.
How to Test a GFCI Breaker (In Your Panel)
Some homes have GFCI protection built into the breaker panel.
Step 1 – Locate the breaker
It will have a “TEST” button.
Step 2 – Press “TEST”
You’ll hear a click, and the breaker handle will move to the middle or “OFF” position.
Step 3 – Reset
Flip the handle fully “OFF,” then back “ON.”
How to Test an AFCI Breaker
AFCIs are usually installed in bedrooms, living rooms, hallways, and other living spaces.
Step 1 – Identify the AFCI
Look for “AFCI” printed on the breaker.
Step 2 – Press “TEST”
It should trip immediately.
Step 3 – Reset
Move the breaker handle fully “OFF,” then back “ON.”
What If the Device Doesn’t Reset?
If a GFCI or AFCI won’t reset, it could mean:
- The device is faulty.
- There’s a wiring problem.
- There’s a persistent ground fault or arc fault.
⚠ Do not ignore a failed test.
A non-working device leaves you unprotected from electrical hazards.
Contact a licensed electrician immediately—especially if your home is older or has known wiring issues.
