Test a GFCI correctly, distinguish loss of power from device failure, and know when replacement or deeper diagnosis is needed.

DIY Cost$18–$35

Professional Range$125–$250

Safety first: Stop when the work is outside your experience, requires opening energized equipment, involves structural uncertainty, or reveals heat, burning, active leaks or damaged wiring.

What to know

Press TEST and confirm the protected power shuts off. Press RESET and confirm it returns.

What to check

A GFCI may refuse to reset because it has no incoming power, an upstream device is tripped, LINE and LOAD are reversed, moisture is present, or a downstream fault remains.

How to approach it

Replace and investigate a device that is cracked, scorched, corroded, loose, buzzing, sparking or unable to hold a plug securely.

Common warning signs

Outdoor exposure, lightning, heat and repeated use can shorten service life. Regular testing matters more than guessing from age alone.

When to stop

If a new GFCI also will not reset, stop replacing parts and diagnose the circuit.

Common mistakes

Replacing parts before identifying the cause
Skipping measurements or manufacturer instructions
Using fasteners or materials not rated for the application
Closing the repair before checking for hidden damage

Tony’s Pro Tip

Before replacing a dead bathroom or exterior GFCI, check the garage, kitchen and other wet-area outlets. One upstream device may protect several locations.
