How long does a GFCI outlet last?
Updated August 2026
A GFCI outlet lasts 10 to 15 years, but here is the catch: its protection can quit long before the outlet stops delivering power. The ground-fault sensing circuit inside degrades with age and power surges, and a worn GFCI can reach the point where it still runs a lamp or charger yet no longer trips on an actual fault, the one failure that puts you at risk near water. That is exactly why you press the TEST button monthly. If pressing TEST does not cut the power, or RESET does not bring it back, the outlet has failed and needs replacing. A healthy unit trips within about one-fortieth of a second at a leak of just 4 to 6 milliamps. Each one costs $15–25.
Lifespan by type and situation
| Type or situation | Typical lifespan | Why |
|---|---|---|
| GFCI receptacle | 10–15 years | Protection can fade before the outlet stops working |
| GFCI breaker (in the panel) | 15–25 years | Protects a whole circuit and lasts a bit longer |
| Outdoor / damp-location GFCI | 7–12 years | Moisture and temperature swings shorten it |
| Older pre-2006 GFCI (no self-test) | Replace on sight | Lacks the auto-test and end-of-life lockout of newer units |
| Newer self-testing GFCI | 10–15 years | Locks out when it fails its own internal test |
| Downstream outlets on one GFCI | Same clock | One device can protect several ordinary outlets |
Signs yours is near the end
- Pressing TEST no longer cuts the power to the outlet
- RESET will not hold, or the button pops back out immediately
- The outlet is dead entirely, or a newer self-testing unit has locked itself out
- A blinking or solid fault light on models that have one
- Nuisance tripping that returns even with nothing plugged in
- A warm faceplate, scorching, or a burning smell at the outlet
How to add years
A GFCI only protects you if it can still trip, so testing is the whole game. Press TEST and RESET on every GFCI once a month; the power should die and come back cleanly, and skipping that 30-second check is how people end up with dead protection they never notice. If it trips for no reason or will not reset at all, sort out whether it is a real ground fault or a worn device before you assume the worst. Any GFCI that fails a test, is older than 10 to 15 years, or predates the self-testing designs is due for a straightforward replacement.
What it costs to replace: plan on $15–25 for the outlet ($120–200 if an electrician installs it). Replacing on your own schedule, before it fails, is almost always cheaper than the emergency version. The home maintenance cost calculator helps you set the money aside before it comes due.

How can I tell if a GFCI outlet has gone bad?
Test it. Plug in a lamp, press the TEST button, and the lamp should go dark; press RESET and it should come back. If TEST does nothing, or RESET will not hold, the protection has failed even if the outlet still powers devices, and it needs replacing. Newer self-testing GFCIs make this easier: when they fail their own internal check, they lock out and stop supplying power on purpose. A blinking indicator, a warm faceplate, or a burning smell are all reasons to swap it now.
How often should GFCI outlets be tested?
Once a month is the standard advice, and it takes under a minute per outlet. Press TEST to confirm the outlet cuts power, then RESET to restore it. Monthly testing matters because a GFCI's protection can fail silently: the outlet keeps working while the safety circuit no longer trips, so nothing tells you it is dead until you check. Newer self-testing models run their own checks automatically, but pressing the button yourself is still worth doing, especially on the outdoor and bathroom outlets nearest to water.
What does a GFCI outlet do that a regular outlet does not?
It watches for electricity leaking off the intended path, the kind of leak that happens when current finds a route through water or through a person. The moment it senses an imbalance of just 4 to 6 milliamps between the hot and neutral wires, it cuts power in about one-fortieth of a second, fast enough to prevent a lethal shock. That is why code requires GFCIs in kitchens, bathrooms, garages, basements, and outdoors. A standard outlet offers no such protection and will happily keep delivering power straight through a fault.
