GFCI outlets — the ones with TEST and RESET buttons, usually in bathrooms, kitchens, garages, and outdoor areas — are supposed to be tested monthly. It takes about thirty seconds and it's one of the few pieces of electrical maintenance that's genuinely safe to do yourself.
How to Test It
- Plug in a small lamp or device — to the GFCI outlet, or one downstream of it, and confirm it's working.
- Press the TEST button — you should hear a click, and the power should cut off — your test device should turn off.
- Press the RESET button — power should return, and your test device should turn back on.
What It Means If It Fails
- TEST doesn't cut power — the GFCI has failed and isn't protecting that circuit anymore, even though it looks normal. It needs to be replaced — this is not a DIY outlet swap in most cases, since GFCI wiring and downstream protection need to be verified.
- RESET won't bring power back — could be the GFCI itself or a fault somewhere on the circuit — see our guide to why GFCI outlets keep tripping.
- You're not sure which outlets in your home are GFCI-protected — a licensed electrician can map your circuits and confirm you have GFCI protection everywhere current code requires it.
This is genuinely a homeowner-safe task — pressing buttons on an outlet's face is not the same as working inside a panel or rewiring anything. If a GFCI fails its test, that's the point to call a professional rather than replace it yourself.
