GFCI Keeps Tripping? Troubleshooting Guide for Homeowners

A GFCI (ground-fault circuit interrupter) is the outlet with the TEST and RESET buttons, found in kitchens, baths, garages and outdoors. It trips when it senses current leaking to ground — a shock hazard. When it keeps tripping, it's usually catching a real problem, but sometimes it's just worn out. Here's how to tell which.
Why GFCIs trip
| Cause | Where it shows up |
|---|---|
| Moisture in the outlet or device | Outdoor, bathroom, garage and pool-area outlets after rain or humidity |
| A faulty plugged-in appliance leaking to ground | Any GFCI — often an old tool, heater, or worn cord |
| A downstream outlet with a wiring fault | The GFCI protects several outlets; the fault is at one of them |
| A worn-out GFCI device | Older GFCIs trip falsely or won't reset |
| Wiring/installation error | Mixed-up line and load terminals, or a shared neutral |
Work through it in order
Follow the steps below. Most GFCI trips trace to either moisture or one faulty device, both of which you can often find yourself. Stop and call a pro if it trips with everything unplugged and dry — that points to a wiring fault.
A note on outdoor and wet areas
Florence's humidity and storms are hard on outdoor GFCIs. A device that trips every time it rains usually has water getting into the box. The fix is a proper in-use weatherproof cover and, sometimes, relocating or resealing the outlet. Our outlet and GFCI installation service handles this.
Never replace a tripping GFCI with a regular outlet to "fix" the nuisance. The GFCI is preventing a shock hazard, and it's required by code in those locations. If it keeps tripping, find the cause — don't remove the protection.
When to call an electrician
Call a pro if the GFCI trips with nothing plugged in and no moisture present, won't reset at all, or you find multiple outlets involved. Those point to a wiring fault or a failed device that needs proper diagnosis. For repeated or panel-level issues, see our troubleshooting service or, for AFCI/GFCI breaker questions, breaker work.

Why does my GFCI trip every time it rains?
Moisture is getting into the outlet or box. Outdoor GFCIs need an in-use weatherproof cover; if water still intrudes, the outlet may need resealing or relocating. We can fix this.
My GFCI won't reset at all — what's wrong?
Either there's still a fault on the circuit, the GFCI has no power (an upstream breaker or GFCI is tripped), or the device itself has failed. Work upstream first, then suspect the device.
Can one GFCI protect other outlets?
Yes — a single GFCI often protects several downstream outlets. That's why an unprotected-looking bathroom outlet can go dead when a GFCI elsewhere trips.
Is it safe to keep resetting a tripping GFCI?
Testing a couple of times is fine, but repeated tripping means it's catching a real ground fault. Find the cause rather than forcing it. Call (843) 595-9236 if you can't.
