GFCI Outlet Keeps Tripping: Causes & What To Do
GFCI outlets are supposed to trip — that's how they protect you from shock. But one that trips constantly, especially with nothing plugged in, is telling you something.
Why this usually happens
- A plugged-in appliance has a ground fault (common with older hair dryers, space heaters, outdoor tools)
- Moisture inside the outlet or a downstream box (common outdoors or in bathrooms)
- A worn-out GFCI outlet that's become overly sensitive
- A wiring issue on the circuit it protects
What you can safely check yourself
- Unplug everything from that outlet and any downstream outlets, then reset
- If it holds, plug items back in one at a time
- Check for visible moisture, especially outdoors or in bathrooms after rain
When to stop and call a licensed electrician
If a GFCI trips instantly with nothing plugged in, or won't reset at all, that points to a wiring fault rather than a device — this needs a licensed electrician rather than a repeated reset-and-hope approach.
What not to do
- Don't bypass a tripping GFCI with a standard outlet
- Don't keep resetting it dozens of times expecting a different result
GFCI Outlet Keeps Tripping — common questions
Why does my outdoor GFCI trip every time it rains?
This usually points to moisture getting into the outlet, a connected junction box, or a light fixture on the same circuit — worth having checked before the next storm.
Can a GFCI outlet just wear out?
Yes — GFCI outlets have a limited lifespan and can become overly sensitive or fail to protect properly as they age. Replacement every 10–15 years is generally recommended.
