GFCI Trips With Nothing Plugged In
A GFCI that trips with nothing plugged in may be reacting to moisture, a downstream wiring fault, an outdoor outlet issue, or a device that has gone bad.
Quick summary
If a GFCI trips with nothing plugged into it, the fault may still be somewhere on the circuit it protects. Moisture, damaged downstream outlets, outdoor boxes, or a worn-out GFCI can all cause trips even when there is no obvious load connected.
Common causes
Moisture in an outdoor, garage, bathroom, basement, or crawlspace outlet may be causing leakage.
A downstream outlet or device protected by the GFCI may have hidden damage or a ground fault.
An outdoor receptacle cover or weather-exposed box may be letting in water.
The protected wiring itself may have a fault that the GFCI is detecting.
The GFCI device may be failing and tripping even without a real load problem.
Safe checks homeowners can do
Unplug everything on the protected circuit and press reset to confirm the trip is not tied to a connected device.
Check outdoor, garage, bathroom, and basement outlets for moisture, cracked covers, or visible damage.
Look for other outlets downstream of the GFCI that may be dead or affected by the same device.
Notice whether rain, humidity, or outdoor use patterns line up with when the trips started.
When to stop and call an electrician
- Stop if the GFCI keeps tripping repeatedly with nothing connected.
- Stop if there is heat, a burning smell, visible damage, or any sign of moisture inside a box.
- Call a licensed electrician if the outlet is outdoors or in a wet area, or if you suspect the protected wiring may be damaged.
