A GFCI that trips at random with no weather or appliance correlation, or that fails its own TEST, may simply be worn or oversensitive. Persistent trips with nothing downstream, though, are a wiring fault for an electrician.

Where to stop. Drying a receptacle, fitting an in-use cover, and unplugging downstream loads are homeowner-safe. Replacing a GFCI or chasing a fault inside boxes means live conductors — if a GFCI keeps tripping with nothing plugged in, that's a wiring fault for a licensed electrician. This is general information, not a quote and not a substitute for a licensed electrician.
Electrical Fault Check provides general diagnostic information only. It is not professional advice, not a quote, and not a substitute for a licensed electrician. Do not work on live wiring. If you see smoke, sparks, burning smell, heat, shock, water exposure, or repeated tripping, stop using the circuit and contact a licensed electrician or emergency services as appropriate.
