Random trips with no weather or appliance correlation can be a worn or oversensitive GFCI — replace it, but route no-load trips to an electrician.
Stop and call a licensed electrician or emergency services now if there's smoke, sparks, a burning smell, heat, shock, or water near the problem. Otherwise it's safe to answer the questions below.

Aging or oversensitive GFCI — random trips with no weather or appliance correlation can be a worn device

SAFE NEXT CHECKWith no weather or appliance pattern and a modest load, suspect the device itself. A GFCI that trips at random or fails its own TEST is worn — replace it. Persistent trips with nothing downstream 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.
Try the safe next check above. If it doesn't resolve it, or would mean working on wiring or a panel, stop and call a licensed electrician — don't replace parts on a guess. Open the full tool to change any answer for your exact situation, or try a related check below.

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.
