GFCI Keeps Tripping
Repeated GFCI trips may be caused by moisture, a failing appliance, downstream wiring issues, or a device that is simply worn out.
Quick summary
A GFCI trips when it senses an imbalance that could indicate current leaking somewhere it should not. That may be moisture, a damaged appliance, outdoor conditions, or a wiring issue downstream. One nuisance trip can happen. Repeated trips usually mean something on that protected circuit needs closer attention.
Common causes
Moisture in bathrooms, kitchens, garages, outdoors, or crawlspaces may be triggering the device.
A plugged-in appliance may have internal leakage and trip the GFCI even if it still seems to run.
Another outlet or device downstream of the GFCI may have a loose or damaged connection.
The GFCI itself may be worn out and trip too easily after years of service.
Safe checks homeowners can do
Unplug everything protected by the GFCI, then reset it and reconnect items one at a time.
Check nearby outdoor, garage, bathroom, or kitchen outlets for signs of moisture or weather exposure.
Test whether the GFCI holds with no load connected, which may help separate appliance issues from wiring issues.
Look for any recently added device, extension cord, or outdoor use pattern that started before the trips.
When to stop and call an electrician
- Stop if the GFCI will not reset even with everything unplugged.
- Stop if there is visible moisture inside a box, heat, a burning smell, or damage at connected outlets.
- Call a licensed electrician if the GFCI protects multiple outlets and you cannot isolate what is causing the trip.
