Tripping is a symptom, not the problem
A GFCI that trips is doing its job. The question is why current is leaking. Common causes include water in an outdoor box, a failing appliance heating element, damaged extension cords, or old wiring with deteriorating insulation. GFCIs do also wear out and can become overly sensitive or stop protecting altogether.
Because one GFCI can protect several outlets, a tripped device in a garage or bathroom can leave outlets elsewhere dead. Part of GFCI repair is mapping what each device protects. For step-by-step symptoms see GFCI keeps tripping.
What the work typically involves
Unplug and isolate
Remove loads and test whether the GFCI resets on its own.
Find the leak
Check downstream outlets, outdoor boxes and connected appliances for moisture or faults.
Repair or replace
Fix wiring faults, dry and seal boxes, or replace worn GFCIs.
Verify protection
Test trip function and confirm every protected outlet works.
Common reasons homeowners call
- Outdoor GFCI trips when it rains
- Bathroom GFCI trips when the hair dryer runs
- Garage GFCI trips with the freezer
- GFCI won't reset after a storm
- Dead outlets with no tripped breaker
Signs it is time to call an electrician
- GFCI feels warm or smells hot
- GFCI trips instantly on reset with nothing plugged in
- Burn marks on the outlet
- Water in outdoor outlet boxes
- Shocks from an appliance plugged into a GFCI circuit
Safety considerations
Don’t remove the protection. Never replace a GFCI with a standard outlet to stop nuisance tripping — that removes shock protection where you need it most. If a GFCI won't reset, leave the circuit off and call.
What an electrician will check
- GFCI age and trip function
- Downstream outlets and connections
- Moisture in outdoor or damp locations
- Appliances and cords on the circuit
- Line/load wiring correctness

Frequently asked questions
Either there's an active ground fault on the circuit, the GFCI isn't receiving power, or the device has failed. Unplugging everything and trying again helps narrow it down.
Yes. GFCIs have a limited service life. Newer designs self-test, but any GFCI that won't trip when tested should be replaced.
GFCIs protect everything wired downstream of them on the same circuit, which can include outlets in nearby rooms, garages or outdoors.
