A GFCI (ground-fault circuit interrupter) outlet protects wet areas like bathrooms, kitchens, garages, and exteriors by shutting off power when it detects a ground fault. When it trips, downstream outlets on the same circuit often lose power too—even if they look normal.
Safe checks you can do first
- Press RESET firmly on the GFCI until it clicks. Then press TEST and RESET again to confirm it holds.
- Check other GFCIs in the bathroom, garage, or exterior. One tripped GFCI can protect multiple outlets.
- Inspect the breaker panel for a tripped breaker on the circuit—not just the outlet button.
- Unplug devices on the circuit and try RESET again. A faulty appliance can prevent reset.
- Look for moisture in outdoor boxes or near sinks. Dry the area before retesting if safe to do so.
Common causes
- Ground fault or leak: Water exposure, damaged cord, or failing appliance.
- Worn GFCI mechanism: Older outlets may not latch after years of use.
- Loose wiring: Back-stab connections or loose terminals cause intermittent trips.
- Overloaded circuit: Too many devices on one protected line.
- Incorrect downstream wiring: Line vs load terminals mixed up during DIY installs.
When to call an electrician
- GFCI will not reset after unplugging everything and checking the breaker.
- Outlet feels warm, smells burnt, or shows discoloration.
- Repeated trips with no obvious cause.
- You are not comfortable working inside the electrical box.
Final takeaway
Most GFCI issues start with a simple reset or a tripped upstream device. If power does not restore quickly, treat it as a safety issue and bring in a licensed electrician rather than bypassing protection.
