What you may be noticing
- The reset button will not stay in or pops right back out
- The reset button does nothing at all
- Other outlets in the bathroom, kitchen, garage or outdoors are also dead
- The GFCI's indicator light is off, red or flashing
Common possible causes
No power to the GFCI
Many GFCIs will not reset without power. A tripped breaker, or another GFCI upstream on the same circuit, can leave it dead.
Ground fault still present
If something on the circuit is leaking current, such as a wet outdoor outlet or a damaged cord, the GFCI will trip again immediately.
Worn-out GFCI
GFCIs have a service life. An older device may fail to reset or stop protecting even if it looks fine.
Line and load reversed
If a GFCI was installed with the incoming and outgoing wires reversed, many newer units will refuse to reset.
Moisture in an outdoor or garage outlet
Rain, humidity or condensation in an exterior box can cause a fault that keeps the GFCI from resetting.
Safe checks you can make
- Check the breaker panel and reset a tripped breaker once
- Look for another GFCI in the bathroom, garage, kitchen or outside that may be tripped
- Unplug everything from the GFCI and the outlets that went dead with it
- Press the reset button firmly one time with nothing plugged in
What not to do
- Do not hold the reset button in or tape it down
- Do not replace a GFCI with a regular outlet to get power back
- Do not use outdoor outlets in the rain while troubleshooting
- Do not open the outlet box or remove the device
Can you sort this out yourself?
Many GFCI problems are solved without any tools. A tripped GFCI in another room often powers several outlets, and resetting that one brings everything back. Unplugging a hair dryer, old freezer or damaged extension cord can clear the fault. If an outdoor outlet got wet, it may reset once dry. If none of that works, the GFCI may be failed or wired incorrectly, and replacing or testing it is a job for an electrician.
When professional help is appropriate
- The GFCI will not reset with nothing plugged in
- Several outlets remain dead after all GFCIs and breakers are checked
- The GFCI trips again the moment it is reset
- The device is old, discolored or warm
- The outlet is outdoors and stays wet or damaged
What an electrician typically checks
An electrician will confirm whether power is reaching the GFCI, check whether line and load connections are correct, and test downstream outlets and equipment for ground faults. Outdoor and garage boxes are checked for water entry and damaged covers.
The fix may be replacing a worn GFCI, correcting a reversed installation, repairing a wet or damaged outdoor box, or isolating a faulty appliance. For broader protection updates, GFCI and AFCI protection work can bring kitchens, baths and outdoor areas up to current expectations.
Keeping it from coming back
Press the test and reset buttons on each GFCI every month or so to confirm it works. Use in-use covers on outdoor outlets, which helps during Chattanooga's spring storms, and replace GFCIs that are older or fail to test properly. If yours only trips in wet weather, see GFCI trips when it rains.
