What is a GFCI?
A GFCI, or ground fault circuit interrupter, is a safety device found in electrical outlets. It monitors electricity flowing in a circuit and will quickly shut off power if it detects a ground fault or imbalance. This helps prevent electric shocks and electrocution. GFCIs are required in areas where water may come into contact with electrical devices, like kitchens, bathrooms, laundry rooms, pools, etc.
Why won’t a GFCI reset?
There are a few reasons why a GFCI outlet may not reset after it has tripped:
Loose wiring
If the wires connected to the GFCI are loose, it may prevent the device from resetting properly. Check that all wires are securely attached.
Faulty GFCI
The GFCI may be defective. Older GFCIs can wear out over time. If the device is over 10 years old, it should be replaced.
Ongoing ground fault
If something plugged into the GFCI is causing a ground fault, like a faulty appliance, the GFCI will keep tripping. Unplug all devices on the circuit and try resetting – if it works, plug devices back one at a time to find the faulty equipment.
Moisture
Moisture can get into a GFCI outlet and prevent resetting. Make sure the area is dry before resetting.
How to reset a tripped GFCI
Resetting a GFCI outlet is easy. Just follow these steps:
- Unplug everything from the outlet.
- Use a dry cloth to remove any moisture on the outlet.
- Press the “Reset” button firmly all the way in until you hear a click.
- Plug in devices one at a time, waiting a minute between each one. If the GFCI trips again, the last device you plugged in is likely defective.
When to call an electrician
If a GFCI outlet won’t reset after multiple tries, it likely needs professional repair or replacement. An electrician can investigate the following issues:
- Faulty wiring connections
- Grounding problems
- Damaged GFCI
- Moisture in the electrical system
Replacing an older GFCI with a new one may also do the trick. Never ignore a GFCI that won’t reset, as it could indicate a larger electrical issue. Calling a qualified electrician ensures the problem is properly diagnosed and fixed.
Conclusion
GFCIs that won’t reset are a safety hazard and should be addressed immediately. Try basic troubleshooting steps like checking for loose wires, moisture, and faulty appliances. If the GFCI still won’t reset, contact a licensed electrician right away to inspect the electrical system and perform needed repairs. Replacing defective or aging GFCIs maintains proper protection against electric shocks. With the right maintenance, GFCIs can safely prevent electrocutions for years to come.
