If a GFCI outlet isn’t working, the problem is usually a tripped GFCI, a tripped breaker, a wiring issue, or a failed outlet—and most problems can be diagnosed in minutes.

FAQs
GFCI outlets are designed to shut off power when they detect a problem, so when one suddenly stops working, it’s often responding to a real electrical issue—not simply “going bad.” The challenge is figuring out whether the problem is a nuisance trip, a wiring fault, moisture intrusion, or a failed outlet.
In many homes, a single GFCI outlet protects several other outlets downstream, which can make the source of the problem confusing.
Before removing or wiring a GFCI outlet, turn off power at the circuit breaker and confirm the outlet is not live using a voltage tester.
Quick Answer
Start by pressing the RESET button firmly on the GFCI outlet. If it won’t reset, check the circuit breaker, look for other tripped GFCI outlets nearby, unplug appliances, and inspect for moisture or wiring problems. If the outlet still doesn’t work, the GFCI itself may need replacement.
Don’s Advice
Homeowners are often surprised to discover that the “dead” outlet is not actually the GFCI outlet that tripped.
A bathroom, garage, or outdoor GFCI may protect several standard outlets elsewhere on the same circuit. That’s why one dead outlet can sometimes trace back to a GFCI in another room entirely.
Quick Fix for a GFCI Outlet That Isn’t Working
Before doing deeper troubleshooting, try these quick checks:
- Press the RESET button firmly
- Check the circuit breaker and reset it if necessary
- Look for other tripped GFCI outlets nearby
- Unplug devices that may be causing the trip
- Check outdoor outlets and extension cords for moisture
Symptoms & What They Mean
The way a GFCI fails often helps identify the underlying problem.
| Symptom | Likely Cause |
|---|---|
| Won’t reset | Active fault, wiring issue, or failed outlet |
| No power at outlet | Tripped GFCI, breaker, or upstream outlet |
| Keeps tripping | Moisture, faulty appliance, or ground fault |
| Other outlets also dead | Downstream outlets affected by GFCI |
| RESET button feels loose | Worn or defective GFCI outlet |
| Breaker also trips | Possible short circuit or serious wiring fault |
Why a GFCI Outlet Stops Working
A GFCI outlet shuts off power whenever it detects unsafe current leakage. Sometimes the cause is obvious, but many failures require a little troubleshooting.
- Moisture or water exposure
- Faulty appliances or damaged cords
- Loose or deteriorated wiring
- A tripped circuit breaker
- Incorrect LINE/LOAD wiring
- A worn-out or defective GFCI outlet

Step-by-Step Troubleshooting
1. Press the RESET Button
Press the RESET button firmly until it clicks into place.
Some GFCIs require more pressure than homeowners expect, especially older outlets.
If the RESET button immediately trips again, the outlet is still detecting a fault somewhere on the circuit.
2. Check the Circuit Breaker
Look for a breaker that is tripped or sitting in the middle position.
Reset it by turning it completely OFF and then back ON.
Some GFCIs will not reset unless power is restored at the breaker first.
3. Check Other GFCI Outlets
Another GFCI outlet upstream may control the dead outlet.
Check nearby:
- Bathrooms
- Kitchens
- Garages
- Basements
- Outdoor receptacles
A single tripped GFCI can disable several protected outlets downstream.
For more about protected downstream outlets and proper LINE/LOAD wiring, see What Is a GFCI Outlet?.
4. Unplug Devices
Disconnect everything plugged into the outlet and nearby protected outlets.
A faulty appliance may be causing the GFCI to trip immediately.
Common offenders include:
- Hair dryers
- Space heaters
- Power tools
- Mini refrigerators
- Outdoor extension cords
5. Test for Power
Use a voltage tester or plug in a lamp to confirm whether power is present.
Some outlets appear “dead” when the problem is actually a loose connection or a partially tripped breaker.
6. Inspect for Moisture
If the outlet is outdoors or near water, moisture may be triggering the GFCI.
Check for:
- Rain entering outdoor covers
- Condensation inside outlet boxes
- Wet extension cords
- Bathroom humidity
- Water splashes near sinks
Allow damp outlets to dry completely before resetting.
Don’s Advice
Outdoor GFCI problems often become intermittent before failing completely. An outlet may work fine for weeks and then suddenly trip during humid weather or after rain.
If moisture-related trips keep returning, inspect the weather cover and gasket carefully. Small cracks or poor sealing can allow enough moisture inside to trigger the outlet.
7. Inspect Wiring (Power Off)
Turn off the power at the breaker before removing the outlet cover.
Look for:
- Loose terminal screws
- Backstabbed wire connections
- Burn marks or discoloration
- Damaged insulation
- Corrosion
- Incorrect LINE/LOAD wiring
Loose backstabbed connections are especially common in older homes and can cause intermittent power loss.

What If the GFCI Won’t Reset?
If the outlet won’t reset after troubleshooting:
- There may still be an active ground fault
- The outlet may be wired incorrectly
- The GFCI may have failed internally
- A downstream outlet may still have moisture or damage
GFCI outlets wear out over time and often become more sensitive or unreliable before failing completely.
Repair or Replace?
In many cases, replacing a worn-out GFCI outlet is the safest and most practical solution.
- Repair: Loose wiring, moisture problems, or minor connection issues
- Replace: Won’t reset, frequent tripping, visible damage, or age-related failure
Modern GFCI outlets are generally more reliable and less prone to nuisance trips than older models.
See Repair or Replace an Electrical Outlet for additional guidance.
When to Call an Electrician
Some GFCI problems require professional diagnosis.
- The outlet won’t reset after multiple attempts
- The breaker keeps tripping
- You see burned wires or melted insulation
- Multiple outlets are not working
- You suspect hidden wiring damage
- The outlet buzzes or feels warm
FAQs
Why is my GFCI outlet not working but the breaker isn’t tripped?
Another GFCI outlet upstream may be tripped, or the circuit may have a loose wiring connection.
Why won’t my GFCI reset?
This usually means there is still an active fault, moisture intrusion, wiring damage, or a failed GFCI outlet.
Can a bad appliance trip a GFCI?
Yes. Faulty appliances and damaged cords are among the most common causes of GFCI trips.
Do GFCI outlets wear out?
Yes. Over time, internal components can fail and require replacement, especially in outdoor or high-moisture locations.
