A Ground Fault Circuit Interrupter (GFCI) outlet is a critical safety feature in your home, designed to protect you from electrical shock. When it stops working, it’s often for a very good reason—it has detected a fault and has shut off power to prevent a dangerous situation. While sometimes a simple reset will fix the problem, a GFCI that won’t reset or keeps tripping is a clear warning sign. Here’s a guide to understanding why your GFCI outlets are not working and when to call an electrician.
What a GFCI Does and Why It Trips
A GFCI outlet continuously monitors the flow of electricity. If it detects even a tiny imbalance (as little as 5 milliamps), it immediately trips, cutting off the power in a fraction of a second. This imbalance, or “ground fault,” occurs when electricity is diverted from its intended path, often through a person or water, and is a life-threatening condition.
Common Reasons a GFCI Won’t Reset or Stops Working
- It’s Doing Its Job: The most common reason a GFCI won’t reset is that it is still detecting a ground fault somewhere on the circuit. This could be from an appliance that is plugged in, a loose wire, or a short.
- The GFCI Outlet Is Tripped Downstream: One GFCI outlet can protect other outlets downstream from it. If a GFCI outlet is not working, check every other GFCI in the house (including those in the garage or on the exterior) and reset them all.
- A Circuit Breaker Is Tripped: A GFCI will not work if there is no power to it. Check your main electrical panel to see if a breaker has been tripped.
- The GFCI Outlet Is Faulty: Over time, GFCIs can wear out and simply fail to reset. This can be caused by age, a power surge, or repeated ground faults. If you have confirmed that there are no ground faults on the circuit, the GFCI itself may need to be replaced.
- A Ground Fault in the Wiring: A short or fault in the wiring itself can cause a GFCI to trip repeatedly. This is a serious condition that requires a licensed electrician to diagnose and repair.
When to Call a Professional Electrician
While a simple reset can sometimes fix a non-working GFCI, a professional should be called if:
- The GFCI won’t reset and you’ve confirmed that all other GFCIs are reset and the breaker is on.
- The GFCI trips immediately after you reset it.
- The GFCI feels warm or you smell a burning odor.
- You suspect a ground fault in your wiring.
