What is a Ground Fault Circuit Interrupter?

A Ground Fault Circuit Interrupter, also known as a GFCI breaker or outlet, is an electrical device that protects homes and businesses from potential electrical shock. A GFCI-protected outlet works by shutting off power when a ground fault or leakage current is detected.

How To Reset A GFCI Outlet

If you are experiencing problems with your GFCI circuit, the first thing you should do is a simple test and reset. The TEST and RESET buttons are typically located in between the two plug-in slots. In many outlets (but certainly not all), the TEST button is typically black while the RESET button is red. To test your GFCI outlet, simply plug in a small device like a nightlight or hair dryer and turn it on. Then press the TEST button on the outlet. Ideally, the device should turn off, indicating that the GFCI is working properly. If the device does not turn off, the outlet may be faulty.

The next step is to reset the GFCI. Start by unplugging any appliances that may be sharing the same circuit as the outlet. Then, locate and press the RESET button firmly. You should hear a click when you do this, which indicates that the outlet has successfully been reset. 

If the outlet does not reset, check your circuit breaker to ensure there are no tripped breakers and try again. If the problem persists, it may be time to call a Carrollton electric professional from Lex Air for further inspection and repair.

Common Signs That Your GFCI Outlet Is Not Working

There are a number of things that may signal your GFCI outlet is not working properly. Here are some of the most common:

  • No Power Output – There are a few reasons your GFCI outlet may not be giving off power to connected devices, including a tripped circuit breaker, a malfunctioning outlet, or underlying wiring issues. This is often the first indication that the outlet isn’t functioning properly.
  • GFCI Won’t Reset If your GFCI outlet does not reset after pressing the RESET button, it can be a clear indicator of an underlying electrical problem. This could be due to issues such as a faulty outlet, damaged wiring, or a persistent ground fault in the circuit. Frequent Need for Resetting – If you find yourself needing to reset the GFCI outlet often, it could be a sign of an underlying issue within your electrical system that needs to be addressed.
  • Constant Tripping – If the GFCI outlet repeatedly trips and shuts off power, it suggests an ongoing issue such as a ground fault, overloaded circuit, or damaged wiring. Continuous tripping not only disrupts your power supply but also poses a potential safety hazard, signaling the need for a professional inspection ASAP. (Some devices may have an LED light that will illuminate when the circuit trips, making it easier for you to identify and troubleshoot when there is a problem on your own.) 
  • Humming or Buzzing Sounds –  Unusual noises like humming or buzzing from the outlet can indicate loose wiring, a faulty outlet, or internal component damage. These sounds should not be ignored, as they can lead to more severe problems, including electrical fires.
  • Physical Damage – Visible damage to the outlet, such as cracks, burn marks, or discoloration, are all clear signs that the GFCI outlet needs to be replaced. 
  • Warm to the Touch – If the outlet feels warm or hot to the touch, it could indicate an overload or internal issue. This can be a serious safety hazard and requires immediate attention.
  • Indicator Light Issues – Many GFCI outlets have an indicator light that shows their status. If this light is off, flashing, or displaying a color that indicates a problem, it’s a sign that the outlet is not functioning correctly.
Signs Your GFCI Outlet Is Not Working

Why Your GFCI Outlet May Not Be Working

Now that we’ve covered the signs to look out for when it comes to a malfunctioning GFCI outlet, let’s take a closer look at the reasons why you may be experiencing these problems.

Tripped Circuit Breaker

A circuit breaker is a safety mechanism that automatically shuts off electricity to a circuit when it detects an overload or short circuit. When a breaker trips, the switch moves to the “off” or middle position in your electrical panel. Common causes include overloading the circuit with too many devices, short circuits, or ground faults.

To restore power, simply locate the tripped breaker and switch it back to the “on” position. If the breaker continues to trip, you should reach out to a professional electrician to diagnose and address the underlying issue.

Blown Fuse

A blown fuse can be another culprit behind a faulty GFCI. When a fuse blows, it interrupts the circuit, cutting off the power supply to the GFCI outlet and rendering it non-functional. This can occur due to too many devices being plugged in, a short circuit, or faulty appliance. If your GFCI outlet has no power and won’t reset, checking the fuse in your electrical panel is a good first step.

Worn Out GFCI

GFCI outlets generally have a lifespan of about 10 years. However, over time, general wear and tear can cause your GFCI outlet to malfunction or stop working entirely. Daily use, environmental factors such as humidity, and regular plugging and unplugging of devices can degrade the internal components of the outlet. Regular maintenance and timely replacement of aging GFCI outlets are essential to ensure your electrical system remains safe and functional.

Improper Installation

If the outlet is not properly installed, it may fail to provide the necessary protection against ground faults, leading to potential electrical hazards. Common installation errors include incorrect connections, reversing the line and load wires, or failing to secure wiring properly. To ensure your GFCI outlets are installed correctly and safely, it’s important to hire a professional electrician you can trust to handle the process accurately.

Why Your GFCI Outlet May Not Be Working

Moisture Intrusion

Moisture intrusion is another common cause of a GFCI outlet not working, particularly in areas prone to dampness such as kitchens, bathrooms, and outdoor spaces (which happens to be the most common areas for GFCI installation). When moisture seeps into the outlet, it can create a ground fault, causing the GFCI to trip continuously as it tries to protect against potential electric shock.

Faulty Appliances

Faulty appliances may also be to blame for a malfunctioning GFCI. Appliances with internal electrical issues can cause the GFCI to trip frequently as it detects these faults and attempts to cut off power to prevent hazards. This constant tripping can make it seem like the GFCI outlet is malfunctioning when the real issue actually lies within the appliance.

Electrical Surges

Electrical surges, which can be caused by lightning strikes, power outages, or large appliances cycling on and off, can overload the outlet’s internal components, potentially leading to frequent tripping or it failing altogether. Repeated exposure to surges can degrade the outlet’s ability to function properly, compromising its safety features. If you suspect that electric surges are affecting your GFCI outlets, call the team at Lex Air for professional surge protection services today.

Loose Connection

If the GFCI’s screw terminals, stab-in connections, ground wires, or hot and neutral wires are not properly secured, it can interrupt the electrical current, leading to intermittent power loss or causing the outlet to fail completely. Bad electrical connections can create an unstable electrical flow, resulting in the outlet not resetting or tripping frequently.

DIY Troubleshooting Steps for GFCI Outlets

DIY Troubleshooting Steps for GFCI Outlets

  1. Check for Power Supply: Ensure that the GFCI outlet is receiving power by checking if a different outlet on the same circuit is working. If none of the other outlets are working, it might be an issue with the circuit breaker or a blown fuse.
  1. Reset the Outlet: Press the RESET button on the GFCI outlet. If the outlet resets and restores power, the issue might have been a temporary trip.
  1. Test the Outlet: Plug a small appliance or a lamp into the GFCI outlet and press the TEST button to test the outlet’s functionality. The device should turn off. Then press the RESET button to restore power. You may also use a receptacle or circuit tester to see if the outlet is working correctly.
  1. Inspect for Physical Damage: Look for any visible signs of damage, such as cracks, burn marks, or discoloration on the outlet. If you see any damage, it may be time to replace the outlet.
  1. Check for Loose Connections: Turn off the power to the outlet at the circuit breaker. Remove the outlet cover and check for any loose or disconnected screws or wires, including the ground wire, hot wire, and neutral wire. If there are loose connections, go ahead and tighten them securely.
  1. Test Other Outlets: Check if nearby outlets on the same circuit are working. If multiple outlets are not working, the issue might be with the circuit breaker or a wiring problem.
  1. Inspect Main Panel: Locate your home’s electrical panel and check if any circuit breakers have tripped. If you find a tripped breaker, reset it by flipping it to the “off” position and then switch it back to the “on” position.
  1. Check for Moisture: Inspect the GFCI outlet for any signs of moisture or water intrusion, especially in areas prone to dampness. Moisture can cause the outlet to trip frequently.
  1. Disconnect Faulty Appliances: Unplug all devices connected to the GFCI outlet. Reset the outlet and then plug in each device one at a time to identify if a specific appliance is causing the outlet to trip.
  1. Test for Ground Fault: Use a ground fault tester to check if the GFCI outlet is properly detecting ground faults. Follow the instructions provided with the tester for accurate results.

If these steps do not fix the issue, it may be time to contact an experienced Carrollton electrician from Lex for a thorough electrical inspection and repair.
