Why Your GFCI Outlet Keeps Tripping – And When to Call an Electrician

Is your GFCI outlet not working? Experiencing frequent tripping? You’re not alone. This issue is more common than you might think, and it’s actually your home’s way of protecting you.

GFCI (Ground Fault Circuit Interrupter) outlets are safety devices that cut power when they sense electricity going somewhere it shouldn’t—like into water, a person, or the wrong part of a circuit. When they trip, they’re doing their job. But if they trip constantly, it may point to a bigger problem.

Here’s a list of common causes, what to look out for, how to fix it, and who to call for help.

Common Causes of a GFCI Outlet Not Working

1. Moisture Got In
   Bathrooms, kitchens, basements, and outdoor spaces are where GFCIs are most common, and they’re also where moisture sneaks in. If water gets inside the outlet or the box behind it, the GFCI will trip to protect you.
2. Too Many Things Plugged In
   If you’re using multiple appliances on the same outlet or circuit, like a refrigerator and microwave, the GFCI may trip because it’s overloaded.
3. One of Your Appliances Has a Problem
   A slightly damaged cord, internal short, or even a small current leak in a plugged-in device can cause a GFCI to trip. This is often the case when everything seems fine, but the outlet keeps popping off.
4. The Wiring Isn’t Right
   Loose wires, old connections, or improper GFCI outlet wiring can make your outlet trip unexpectedly or stop working altogether. If your outlet was installed many years ago or DIY style, this might be the issue.
5. A Surge or Lightning Strike
   Power surges from nearby lightning or fluctuations from the power company can also cause a GFCI to trip as a precaution. If you notice this after a storm or brownout, that could be the cause.

How to Identify GFCI Outlet Issues

1. Moisture Exposure
   Install weather-resistant covers and ensure outdoor and bathroom outlets are sealed properly.
2. Balance the Load
   Avoid plugging too many high-power appliances into a single GFCI-protected circuit.
3. Appliance Troubleshooting
   Use a multimeter to test appliances or consult a professional if you're unsure.
4. Routine Maintenance
   Test your GFCI outlets monthly using the "Test" and "Reset" buttons to ensure they function properly.
5. Electrical Inspections
   Have your electrical system inspected annually, especially in older homes or before purchasing a new property.

How to Prevent GFCI Outlet Problems

1. Keep It Dry
   Make sure outlets near water sources are sealed well and use covers outdoors.
2. Don’t Overload
   Contact a professional to add additional outlets or circuits to the area so you can spread out the load of high-energy appliances.
3. Check Your Devices
   If an outlet trips when something is plugged in, unplug it and try a different device. That might help you narrow it down.
4. Test It Monthly
   Press the “Test” button, then the “Reset” button on the outlet. If it doesn’t reset, it may need replacement.
5. Get a Checkup
   Especially in older homes, regular electrical inspections can catch wiring or outlet issues early.

When to Replace GFCI Outlets

If your GFCI outlet is not working properly despite resetting, it might be time to replace it. Signs that you need to replace GFCI outlets include:

• The outlet won't reset.

• It trips immediately after resetting.

• Visible damage or wear.

• The test button doesn't function.

• It’s been over 10 years since it was installed.

Why Professional Installation Matters
