How to Troubleshoot a Tripped GFCI and a Tripped Circuit Breaker
When an outlet or a section of your home loses power, it can be frustrating. However, the cause is often a tripped Ground Fault Circuit Interrupter (GFCI) outlet or a tripped circuit breaker in your electrical panel. Knowing how to troubleshoot these issues can save you time and money.
Troubleshooting a Tripped GFCI Outlet
GFCI outlets are designed to prevent electrical shocks by shutting off power when they detect a ground fault. They are commonly found in kitchens, bathrooms, garages, and outdoor areas.
Step-by-Step Guide:
1. Identify the Tripped GFCI Outlet
- Look for GFCI outlets in the area where power was lost.
- A tripped GFCI will have its "RESET" button popped out.
2. Reset the GFCI
- Press the "RESET" button firmly until it clicks.
- If the GFCI holds, your power should be restored.
3. Check for Additional GFCIs
- Some homes have multiple GFCIs on the same circuit.
- Locate and reset all GFCI outlets in your home.
4. Test the GFCI Outlet
- Plug in a small appliance (like a lamp or phone charger) to ensure power is restored.
5. If the GFCI Won’t Reset
- Unplug all devices on the same circuit, then try resetting.
- Check for moisture or debris inside the outlet (especially outdoors).
- If the outlet still won't reset, the GFCI may be faulty or there may be a wiring issue, requiring professional help.
Troubleshooting a Tripped Circuit Breaker
Circuit breakers trip when they detect an overload, short circuit, or ground fault to prevent electrical fires and damage.
Step-by-Step Guide:
1. Locate the Electrical Panel
- Typically found in basements, garages, utility rooms, or outside.
- Look for a breaker switch that is in the "OFF" position or halfway between "ON" and "OFF."
2. Reset the Circuit Breaker
- Turn the breaker completely OFF, then flip it back to ON.
- You should hear a click when it resets.
3. Identify the Cause of the Trip
- Overloaded Circuit: Too many devices on one circuit (e.g., running a microwave and toaster on the same outlet).
- Short Circuit: A faulty appliance or damaged wiring.
- Ground Fault: A moisture-related issue or faulty wiring.
4. Check for Recurring Trips
- If the breaker trips immediately after resetting, unplug all devices and try again.
- If it still trips, call a licensed electrician to inspect for wiring issues.
When to Call a Professional
- If a GFCI won’t reset despite all troubleshooting steps.
- If a breaker keeps tripping after unplugging devices.
- If there’s a burning smell near an outlet or panel.
- If you see sparks or signs of electrical damage.
