GFCI Outlet Keeps Tripping: Causes & How to Fix It
A GFCI outlet trips when it detects a ground fault or moisture, which is actually a safety feature protecting you from electrical shock. Most trips are caused by moisture, damaged appliances, or overloaded circuits and can be fixed by resetting the outlet or identifying the problematic device. Parts are inexpensive (under $20), and the fix typically takes just minutes.
Step-by-Step Fix
- 1
Locate and press the reset button
Find the small black or red reset button in the center of the GFCI outlet. Press it firmly until you hear a click. If the outlet powers back on, the reset was successful and you're done. If it trips again immediately, proceed to the next step.
- 2
Unplug all devices connected to the outlet
Disconnect every appliance, charger, or device plugged into the GFCI outlet. Press the reset button again. If the outlet stays on with nothing plugged in, one of your devices is causing the trip.
- 3
Plug devices back in one at a time
Reconnect each device individually and wait 30 seconds to see if the outlet trips. Continue until the outlet trips again. The last device you plugged in is likely damaged and causing the ground fault.

Test the problematic device on another outlet
Plug the suspect device into a standard (non-GFCI) outlet to confirm it's the culprit. If it trips that outlet too, the device is faulty and should be replaced or repaired. If nothing trips, the device may just be sensitive to moisture.
- 5
Check for moisture or water exposure
Inspect the outlet and surrounding area for water, condensation, or dampness, especially if the outlet is in a bathroom or kitchen. Dry the area completely with a cloth. If moisture is present, do not use the outlet until it dries fully or consider installing a waterproof outlet cover.

Replace the outlet if problems persist
If the outlet trips with nothing plugged in or after drying, the GFCI outlet itself may be faulty and need replacement. Turn off power at the breaker, unscrew the outlet, and install a new GFCI outlet (they cost $15-25). If you're unsure, call an electrician.
⚠️ Safety Notes
- Do not ignore repeated GFCI trips, as they indicate a genuine electrical hazard; never bypass or disable the outlet.
- Always turn off power at the circuit breaker before replacing a GFCI outlet to avoid electrical shock.
- Do not use the outlet if it remains wet or shows signs of water damage; call an electrician to assess the wiring.
When to Call a Pro
Call an electrician if the GFCI outlet trips repeatedly with nothing plugged in, if multiple outlets in your home are tripping, or if you notice burn marks, a burning smell, or charred plastic around the outlet—these signs indicate a wiring fault or internal damage that requires professional repair.
Frequently Asked Questions
- Why does my GFCI outlet keep tripping?
- GFCI outlets trip to protect you from electrical shock when they detect a ground fault or moisture. Common causes are wet hands, bathroom humidity, a faulty appliance, or a damaged outlet itself.
- How do I reset a GFCI outlet?
- Press the small black or red reset button in the center of the outlet firmly until it clicks. If it trips again immediately, unplug everything and press reset—if it stays on, one of your devices is causing the problem.
- Can I use a GFCI outlet if it keeps tripping?
- No, do not continue using the outlet if it keeps tripping; this is a safety mechanism alerting you to a real electrical hazard. Find and fix the cause before regular use.
- How much does a GFCI outlet cost to replace?
- A new GFCI outlet costs $15-30 at any hardware store and takes about 10 minutes to install yourself if you turn off the breaker first.
- Is a tripping GFCI outlet dangerous?
- The outlet itself is not dangerous—it is working correctly by stopping power to prevent electrical shock. However, the reason it tripped (moisture, faulty device, or damaged wiring) could be dangerous if ignored.
