A GFCI outlet that won’t reset is protecting you from something — the question is what. Ground-fault circuit interrupters are designed to trip in milliseconds when they detect current leaking to ground, and if the reset button will not stay in, there is a reason. Here is how to work through it safely.
1. No power to the outlet. The upstream breaker is tripped, or the outlet is fed from another GFCI that itself has tripped. 2. A ground fault is still present. Something plugged into the circuit is leaking current to ground. 3. Moisture inside the outlet from rain, humidity, or a spill. 4. Line and load wires reversed during installation. 5. The GFCI itself has failed. These devices have a useful life of about 10 to 25 years and eventually wear out internally.
Work through these steps in order. Most homeowners fix the problem before step 4.
Step 1: Unplug everything on that circuit — including anything on connected outlets downstream. Step 2: Check your breaker panel for a tripped breaker and reset it. Step 3: Look for other GFCI outlets in the house (bathrooms, garage, kitchen, exterior) and press reset on each one — they may be daisy-chained. Step 4: If the outlet has been wet, cut power at the breaker and let it dry for 24 hours before testing again. Step 5: With everything unplugged and the breaker on, press RESET firmly. If it still will not hold, the GFCI itself is likely faulty.
The Electrical Safety Foundation International recommends testing every GFCI in your home monthly by pressing the TEST button. If pressing TEST does not produce an audible click and cut power, the internal mechanism has failed — the outlet is no longer protecting you and needs to be replaced. Silent test button equals dead GFCI, every time.
The part costs $20–$40, but it must be wired correctly. GFCI outlets have LINE terminals (power in) and LOAD terminals (power out to downstream outlets). Reversing them makes the outlet appear to work but disables the protection entirely — a common and dangerous DIY mistake. In Ontario, non-owner electrical work also requires an ESA permit and inspection.
If you are not comfortable identifying line vs. load, a licensed electrician can swap a GFCI in about 20 minutes. Browse our outlet and switch services for local options.
Nine times out of ten, a GFCI that will not reset in a bathroom or kitchen is doing its job — there really is a ground fault somewhere on the circuit, usually a small appliance with a failing internal component (a hair dryer with a bad heating element, a coffee maker with a cracked plug). Unplug everything, reset the GFCI, then plug items back in one at a time. Whichever one trips it again is your culprit — and it belongs in the trash, not another outlet.
Continuous ground fault on the circuit, wired incorrectly (line/load reversed), or the GFCI has failed.
Unplug everything from the circuit and try to reset. If it still will not, the GFCI is likely bad.
Press the TEST button. It should trip. If it does not, the GFCI is dead.
Typically 10–15 year lifespan. Test monthly.
Yes for like-for-like on a primary residence. Kill the breaker first.
