Szeto HandymanWhat a GFCI does
- Tenants can open up
- A code for the GFCI outlet visit
A ground-fault circuit interrupter outlet watches the current going out on one wire and coming back on the other. If they do not match, some current is leaking somewhere, possibly through a person. The GFCI cuts power in a fraction of a second. That is why they are in bathrooms, kitchens, laundry rooms, garages and outdoors, where water and electricity meet.

Dead outlets with no tripped GFCI in sight
One GFCI can protect several regular outlets downstream on the same circuit. The GFCI that controls a dead bathroom outlet might be in another bathroom, in the garage, or outside by the back door. Walk the house and press reset on every GFCI you find.
Check the breaker panel for a tripped breaker too. Many dead-outlet calls end right here.
Safe checks
- Unplug everything from the GFCI and the outlets it protects.
- Press reset firmly. If it clicks and stays, plug items back in one at a time to find the one that trips it.
- If it will not reset, check the breaker for that circuit and reset it.
- Try reset again.
Never open the outlet box or remove the device while the circuit is on. If you are unsure, stop and text us.
Why a GFCI keeps tripping
- A faulty appliance: hair dryers, old power tools and holiday lights with damaged cords are common.
- Moisture: outdoor outlets without a proper in-use cover, or connections lying in wet grass, trip after rain or sprinklers.
- A worn GFCI: devices age. One that trips with nothing plugged in, or will not reset, may simply be at the end of its life.
- Wiring problems: damaged wire in a wall, or a wiring fault downstream.
When a device swap fixes it
If the circuit is healthy and the GFCI itself has failed, replacing it with a new GFCI in the same box is like-for-like work that we do. We test the circuit, install the new device with the line and load wires correctly, and check that the downstream outlets are protected. See outlet, switch and GFCI replacement.
Electrical work outside our scope
Burning smells, scorch marks, warm outlets, buzzing, a breaker that trips again immediately, or a GFCI that trips even with everything unplugged after a new device is installed all point to a wiring problem. Those are outside our scope. We say so clearly rather than guessing.
Monthly test
- Free price by text
- No surprises on the GFCI outlet
Press the test button on each GFCI once a month. Power should cut. Press reset and it should return.
A GFCI that will not trip on test is not protecting you and should be replaced. For outdoor use around the holidays, see holiday light hanging.
Line and load
A GFCI has two sets of terminals: line, which brings power in, and load, which feeds the outlets downstream. If they are swapped during an install, the GFCI may not reset or may leave downstream outlets unprotected. Many new GFCIs will not reset at all if wired backward, which is a safety feature. This is one reason we test the whole circuit after installing one.
- RESET will not stay in after the load is unplugged
- It trips with nothing plugged in
- TEST does not cut the power
- The face is cracked, scorched or warm
- The indicator light, on models that have one, shows a fault
- It trips again right after every reset
Old outlets without a ground
In older homes with two-prong outlets, a GFCI can be installed to add shock protection even without a ground wire, labeled no equipment ground. It will still trip and reset normally.

- Cut the powerFlip it and test that nothing turns on.
- Hands off if scorchedBurn marks or loose wiring are a stop sign.
- Send picturesA shot of the GFCI outlet and the panel helps.
Refrigerators and freezers
If the fridge or a garage freezer is on a GFCI that trips, food can spoil without anyone noticing. Check garage and kitchen GFCIs after power outages and before trips.
Combination devices
Some homes have GFCI breakers in the panel instead of GFCI outlets. They have their own test button on the breaker. If outlets are dead and you cannot find a GFCI outlet, look for one in the panel.
Testing the outlets downstream
A plug-in tester with a GFCI button lets you trip the GFCI from each downstream outlet. If pressing it at a downstream outlet does not trip the GFCI, that outlet is not protected and needs a closer look.
After a storm
Rain and sprinklers soak outdoor outlets. Let a wet box dry, then reset. If it trips again once dry, the device or cover needs replacing.
- TEST button: cuts power to check it works
- RESET button: restores power
- Outlets further down the line share its protection
Bathroom fans and lights
In some homes, the bathroom light or fan shares the GFCI circuit. If the light goes out with the outlet, the GFCI is the place to start. Moisture from showers can also trip a worn GFCI. A working bath fan helps keep the bathroom dry and the GFCI calm; see our bath fan page.
What we bring
We carry standard and tamper-resistant GFCIs in white, light almond and black, plus weather-resistant GFCIs and in-use covers for outdoor boxes. Every swap ends with a test of each outlet the GFCI protects.
- Fixtures on existing boxes
- Switches and outlets swapped
- GFCI outlets replaced
- Fans on rated boxes
- New circuits or outlets
- Panel and breaker work
- Rewiring or moving boxes
- Anything scorched or arcing

Questions we get
Why are my bathroom outlets dead?
A GFCI elsewhere may have tripped. Reset every GFCI in the house.
Can I replace a GFCI myself?
If you are not comfortable working with electricity, have it done.
Why does my outdoor GFCI trip when it rains?
Moisture in the box or a connection. A proper in-use cover helps.
- GFCI outlet parts named up front
- Bring your own
Do you replace GFCI outlets?
Yes, like-for-like in existing boxes on healthy circuits.
Which electrical work is outside your scope?
Burning smells, warm outlets, or repeated trips with nothing plugged in.
How do I find the GFCI that controls a dead outlet?
Check the kitchen, bathrooms, garage, laundry and outdoor outlets. One GFCI can protect several outlets downstream.
- Text (310) 628-9399
- Phone about the GFCI outlet in open hours
Does a GFCI wear out?
Yes. Pressing TEST monthly shows whether it still trips; if it does not, replace it.
Why does it trip when I use a hair dryer?
It may be overloaded, or the appliance may have a fault. Try another appliance to compare.
Is it safe to keep resetting it?
If it trips again and again, stop and have the circuit checked.

Good to fix along with the GFCI outlet
Easy to add on the same trip: GFCI and switch replacement or electrical fixture repairs. If the cause is elsewhere, see holiday light hanging; porch light and floodlight swaps and Urgent home repairs: what to do first come up often too.
