Electrical Repairs for Outlets, Switches, Lights and Breakers
Most repair calls start with one thing that stopped working: an outlet, a light, a switch, a breaker that won’t hold. We find out why before we replace anything, because a dead outlet can be a worn device, a loose wire two outlets away or a circuit carrying more than it should.
Common Repairs
These are the problems we see most in houses, apartments and small shops around San Gabriel. The table shows what each one usually looks like and what to do next.
| Problem | What you may notice | Usual cause | Next step |
|---|---|---|---|
| Dead outlet | Nothing works when plugged in, other outlets fine | Tripped GFCI upstream, loose backstab connection, worn receptacle | Reset GFCIs and the breaker; call if still dead |
| Flickering lights | One fixture flickers, or several dim together | Loose bulb or socket, a failing dimmer, a loose neutral | Try a new bulb; if several flicker, call soon |
| Breaker that trips | The same circuit goes off, often with the same appliance | Too much on one circuit, a damaged cord, a short | Unplug, reset once; call if it trips again |
| Warm outlet or switch | Plate warm to the touch, faint smell, discoloring | Loose connection heating up, an overloaded device | Stop using it and call now |
| GFCI won’t reset | Reset button won’t latch, or trips right away | Ground fault downstream, water in an outdoor box, a worn GFCI | Unplug everything on it and retry; then call |
| Part of the house dark | Several rooms out, no breaker tripped | A loose connection at the panel or the meter, a failed breaker | Call; don’t open the panel yourself |
Stop and Call Now
Turn off the circuit at the panel if you can do it safely, stop using the outlet or fixture and call us if you notice any of these:
- A burning smell, or the smell of hot plastic, near an outlet, switch or the panel.
- An outlet or switch plate that’s warm or hot to the touch.
- Sparking when something is plugged in or a switch is flipped.
- A buzzing or crackling panel.
If you see smoke or flames, get everyone out and call 911.
Tracing the Fault Before Replacing Parts
We start with what you noticed and when it happens, then test the circuit from the device back toward the panel. Old wiring in older San Gabriel houses gets particular attention: brittle insulation, cloth-covered cable and outlets with no ground are common, and a repair in one box can turn up a problem in the next one. We explain what we find as we go, so you know what was wrong and what we did about it.
Many fixes are simple once the cause is found: a receptacle with a loose backstab connection rewired onto its screws, a worn switch replaced, a dimmer swapped for one rated for the bulbs it controls. Some repairs point to a bigger issue, like a circuit that’s always overloaded. When that happens, we’ll tell you, and you decide what to do next.
If you’d like to narrow things down before you call, our breaker troubleshooting guide walks through the safe checks.
Rey was awesome called him last week because of a faulty switch in my daughters room. He was able to get the part and he even came over on a sunday to do a quick install for us. Super nice guy and I would highly recommend him
Repair Questions
Why would one outlet stop working when the breaker is still on?
Most often a GFCI outlet somewhere upstream has tripped. It could be in a bathroom, the kitchen, the garage or outside, and it cuts power to the outlets wired after it. If resetting every GFCI doesn’t help, the next suspect is a loose connection in that outlet or the one before it.
Are flickering lights dangerous?
One flickering bulb is usually the bulb, its socket or a dimmer that doesn’t match it. Lights in several rooms flickering or dimming together can mean a loose connection on a shared wire, which can heat up. That one is worth a call sooner rather than later.
My GFCI won’t reset. What now?
Unplug everything on that outlet and the ones after it, then press reset firmly. If it still won’t latch or it trips right away, there may be a fault downstream, moisture in an outdoor box, or the GFCI may simply be worn out. We’ll find which one it is.
Do you fix problems in apartments and shops too?
Yes. Landlords call us for repairs in their units, and business owners for shops and offices. The troubleshooting is the same; the buildings and the panels are just laid out a little differently.
