Diagnose Fast, Fix Right
Electrical Troubleshooting & Repair
Dead outlets, tripping breakers, flickering lights, burning smell — we diagnose the root cause with real test gear and fix it right the first time.

If you're experiencing any of these, don't keep resetting the breaker — call us. Most get worse and more expensive the longer you wait.
Dead Outlets
No power at an outlet? Could be a tripped GFCI upstream, loose backstab, or open neutral. We trace the circuit and fix the source.
Tripping Breakers
Overloaded circuit? Short? Ground fault? Failed breaker? We isolate the root cause with clamp-on amp readings and continuity testing.
Flickering Lights
Loose neutral, failing dimmer, voltage drop, or utility issue? We test under load to pinpoint the cause — not just swap the bulb.
Buzzing or Humming
Buzzing from panel or outlet means arcing — fire risk. We open it up, find the loose lug or backstab, and tighten/replace per torque spec.
Hot Outlets or Switches
Warm covers = overloaded wiring or bad connection. Immediate hazard. We thermal-image, identify the failing junction, replace with proper-rated parts.
Burning Smell
Electrical burning smell is an emergency. Turn off the affected circuit at the breaker and call us. We dispatch same-day, often within hours.
Partial Power Loss
Half the house dark? Usually a failed leg in the main breaker, loose connection at the meter, or PG&E side issue. We diagnose and coordinate with PG&E if needed.
Outdated Wiring
Aluminum branch circuits, knob-and-tube, cloth-insulated wire — all documented fire hazards. We replace with modern copper to NEC standards.
Call to Repair
One phone call to a fully repaired circuit, usually the same day.
Phone Triage
Call (650) 550-0719 — we triage on the phone: is this an emergency? Can you reset something safely? Same-day dispatch confirmed.
On-Site Diagnostic
Licensed electrician arrives with full test gear — multimeter, clamp meter, thermal imager, outlet tester. Diagnosed properly, not guessed.
Fixed-Price Fix
Root cause identified. Written fixed-price quote for the repair before any work starts. Most fixes done same-visit.
Tested + Documented
Repair tested under load, all readings within spec, you get a written report (what failed, what was replaced, warranty).
Why Fox for Troubleshooting
Diagnose, Don't Guess
Full test gear — multimeter, clamp meter, thermal imager. We measure under load and find the actual root cause, not swap parts hoping.
Same-Day Emergency
Active hazard? Sparking, burning smell, no power, smoke? Dispatched within 1-2 hours, evenings and weekends included.
Parts in the Truck
Breakers, outlets, switches, GFCI/AFCI, common wire gauges — most repairs finished same visit, not "we'll come back tomorrow with parts."
Written Diagnostic Report
You get a written report — what failed, what was replaced, all readings, warranty terms. Important for insurance claims and resale disclosure.
Federal Pacific / Zinsco
These panels regularly fail to trip — that's what we find on a lot of troubleshooting calls. We diagnose and recommend replacement if warranted.
12-Month Warranty
If the same issue recurs and traces back to our repair, we come back free. Workmanship warrantied for a full year.
Troubleshooting Questions
How fast can you come out for an electrical problem?
For active hazards (sparking, burning smell, smoke) — within 1-2 hours, including evenings and weekends. For non-emergencies (dead outlet, tripping breaker) — usually same-day or next-day depending on schedule. Call (650) 550-0719 for current availability.
What does troubleshooting cost?
We diagnose the problem, explain what we found, and quote the repair on the spot — call our team for current diagnostic pricing. If you proceed with the fix, we get started right away.
Can you fix the problem the same day you diagnose it?
Most issues yes — we carry standard parts (breakers, outlets, switches, GFCI/AFCI devices, common wire gauges) in the truck. Larger repairs (panel replacements, rewiring) get scheduled but quoted on the spot.
Do you handle PG&E side issues?
If we determine the problem is on PG&E's side of the meter, we document it and help you file the PG&E claim. We can't work on the utility side ourselves, but we know how to escalate.
My breaker keeps tripping. Should I just replace it?
Almost never. Breakers trip because something is wrong with the circuit — overload, ground fault, short. Replacing the breaker without finding the cause means the new one will trip too, or worse, fail unsafely. We trace the actual issue.
I have aluminum wiring — is that a problem?
Aluminum branch circuits (1965-1973 homes) are a documented fire risk due to oxidation at connections. We don't always rip out all the aluminum, but we install AlumiConn or COPALUM connectors at every junction to mitigate. Some insurers require this.
Can you work on knob-and-tube wiring?
Yes. We assess what's active vs decommissioned, recommend full replacement in occupied areas, and document for insurance. Most home insurance now refuses to renew on active K&T.
What's your warranty on troubleshooting work?
Workmanship warrantied for 12 months. If the same issue recurs and is traceable to our repair, we come back and fix it free.
Why does my breaker keep tripping even after I reset it?
A breaker that trips repeatedly is doing its job and warning you of an overloaded circuit, a short, or a ground fault. If it trips again within seconds of resetting, stop resetting it and call a licensed electrician, because the cause can be a damaged wire or a failing breaker that becomes a fire risk.
My breaker won't reset. Is that an emergency?
A breaker that will not move back to "on," or that snaps off immediately, usually means there is an active fault on that circuit. Leave it off and call us; forcing it can damage the panel, and a dead circuit often points to a problem that needs to be found before it spreads.
Why does my AFCI / arc-fault breaker keep tripping for no reason?
Arc-fault breakers are required in living areas and trip on the tiny dangerous arcs a normal breaker ignores, so "no reason" is often a real loose connection, a damaged cord, or an incompatible appliance. We test the circuit to tell a true hazard from a nuisance trip and fix the source rather than just swapping the breaker.
Half my outlets stopped working but the breaker isn't tripped. Why?
This often comes from a tripped GFCI upstream, a loose "backstabbed" connection in one outlet, or a failing neutral feeding the rest. Because the cause is hidden, it is worth having it traced; a loose neutral in particular can damage appliances and start a fire.
Why do my lights flicker or dim when the AC or an appliance turns on?
A brief dim when a big motor starts can be normal, but persistent flicker across the house often means a loose connection, an undersized service, or a failing panel lug, which can be dangerous. If it is widespread or getting worse, have it checked promptly.
Are flickering lights throughout the house dangerous?
Whole-house flickering, as opposed to one bad bulb, can signal a loose neutral or a connection problem at the panel or meter, which is a real fire and equipment risk. It is worth a same-day look rather than waiting.
Is the buzzing or humming sound from my electrical panel normal?
A faint hum can be normal, but loud buzzing, crackling, or a hot panel cover means a loose connection or failing breaker and should be treated as urgent. Do not open the panel yourself; call a licensed electrician.
