PANEL REPAIR
Buzzing, hot, or tripping panel? A licensed electrician opens the cover, runs the diagnostic, and quotes the actual fix in writing.
Keil Electric repairs residential and commercial electrical panels in San Diego County and the Austin metro. We diagnose buzzing, heat, repeated tripping, scorched bus bars, and loose lugs. A licensed electrician opens the panel, runs the diagnostic, and writes a fixed-price quote before any work begins.
Same scope on either side. Pick the shop that covers your area and we will route you to the right crew.
Symptoms drive the diagnostic. We check the bus bars for heat damage and discoloration, inspect each breaker for loose lugs and arc tracking, look for double-tapped neutrals, and confirm the main bonding jumper is intact. Then we test under load to see whether the issue is the panel itself or a downstream circuit.
Loose breaker connections from age and thermal cycling. Heat damage at the bus stabs, especially behind tandem breakers. Scorched neutral bars where a loose connection cooked itself. Failed main breakers that no longer trip cleanly. Federal Pacific Stab-Lok and Zinsco panels that need full replacement, not repair, because the breaker mechanism itself is unsafe.
Repair makes sense when the panel itself is sound and the failure is localized to a breaker, a single bus connection, or a loose lug. We document the repair scope, replace the bad components with manufacturer-spec parts, and re-torque every connection in the panel before closing it up.
If the panel is FPE Stab-Lok, Zinsco, or any of the recalled obsolete designs, repair is unsafe. Same call when the bus bars are scorched, the panel is undersized for current load, or the manufacturer has stopped making compatible breakers. We will say so in writing and quote the replacement.
You describe what you are seeing or smelling. We confirm the urgency level on the call and schedule accordingly.
A licensed electrician arrives, opens the panel, and runs the inspection under power-down where required.
We write the repair scope, parts list, and labor in fixed terms. You sign before any work begins.
We replace the bad components, re-torque every connection, and verify the panel under load before closing the cover.
Not every job requires a permit. When the local AHJ requires one, we pull it, schedule the inspection, and stay with the job until it passes. No paperwork on you.
Written warranty: 5-year on outlets, fixtures, and EV chargers; 10-year on wire and breakers; lifetime on panelboxes and surge protection. Parts and labor. Transfers with the home.
A panel that smells like burning plastic, runs hot to the touch, or makes audible buzzing is a fire risk. Stop using the affected circuits and call us. Do not pull the panel cover yourself if you smell smoke.
Real work from our San Diego and Austin shops. Same standards, same warranty, every job.
For electrical panel repair, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.
Most electrical panel repair calls fall into one of three patterns: a single component failed and the symptom is obvious, a slowly degrading connection finally tripped or stopped working, or a previous repair (yours, a handyman, or a prior contractor) was never quite correct and the underlying issue surfaced again. If the symptom involves smoke, sparks, burning smell, or a panel that is hot to the touch, do not wait. Call the local shop. Active hazards get same-day dispatch when capacity allows. Routine repairs go on the next-available slot, usually inside the same week.
The first 20 to 30 minutes is observation and diagnosis: walk the symptom with you, check the panel for related issues, trace the affected circuit, identify the actual root cause rather than the easy answer. Most electrical panel repair issues sit somewhere other than where the symptom shows up (lights flicker because of a loose connection at the panel, an outlet stops working because of a backstab failure on the next outlet downstream). The diagnostic is the actual job, the price reflects that. We write the scope after the diagnosis, not before.
An electrical panel is the safety hub of your house or building. When it fails, every circuit downstream is affected. We get panel repair calls weekly across both shops, and the symptoms cluster into a handful of categories: buzzing, heat, repeated breaker trips, partial power loss, and visible damage. Each one tells us something different about what is happening inside the panel.
A buzz at the panel almost always means a loose connection somewhere. Heat means resistance, which means a connection that is no longer tight enough to carry the current cleanly. Breakers that trip immediately under no load are usually failed breakers, not overloaded circuits. Breakers that trip under specific loads tell us the circuit itself or the connected equipment is the problem, not the panel.
Federal Pacific Stab-Lok and Zinsco panels are well-documented failures. The breakers do not trip reliably, which means a fault in the house can run the wire hot until something melts. We do not repair these. We replace them. Square D, Eaton, GE, and Siemens panels are usually repairable when a single component fails, with manufacturer-spec replacement parts.
We pull the dead-front cover. We inspect every breaker for arc tracking and lug heat damage. We check bus bar condition. We confirm the main bonding jumper, the grounding electrode connection, and the neutral bar are correct. We test the main breaker. We measure current under load on the bigger circuits. Then we tell you what we found and what it costs to fix.
A panel that buzzes audibly is failing. The buzz is usually a loose connection arcing inside the panel. That can scorch bus bars, melt insulation, or start a fire. Stop using the panel and call a licensed electrician.
It depends. Loose lugs, single bad breakers, and minor heat damage are repairable. Scorched bus bars, FPE Stab-Lok or Zinsco panels, undersized service, or panels with unavailable parts need full replacement. We tell you which path applies in writing.
It depends on what failed. A single bad breaker is a smaller repair. Bus bar damage or main breaker replacement runs higher. We quote in writing after a diagnostic visit so you know the number before any work happens.
Permit requirements vary by city and by scope. Component-level repairs typically do not require a permit. Anything that touches the service entrance or main breaker usually does. We confirm the permit path on the call and include it in the quote when applicable.
Most localized panel repairs are completed in two to four hours, including the diagnostic and re-test. Complex repairs that involve utility coordination or service-entrance work can run a day. We give you a real time estimate before starting.
Tell us what is happening at the panel and a licensed electrician schedules a diagnostic visit. The quote you sign is the bill you pay, backed by our written warranty.
