Generator Repair & Service

Generator repair and service in Auburn and across the Placer, El Dorado and Nevada County foothills, for home standby generators of any brand — Generac, Kohler, Briggs & Stratton, Champion, Cummins and more. As an authorized Generac dealer and a licensed, insured electrical contractor, we handle both sides of the machine: engine service and diagnostics, and the transfer switch, wiring and panel faults that cause a running generator to leave your house dark. Will not start, will not transfer, throwing alarm codes, or just overdue for maintenance — we fix it.

Generator Repair & Service in Auburn — Any Brand

A standby generator that will not start during an outage is worse than not having one, because you planned around it. King Electric & Solar repairs and services home standby generators of any brand throughout Auburn, Placer County, El Dorado County and the Nevada County foothills — Generac, Kohler, Briggs & Stratton, Champion, Cummins and others. We are an authorized Generac dealer, so Generac warranty work and genuine parts come straight from us, and we are a licensed, insured California electrical contractor, which matters because a large share of generator failures are not engine problems at all — they are transfer switch, wiring or panel problems that a small-engine shop cannot legally touch. Whether we installed it or not, we will diagnose it, tell you plainly what it needs, and fix it.

Why Standby Generators Fail — and What We Repair

After enough service calls the pattern is clear. Most no-start failures trace to a handful of causes, and nearly all of them are preventable with attention:

  • The battery — by far the most common failure. A standby generator lives outside and cranks a few seconds a week. Batteries die quietly and the unit looks perfectly fine until the day it has to start. This is the single biggest reason generators fail during an outage.
  • Fuel and carburetion — propane regulator problems, undersized or partly blocked gas lines, stale fuel in units that sat, and carburetors that gummed up between runs.
  • Oil, filters, plugs and valves — overdue service, low or degraded oil, fouled spark plugs and valves out of adjustment, which show up as hard starting, rough running, or a unit that starts and then quits under load.
  • Controller and sensor faults — alarm and error codes, failed sensors, boards that lost their programming, and units stuck in an alarm state that will not clear.
  • Rodent and weather damage — genuinely common out here. Chewed wiring harnesses, nests built against the engine, corroded connections and water intrusion through failed seals.

Transfer Switch & Electrical Faults

When the engine runs fine but the house stays dark, the fault is electrical — and this is where being a licensed electrical contractor rather than an engine shop actually matters:

  • The transfer switch will not transfer — failed contactors, burnt or pitted contacts, failed control boards, and switches stuck in the utility position while a perfectly healthy generator idles outside.
  • Utility sensing problems — the switch never sees the outage, so the generator never gets the start signal, or it starts and immediately shuts back down.
  • Panel and breaker faults — tripped or failed breakers, loose lugs and overloaded circuits on the generator side. See circuit breaker repair and electrical panel upgrades.
  • Wiring, grounding and bonding — incorrect neutral bonding, corroded or undersized conductors and grounding faults, several of which are safety problems in their own right. See electrical troubleshooting.

Annual Maintenance — Book It Before Fire Season, Not During

Nearly every emergency generator call we take was avoidable. A standby unit needs a real service visit on a schedule, and the right time to do it out here is before fire weather and PSPS season, not after the first shutoff when everyone calls at once. A maintenance visit covers the oil and filter change, spark plugs, air filter, valve inspection, a genuine battery test rather than a glance, fuel system and line pressure check, a look at wiring and connections for rodent damage and corrosion, verification that the weekly exercise cycle is actually running, and a load test that proves the unit will carry your house — which is the part a weekly self-test does not prove. On Generac units we also confirm the warranty registration is intact and that Mobile Link monitoring is reporting, so faults reach you rather than sitting unnoticed on the controller.

Repair or Replace? We Will Give You the Honest Answer

Sometimes the right advice is to stop spending money on a machine. We would rather tell you that than sell you a fourth repair on a unit that is finished. Repair usually makes sense when the generator is sound and reasonably aged, parts are still available, and the failure is a battery, a service item, a controller or a transfer switch component — those are ordinary fixes and the unit has plenty of life left. Replacement usually makes more sense when the unit is well past its expected service life, parts are discontinued, it has failed repeatedly across different systems, the engine itself is worn, or it was undersized for the house from the beginning and never really did the job. If replacement is the honest answer we will quote it as an authorized Generac dealer — see Generac generator installation or our general backup generator installation overview — and if repair is the honest answer, we will just fix it.

Frequently Asked Questions

  • Will you service a generator you did not install? Yes — that is a large part of what we do. Any brand, any installer, including units whose original installer is no longer in business.
  • My generator will not start. What is it usually? Most often the battery. After that: fuel supply and regulator problems, overdue service, or a controller fault. We diagnose it rather than swapping parts and hoping.
  • The generator runs but the house has no power. That is almost always the automatic transfer switch or the electrical side rather than the engine — a failed contactor, a control board, or a utility-sensing fault. As a licensed electrical contractor we can actually repair that, not just report it.
  • How often does a standby generator need service? Annually as a baseline, and ideally scheduled ahead of fire season. Heavy use during a long outage season warrants a visit afterward too.
  • Do you do Generac warranty work? Yes — we are an authorized Generac dealer, so warranty service and genuine Generac parts come directly from us.
  • Can you service Kohler, Briggs & Stratton, Champion or Cummins units? Yes. We repair and maintain home standby generators of any brand.
  • My unit runs its weekly test fine — does that mean it is ready? Not necessarily. A self-test proves it starts; it does not prove it will carry your house under real load. That is what a load test during a service visit is for.
  • Is my generator worth repairing? We will tell you straight. Age, parts availability, repeat failures across different systems and whether it was correctly sized in the first place all factor in — and if replacing it is the better value, we will say so.
