Stay Prepared
Common Standby Generator Problems We Repair
As part of standby generator repair in Larkspur, CA, our certified technicians resolve a broad array of component failures. Below are the primary issues we address during generator troubleshooting in Larkspur homes.
- Start-up Failure & Ignition Issues — no-start conditions caused by depleted batteries, gummed-up carburetors, defective fuel solenoids, or malfunctioning transfer switches
- Generac Diagnostic Fault Codes — we accurately interpret and repair Code 1300 (low oil pressure), Code 1400 (overcrank), and Code 1505/1515 (fuel or internal system faults)
- Battery Degradation — units that show sufficient charge may idle but collapse under actual starting loads; routine replacement of batteries every 3 to 4 years prevents unexpected outages
- Fuel Supply System Blockages — fuel breakdown and varnish buildup during long idle periods that obstruct carburetors and fuel lines, a leading cause identified in standby generator troubleshooting
- Oil Pressure & Leak Repair — active leaks at the valve cover, oil pan, or filter housing that risk critical engine damage from low oil levels
- Cooling System Failure & Overheating — worn hoses and gaskets causing coolant leaks that result in overheating or complete engine shutdown
- Automatic Transfer Switch Failures — situations where the generator runs properly but fails to transfer power to the electrical panel; requires evaluation by a licensed electrician
- Electrical & Wiring Corrosion — moisture-induced terminal and wiring degradation common in properties near Baltimore Canyon and hillside locations around Madrone Canyon
