Generator Repair FAQs

Why does my standby generator fail its self-test?
Battery, fuel supply, or a fouled plug covers most of it. A Diamond Bar generator tech will run it under load and find the real fault rather than reset it and hope.
How often should a standby generator be serviced?
Once a year at minimum, plus an oil change after any long run. Diamond Bar techs usually offer an annual plan that keeps it under warranty and ready for the next outage.
