Does this sound familiar?

Generators are complex machines. Don't wait until the next storm to find out yours isn't working.

If your system is exhibiting any of these symptoms, it requires immediate diagnostic attention from a certified technician.

Generator Repair & Troubleshooting FAQs

Verified diagnostic steps, common error code remedies, and emergency dispatch procedures from our master electrical technicians.

A red fault light indicates the generator control board has locked out the engine to prevent catastrophic mechanical or electrical damage. Common triggers include low oil pressure, overcrank (engine attempted 5–7 start cycles without ignition), overspeed / RPM sensor mismatch, low battery voltage (under 12.0V DC), or auxiliary shutdown activation. Do not repeatedly cycle the main breaker. Contact 4BEYOND for 24/7 digital fault code interrogation and emergency technician dispatch.
