Onan EC-AGS+ unexpected generator start or stop
The EC-AGS+ troubleshooting tables tie unexpected starts or stops to temperature settings, quiet-time settings, mobile-device clock settings, house-battery start/stop voltages, start/stop times, and accelerometer-fault alerts.
Owner-safe checklist
- If the generator starts unexpectedly in an unsafe location, use the local or remote physical stop control and disable AGS from the app.
- Record temperature setting, quiet-time window, mobile-device clock/time zone, house-battery start and stop settings, and active alerts.
- Do not use AGS as life support power; the manual warns the generator set/control can stop without warning.
- Use qualified service for repeated unexpected starts or stops, accelerometer faults, generator faults, gateway diagnosis, or control diagnosis.
