What 36 means
The Cummins Onan Quiet Diesel 5000 HDKBA operator manual lists Code 36 as Engine Stopped.
Owner-safe checks
- Stop the generator.
- Check fuel level and obvious exterior airflow blockage only if safe.
- Record load, run time, weather, and whether the generator restarted.
Service-only work
- Electrical output, inverter, controller, stator, rotor, fuel injection, sensors, wiring, coolant-system service, fuel leaks, and generator compartment repairs belong to Cummins service or a qualified generator technician.
Safety boundary
Generators can produce carbon monoxide, hot surfaces, fuel hazards, moving-part hazards, and lethal voltage. Shut the generator down and do not open energized compartments unless qualified.
