Onan generator running but no output or breaker/load problem

Cummins Onan quick-start, service FAQ, and power-basics guidance point owners to reduce combined wattage, avoid too many appliances at once, and use normal breaker reset steps before calling for service when generator output is missing.

Owner-safe checklist

  • Turn off heavy appliances before retrying the generator output.
  • Compare appliance running watts against the generator rating and start large loads one at a time.
  • Use only the normal accessible breaker or coach controls described for the RV.
  • Call a qualified technician if the breaker trips again, output does not return, or electrical burning odor is present.
