Onan OVER TEMPERATURE (INVERTER) fault code — Generator

Applies to: Quiet Diesel 3200 HDZAA Spec A-E, Quiet Diesel 3200 HDZAA Spec F

What OVER TEMPERATURE (INVERTER) means

The Cummins Onan Quiet Diesel 3200 operator manuals list OVER TEMPERATURE (INVERTER) as the inverter temperature exceeded its limit.

Owner-safe checks

  • Reduce loads and let the generator cool.
  • Check only exterior airflow obstruction from normal access points.

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.
