Onan OIL TEMP-PRESS fault code — Generator
Applies to: Quiet Diesel 3200 HDZAA Spec A-E, Quiet Diesel 3200 HDZAA Spec F
What OIL TEMP-PRESS means
The Cummins Onan Quiet Diesel 3200 operator manuals list OIL TEMP-PRESS as engine lubricating oil temperature is too high or oil pressure is too low.
Owner-safe checks
- Stop the generator and let it cool.
- Check oil level only with the unit off and cool.
- Check only exterior air intake blockage from outside the generator area.
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.
