What causes a Onan generator to overheat?
If the generator set is not properly ventilated, it may overheat and affect its performance. Long periods of overheating may cause the generator set to shut down and may ultimately damage the equipment. A possible design methodology is to use a door vent to allow for dedicated cooling air inlet to the generator.

What causes a generator to shut down at low oil level?
This can be caused by low fuel level (not getting gas), vapor lock (too hot, gas is boiling), fuel contamination (water or dirt in fuel and/or filter) or a faulty fuel pump (insufficient fuel pressure). Models equipped with low oil level (LOL) switches will shut down the engine on low oil level.
What happens when you turn off the genset?
This is what happens when you stop your genset. Pressing and holding the stop switch for a few seconds causes the control board to cut off the 12 volts to the ignition and fuel pump (and/or fuel solenoid valve) causing the engine to stop. On models equipped with magneto ignition, the control board grounds the magneto kill circuit.
