What is Code 33 on an Onan generator?
Onan Generator Code 33 Causes That shut down occurs when the generator is overheating. One of the causes for this code is that the overheat sensor may be malfunctioning.
How to find fault code on Onan genset?
The light will flash (X) number of times, pause for 1 second, and flash for (X) number of times again. Count the flashes before and after the pause. This will be the Fault Code. Example: 2 rapid flashes, 1 second pause, 5 rapid flashes is a Fault Code 25. There may be more than one Fault Code stored, so watch the light very carefully.
What to do if your Onan controller won’t start?
Go to the genset and use the switch on the set itself. Press ‘Stop’ 3 times within 5 seconds. The light in the switch will start flashing. If the light flashes 3 times, pauses for 3 seconds, and flashes 3 more times, press and immediately release ‘Stop’ one more time. This will put the controller into Fault Read Mode.
Can a genset have more than one fault code?
There may be more than one Fault Code stored, so watch the light very carefully. If there is more than one code, it will display them all in order, and then start over again. Be very careful not to misread a first level fault code (single digit code) as a seconds level fault code (double digit code).
What does it mean when the genset controller blinks?
The genset controller provides extensive diagnos- tics by causing the status indicator light on the Con- trol Switch to blink in a coded fashion. Following a fault shutdown, the indicator light will repeatedly blink 2, 3 or 4 blinks at a time. • Two blinks indicates a low oil pressure fault. • Three blinks indicates a service fault.
Why does my Onan genset have a code 33?
I tried unhooking the batteries to clear the memory, but no luck Thanks Jim Code 33 is High Engine Coolant Temperature. If the set is not running, it is obviously not overheating. But this code will not normally prevent the set from starting. Usually, the set will run for about a minute, and then shut down.
