Re: Onan starts and dies, throws Code 3
Fault 3 is a general code that indicates you need to check for a secondary code. After it does the 3 flashes, hit the off button only once and a secondary code will pop up. I'm having that issue right now with only 40 hours on the generator. Your crankcase should only be filled halfway between "ADD" and "FULL".4.3KViews0likes3Comments
