Question 2…

Why do I have to hold the start button down for so long before my Onan generator will start?

Both petrol and diesel Onan generators have a priming pump. The pump bleeds any air from the system assisting in easy starting for the generator. If your generator is cranking but not starting check that there is fuel and that your filters are clean.

Ensure your generator is serviced as per the manufacturers service schedule.

If any fault codes are being displayed refer back to your owners manual or contact your nearest authorised Onan service centre.

Empire have a range of general parts and service kits available for Onan generators via our shop.
