Looks like I'm getting a fault code of 36 on my Onan 5500 generator

Mechanic's Assistant: Just to clarify, what's the exact code? And have you tried to reset it?

It's 36 how do I reset it?

Mechanic's Assistant: What is the model/year of your RV?

It's a Heartland Road Warrior 5th Wheel Toy Hauler 2011

Mechanic's Assistant: Are you fixing your RV yourself? What have you tried so far?

Yes I just looked up how to get the code and I got the code 36

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Well it just runs for awhile and then starts to make a clicking or tapping sound and dies

Hi, my name is ***** ***** I will be happy to assist with this today.In some cases, I may need more info to assist better.I apologize for any delay.
I am here Sundays through Thursdays from around 5 am to 2 pm Mountain time.If you respond and I do not respond back right away I will do so as soon as I can.

This code indicates the generator engine shut down without being commanded to shut down.In allot of cases, this can be a fault with a lack of fuel due to a restricted fuel filter leading to the generator or a fault with a weak fuel pump causing low fuel pressure.This can also be a fault with a damaged or kinked fuel line leading to the generator or dirty carburetor.In most cases, it is the fuel filter or fuel pump needs replaced.

You will need to have this looked into/tested further to locate which component is causing this fault then from there it can be repaired to resolve this issue here.A lean condition where it is running out of fuel due to this fault can cause the engine to make a click or tap noise.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service, your 5-star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.I work on delivering the best answer and help here but in some cases, it can be difficult to do without seeing the vehicle.

Thanks Pete
