Customer Question
Our Onan 5500 lp...

Our Onan 5500 lp generator keeps turning off in the middle of the night. We added oil. It started and then turned off again.

Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

Yes there is fuel in the tank. There are two tanks and it switches automatically from one tank to the next. The fuel I suppose is clean as we just filled the bottles.

Mechanic's Assistant: Do you plan on doing the work yourself?

We would rather not. However, we are in a rural area and repairmen are not nearby.

Mechanic's Assistant: Anything else we should know to help you best?

No, I don't think so. We are new RV owners and pretty clueless about all of this.

Hello, my name is ***** ***** I am going to assist you with this.

What is the full model number of the genset?

Ask Your Own Small Engine Question
Customer reply replied 10 months ago
Onan 5500 LP. We think it may be a switch problem, not switching tanks when one is empty. We just hooked it up to a big propane bottle and it came on. Or, maybe it is a problem with the hose.
Customer reply replied 10 months ago
No, I prefer to communicate this way because I am at work.
Technician: Hank F., Technician replied 10 months ago

I need to know the model number. 5500LP is not a model.

Ask Your Own Small Engine Question
Customer reply replied 10 months ago
Where would the model number be on the unit.
Technician: Hank F., Technician replied 10 months ago

That depends on which model it is, but there will be a sticker or a metal tag somewhere on the front of the unit.
