I have an Onan 3600 LP generator in my horse trailer. The generator and trailer were purchasd new in April 2016. The generator will not start. It gives me a service code of 15. Until the day it did not start I have not had any problems with it. The battery is good.

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

Since your unit is brand new, it is still under warranty, and you are going to be very limited in what you can do without voiding your warranty.

However, by setting a code 15, and now not even starting, this points heavily to a lack of fuel

Make sure your LP tank is full and turned on.

If the unit had run out of LP, or you had changed tanks, there may be air in the line. Make sure all air is purged from the line.

If it still will not start, check to see if you are getting spark to the plug.

Let me know what you find.
