Aqua Hot Diesel Not Lighting

[Aqua Hot Diesel Not Lighting]

I have a 2015 Fleetwood Providence.  I have the 400D Aqua Hot.  On the electric side, hot water and electric heat to Zone 3 work fine.  When engaging the Burner Switch, light comes on, blower comes on, however, I do not hear ignitors, no smoke from the exhaust and no smell of diesel. 
After about 30 seconds the light goes out on the Burner Switch.  I would surmise, that with no ignition (popping sound) and/or smell of diesel, this may be electrical.  I am getting ready to take to dealer, any last minute suggestions.  Tank is full, there are no red lights on the panel.

 

Thanks 

[RV taxes in Arkansas]

Have purchased a 2015 Fleetwood 42M and reside in Hot Springs, Arkansas.  I have had my motorhome assessed but there appears that no one knows what the millage rate is, or what the approximate tax liability will be incurred come tax time.  I have been to the website, and that part of the assessments is under construction.  If there are any persons who have any knowledge of this, I would appreciate some direction.
