AH was serviced last fall as far as I know.  Haven't run diesel burner since April.  Fuel gage reflects over 1/2 tank.

AH needs to be run monthly at a minimum.  I suspect your nozzle has clogged with gelled fuel.  Time for a service, replace nozzle, clean the combustion chamber, check the electrodes, flame detector, etc.

Hope this helps
