Heil 80% EFF--- Fires, runs, Shuts off!!
 
Heil Model # NTG3075FBGT, Gas, Forced Hot Air,
80% exhaust into chimney, Calls for heat, Fires, and shuts off. Checked exhaust Air Switch. Checks OK. Checked 3 Roll out switches, by bypassing them, and they all check OK. It is Pilotless, and fires with a Spark igniter, and that all seems to work OK. Is my next move to check the Flame sensor,(if there is one) or what? Please help,
Mark

How old is this unit. Post a pic of the burner area. Some of them use a combination pilot burner/sensor which is not always cleanable. I usually replace the pilot burner assembly. May also have a circuit board problem.

. Your model number come up here.
I believe your board is the likeliest of culprits.

Remove the spark igniter and flame rod and clean them with emory cloth and reinstall them.
