No fuel is delivered to the firepot to
sustain flame
Hopper empty (most likely)
Auger Jam (next likely)
No vacuum
Hopper lid open
Flame is evident but the exhaust probe is not
able to recognize the hot exhaust temperature
Exhaust probe not attached to outlet
Exhaust path is dirty
Fill the hopper, inspect the feed tube for jams,
inspect the venting and firebox for obstructions
and clean if necessary, inspect the exhaust
blower to make sure it runs, or close the hopper
lid.
Inspect and clean the exhaust outlet, firebox,
firepot, and behind the baffles. Inspect the
exhaust probe to see if it is securely attached to
the side of the exhaust outlet.
2 Flashes:

senses a temperature
of less than negative
20 degrees Celsius
or above 300
degrees Celsius.
The exhaust temperature is above or below
the acceptable range.
