Possible Cause
Corrective Action
1 Flash: Empty
Hopper
No fuel is delivered to the fire pot 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,
fire pot, and behind the baffles. Inspect the
exhaust probe to see if it is securely attached
to the side of the exhaust outlet.
2 Flashes: Exhaust
Probe Fail
The exhaust probe
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.
Exhaust Probe Failure
Not plugged in
Failed component
Plug the probe into the board
Replace the component
3 Flashes: Ambient

The ambient probe
senses a temperature
of less than negative
20 degrees Celsius
or above 70 degrees
Celsius.
