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.
Plug the probe into the board
Replace the component

Fill the hopper
Inspect and clear jam in the feed tube
Inspect the feed motor circuit (hopper lid must be
closed, vacuum switch must be closed (ie. exhaust
blower on), and feed motor must be plugged in.
Clean the firepot
Check leads and if the igniter works. Clean the end of
the igniter chamber from inside the firebox (removal of
the firepot required for this step).
Review the feed motor and feed rates. Normal feed
motor operation is on between 1* and 4* seconds out
of every 7 seconds. (*Depending on model and burn
rate setting)
If the feed motor does not turn off, replace the control
board.
Review the fuel being used.
