Pellet Fines may
build up in this
area
The low draft sensor which is a vacuum differential switch, monitors the negative pressure (draft) in the firebox through
a port on the rear of the feeder. Poor draft will result in an interruption of power to the feeder motor. Poor draft can be
caused by blockage in the exhaust, excessive build-up on the combustion blower fan blades, a failed combustion blower,
or a door or other opening to the firebox not sealed properly. The circuit board is monitoring the position of this switch.
During a feed cycle, if this switch were to open, the feed motor light on the control will stay illuminated with the power
being interrupted by the switch. If the switch opens when the cycle is at rest, the power light for the feed motor will not
illuminate. Be sure all doors, including the hopper lid, are securely closed when operating the appliance.
