CONTROL BOARD
Possible Causes:
1. Inadequate fuel is used.
2. The igniter is defective.
3. The thermistor heat sensor has
malfunctioned.

Possible Remedies:
Remove the burn pot, make sure that all openings
are clear and check that no ash has filled the tube
around the igniter. Refer to the maintenance section.
Also, make sure that recommended fuel is used (see
Section 4.8.1: Proper Fuel).
See Section 8.2: Testing a Component and follow
instructions for component check. Test the igniter to
see if it glows. It should take no longer than two
minutes. If it does not glow red, check the wiring and
the F3 fuse. If the wiring is properly connected and
the fuse is good, disconnect the igniter and check its
resistance (ohms, Ω) with a multimeter. If the value is
near zero, replace the igniter.
The "thermistor" is a heat sensor located on the
exhaust motor housing. Its function is to tell the
control board that the stove has ignited properly by
measuring the heat at the exhaust. The pellet stove
will not start feeding pellets at the desired heat setting
until it has received a signal from the thermistor heat
sensor. If the thermistor heat sensor is faulty, the unit
will stop after the ignition cycle.
temperature reading from the thermistor press and
hold the + and auger buttons for 3 seconds. Confirm
that the value displayed is equal to the ambient
temperature in the room where the appliance is
installed. If this is the case, turn on the stove and
check the same temperature display. If after 10
minutes, the value has not increased despite the unit
is in operation this means that the temperature
sensor is disconnected
temperature rises, the problem may be with the feed
rate or pilot mode. Depending on many factors
(ambient temperature, pellet quality, etc) the heat
produced by the stove may not be sufficient to keep
the exhaust temperature high enough. To resolve the
situation increase feed rate or replace the part (see
Section 5.2.2: Adjusting the Convection Fan
Speed).
