STOVE FEEDS PELLETS, BUT WILL NOT IGNITE AND APPEARS ON THE
CONTROL BOARD
Possible Causes: Possible Remedies:
1. Inadequate fuel is used. 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).
2. The igniter is defective. 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.
3. The thermistor heat sensor has
malfunctioned.
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. To
display the 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
or defective. If the 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
