TROUBLESHOOTING GUIDE
Possible Remedies: (Unplug stove first when possible)
Refill the hopper.
If the stove is on the low setting, you may need to close the damper
all the way. Slide the air supply control toward the minimum setting.
Remove the burn pot and clean it thoroughly.
Follow all cleaning procedures in the maintenance section of the
owner's manual.
Remove the auger motor from the auger shaft and try to run the
motor separately by pressing the fuel feed button on the control
board. If the motor turns, the shaft is jammed on something. If the
motor does not turn, the motor is defective or there is a faulty
connection with the control board. To remove the auger motor, take
the rear panel off the stove body. Loosen the two screws holding
the motor to the auger shaft.
Remove the auger shaft from the auger housing. Start by emptying
the hopper. Take the rear panel off the stove body. Then take the
auger motor off by removing the screws that hold the motor to the
auger shaft. Once the motor is out, remove the four screws on the
steel plate that holds the auger shaft to the auger housing. Then
rotate the bottom end of the auger shaft down towards you until you
can pull the shaft down out of the stove. After you have removed the
shaft, inspect it for bent flights, burrs, or broken welds. Remove any
foreign material that may have caused the jam. Also, check the
auger housing for signs of damage such as burrs, rough spots, or
grooves cut into the metal that could have caused a jam. Clean the
auger housing thoroughly to remove all pellet dust.
The thermistor is a heat sensor located on the exhaust housing. Its
function is to tell the control board that the unit has ignited properly
by measuring the heat in 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 bad, the unit will stop after the ignition cycle. If this situation
occurs, call your dealer or technician.
