TROUBLE SHOOTING GUIDE
Stove Feeds Pellets, But Will Not Ignite
Possible Causes Possible Remedies: (Unplug stove rst when possible)
Air damper open too far for
ignition.
Push the air damper left for startup. In some situations it may be necessary to have
the damper completely closed for ignition to take place. After there is a ame, the
damper can then be adjusted for the desired feed setting.
Blockage in igniter tube or inlet
for igniter tube.
Find the igniter housing on the backside of the rewall. The air intake hole is a small
hole located on bottom side of the housing. Make sure it is clear. Also, look from the
front of the stove to make sure there is not any debris around the igniter element
inside of the igniter housing.
The burnpot is not pushed
completely to the rear of the
rebox.
Make sure that the air intake collar on the burnpot is touching the rear wall of the
rebox.
Bad igniter element.
Put power directly to the igniter element. Watch the tip of the igniter from the front of
the stove. After about 2 minutes the tip should glow. If it does not, the element is bad.
The control board is not sending
power to the igniter.
Check the voltage going to the igniter during startup. It should be a full current. If the
voltage is lower than full current, check the wiring. If the wiring checks out good, the
board is bad.
Stove Will Not Feed Pellets, But Fuel Feed Light Comes On As Designed
Possible Causes Possible Remedies: (Unplug stove rst when possible)
High limit switch has tripped or
is defective.
Wait for the stove to cool for about 30 - 45 minutes. Locate the High Limit thermodisc
and press the reset button on the back of it. If the heater will not restart, check the
thermodisc to see if it’s bad. To test if the thermodisc is bad, you can bypass it as
described previously for the POF thermodisc.
Bad Auger Motor.
Remove the auger motor from the auger shaft and try to run the unit. If the motor will
turn, the shaft is jammed on something. If the motor will not turn, the motor is bad.
Auger Jam.
Start by emptying the hopper. Then remove the auger motor by removing the auger
pin. Remove the auger shaft inspection plate in the hopper so that you can see the
auger shaft. Gently lift the auger shaft straight up so that the end of the auger shaft
comes up out of the bottom auger bushing. Next, remove the two nuts that hold the
top auger biscuit in. Then rotate the bottom end of the auger shaft up towards you
until you can lift the shaft out of the stove. After you have removed the shaft, inspect
it for bent ights, burrs, or broken welds. Remove any foreign material that might
have caused the jam. Also, check the auger tube for signs of damage such as burrs,
rough spots, or grooves cut into the metal that could have caused a jam.
Loose wire or connector.
Check all wires and connectors that connector to the auger motor, high limit switch,
and the Molex connector.
Bad control board.
If the fuse is good, the wires and connectors check out good, and the high limit switch
did not trip, test for power going to the auger motor. If there is not a full current going
to the auger motor when the fuel feed light is on, you have a bad control board.
