Trouble Shooting Guide

Possible Remedies: (Unplug stove first when possible)
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.
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.
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 flights, 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.
Check all wires and connectors that connector to the auger
motor, high limit switch, and the Molex connector.
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.
Possible Remedies: (Unplug stove first when possible)
Clean any dust off of the windings and fan blades. If oiling
the blower does not help, the blower may be bad.
If operating the heater on the highest heat setting, the room
temperature could increase enough and lead to potential
overheating situations. If this happens, try operating at a
lower heat setting.
This pellet stove is designed and tested to use wood pellets.
Check for signs of fuel other than wood pellets. No other
types of fuel have been approved for this pellet stove. If
there are signs of other types of fuel being used, stop using
them immediately.
A power surge, spike, or voltage drop could cause the high
limit switch to trip. Use a surge protector.
If the other items check out OK, replace the high limit switch.
