Possible Causes
The convection blower is overheating and
tripping the internal temperature shutoff.

extended periods of time.
Fuel other than wood pellets is being burned in
the stove.
Power surge or brown out situation.
High limit switch is malfunctioning.
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. Check to see if a surge protector is being
used on the stove. If not, recommend one to the consumer.
If the other items check out OK, replace the high limit switch.
