TROUBLESHOOTING 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 okay, replace the high limit switch.
