TROUBLESHOOTING GUIDE
Stove Will Not Feed Pellets, But Fuel Feed Light Comes On As Designed
Possible Causes
Possible Remedies: (Unplug stove first 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 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.
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.
