TROUBLESHOOTING GUIDE
Stove Will Not Feed Pellets, But Fuel Feed Light Comes On As Designed
Possible Causes
High limit switch has
tripped or is defective.
Bad Auger Motor.
Auger Jam
Loose wire or connector.
Bad control board.
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.
