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.
