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.
