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.
