TROUBLE SHOOTING GUIDE
Convection Blower Shuts Off And Comes Back On
Possible Causes
Possible Remedies: (Unplug stove first when possible)
The convection blower is
overheating and tripping
the internal temperature
shutoff.
Clean any dust off of the windings and fan blades. If cleaning the blower
does not help, the blower may be bad.
Circuit board malfunction.
Test the current going to the convection blower. If there is power being
sent to the blower when it is shut off, then the control board is fine. If there
is NOT power being sent to the blower when it shuts off during operation,
then you have a bad control board.
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.
