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.
