Possible Causes Possible Remedies: (Unplug stove rst when possible)
1. The air inlet, burnpot, interior combustion air
chambers, combustion blower, or exhaust pipe
are blocked with ash or foreign material.
Follow all cleaning procedures in the maintenance
section of the owner’s manual.
2. The Proof of Fire (POF) thermodisc has came
unplugged
Check the (POF) thermodisc to see if the wires are
connected properly.
3. The Proof of Fire (POF) thermodisc has
malfunctioned.
Temporarily bypass the POF thermodisc by
disconnecting the two wires and connecting them
with a short piece of wire. Then plug the stove back
up. If the stove comes on and works, you need to
replace the POF thermodisc. This is for testing only.
DO NOT LEAVE THE THERMODISC BYPASSED. Your
blowers will never shut off and if the re went out the
auger will continue to feed pellets until the hopper
is empty if you leave the POF thermodisc bypassed.
4. The hopper is out of Pellets. Rell the hopper.
5. The hopper safety switch has failed or hopper is
open.
When operating the unit, be sure the hopper lid is
closed so that the hopper safety switch will activate.
Check the wires leading from the hopper safety
switch to the control panel and auger motor for
secure connections. Use a continuity tester to test
the hopper safety switch; replace if necessary.
6. The auger shaft is jammed.
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 ights, 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.
7. The auger motor has failed.
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.
