The burnpot holes are blocked.
The air inlet, the interior chambers, or exhaust
system has a partial blockage.
The hopper safety switch has failed or hopper
is open.
The auger shaft is jammed.
The auger motor has failed.
The Proof of Fire (POF) thermodisc has
malfunctioned.
The control board is not sending power to

TROUBLESHOOTING GUIDE
Possible Remedies: (Unplug stove first when possible)
Refill the hopper.
If on the low setting, you may need to close the dampener
all the way.
Remove the burnpot and thoroughly clean it.
Follow all cleaning procedures in the maintenance section
of the owner's manual
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.
"Start by emptying the hopper. Then remove the auger
motor by removing the auger pin, then remove the two
bolts that hold the auger bracket to the auger tube. The
auger bracket will now be able to be removed form the
auger tube. Remove the two bolts on the side of the auger
tube to remove the lower bearing of the auger. Pull the
auger out of the tube to free the jam.
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.
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 fire went out the
auger will continue to feed pellets until the hopper is empty
if you leave the POF thermodisc bypassed.
There should be a 5-volt (approximately) current going
to the POF thermodisc after the stove has been on for 10
minutes.
