Possible Causes
Possible Remedies: (Unplug stove first when possible)
The hopper is out of pellets
Refill the hopper.
The air dampener is too far open for a low feed
setting
If on the low setting, you may need to close the dampener all the
way.
The burnpot holes are blocked.
Remove the burnpot and thoroughly clean it.
The air inlet, the interior chambers, or exhaust
system has a partial blockage.
Follow all cleaning procedures in the maintenance section of the
owner's manual
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.
The auger shaft is jammed.
"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.
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.
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 fire went out the auger will continue to feed
pellets until the hopper is empty if you leave the POF thermodisc
bypassed.
The control board is not sending power to the POF
thermodisc or other auger system components.
There should be a 5-volt (approximately) current going to the
POF thermodisc after the stove has been on for 10 minutes.
