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.
