Possible Causes
Possible Remedies: (Unplug stove first when possible)
1.
The hopper is out of pellets.
Refill the hopper.
2.
The air damper is too far open for a low feed setting.
If on the low setting, you may need to close the damper all
the way.
3. The burnpot holes are blocked.
Remove the burnpot and thoroughly clean it.
4.
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.
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 two bolts that hold
the auger bracket to the auger tube. The auger bracket will
now be able to be removed from 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. Inspect auger before replacing.
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.
8. 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 with the
POF thermodisc bypassed.
9.
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.
3.
The firebox is not properly sealed.
Make sure the door is closed and that the gasket is in good
shape.
4.
Vent pipe is incorrectly installed.
Check to make sure vent pipe installation meets criteria in
owner’s manual.
5.
The airflow switch wire connections are bad.
Check the connectors that attach the gray wires to the air
switch.
6.
Combustion blower failure.
With the stove on, check to see if the combustion blower is
running. If it is not, you will need to check for power going to
the combustion blower. It should be a full current. If there is
power, the blower is bad. If there is not, see #7.
7.
Control board not sending power to combustion
blower.
If there is no current going to the combustion blower, check
all wire connections. If all wires are properly connected, you
have a bad control board.
8.
Control board not sending power to air switch.
There should be a 5-volt current (approximately) going to the
air switch after the stove has been on for 30 seconds.
9.
Air switch has failed.
To test the air switch, you will need to disconnect the air hose
from the body of the stove. With the other end still attached
to the air switch, very gently suck on the loose end of the hose
(you may want to remove the hose entirely off the stove and
the air switch first and make sure it is clear). If you hear a click,
the air switch is working. BE CAREFUL TOO MUCH VACUUM
CAN DAMAGE THE AIR SWITCH.
