Possible Causes Possible Remedies: (Unplug stove rst when possible)
The hopper is out of pellets. Rell the hopper.
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.
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. 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.
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 re went out, the auger will continue to feed pellets until the
hopper is empty with 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.
The rebox is not properly
sealed.
Make sure the door is closed and that the gasket is in good shape.
Vent pipe is incorrectly
installed.
Check to make sure vent pipe installation meets criteria in owner’s manual.
Airow switch wire
connections are bad.
Check the connectors that attach the gray wires to the air switch.
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.
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.
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.
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 rst 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.
