TROUBLE SHOOTING GUIDE
Control board not sending power to combustion
blower.
Control board not sending power to air switch.
Air switch has failed.
Display is Flashing "E3"
Possible Causes
The hopper is out of pellets
The air dampener is too far open for a low feed
setting
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
the POF thermodisc or other auger system
components.
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.
There should be a 5-volt current (approximately) going to the air switch
after the stove has been on for 30 seconds.
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.
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.
