8.
Control board not sending power to air switch.
9.
Air switch has failed.
Display is Flashing "E3"
Possible Causes
1. The hopper is out of pellets
2. The air dampener is too far open for a low feed setting
3. The burnpot holes are blocked.
4. The air inlet, the interior chambers, or exhaust system has
a partial blockage.
5. The hopper safety switch has failed or hopper is open.
6. The auger shaft is jammed.
7. The auger motor has failed.
8. The Proof of Fire (POF) thermodisc has malfunctioned.
9. The control board is not sending power to the POF
thermodisc or other auger system components.
Display is Flashing "E4"
Possible Causes
1.
The air inlet, burnpot, interior combustion air
chambers, combustion blower, or exhaust pipe are
blocked with ash or foreign material.
2.
The Proof of Fire (POF) thermodisc has came
unplugged

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.
Possible Remedies: (Unplug stove first when possible)
Follow all cleaning procedures in the maintenance section
of the owner's manual.
Check the (POF) thermodisc to see if the wires are
connected properly.
