STOVE SHUTS OFF AND THE #3 LIGHT FLASHES
Possible Causes
The hopper is out of pellets.
The air damper is too far open for a low feed setting.
The burnpot is not pushed completely to the rear of the
firebox.
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 high limit thermodisc has tripped or is defective.
The fuse on the control board has blown.
The control board is not sending power to the POF
thermodisc or other auger system components.

Possible Remedies: (Unplug stove first when possible)
Refill the hopper.
If burning on the low setting, you may need to close the
damper all the way (push the knob in so it touches the side of
the stove).
Make sure that the air intake collar on the burnpot is touching
the rear wall of the firebox.
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. Remove the auger shaft inspection
plate in the hopper so that you can see the auger shaft. Gently
lift the auger shaft straight up so that the end of the auger shaft
comes up out of the bottom auger bushing. Next, remove the
two nuts that hold the top auger biscuit in. Then rotate the
bottom end of the auger shaft up towards you until you can lift
the shaft out of the stove. After you have removed the shaft,
inspect it for bent flights, burrs, or broken welds. Remove any
foreign material that might have caused the jam. Also, check
the auger tube for signs of damage such as burrs, rough spots,
or grooves cut into the metal that could have caused a 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 brown wires and connecting them with a short piece of
wire. Then plug the stove back in. 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.
Wait for the stove to cool for about 30 - 45 minutes. Locate the
High Limit thermodisc and press the reset button on the back
of it. If the heater will not restart, check the thermodisc to see
if it's bad. To test if the thermodisc is bad, you can bypass it as
described previously for the POF thermodisc.
Remove the control board. On the back there is one fuse. If it
appears to be bad, replace it with a 5 Amp, 125 Volt fuse. Plug
the stove back in and try to run the unit.
There should be a 5-volt (approximately) current going to the
POF thermodisc after the stove has been on for 10 minutes.
