STOVE SHUTS OFF AND THE # 3 (POF) LIGHT FLASHES
– One of the thermodisc deactivated or failed to activate on start-up
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 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).
3.
The burnpot is not pushed completely to the rear of the firebox.
Make sure that the air intake collar on the burnpot is touching the
rear wall of the firebox.
4.
The burnpot holes are blocked.
Remove the burnpot and thoroughly clean it.
5.
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.
6.
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.
7.
The auger shaft is jammed.
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.
8.
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.
9.
The Proof of Fire (POF) thermodisk has malfunctioned.
Temporarily bypass the POF thermodisk 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 thermodisk. 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 thermodisk bypassed.
10. The high limit thermodisk has tripped or is defective.
Wait for the stove to cool for about 30 - 45 minutes. It should now
function normally. If not use the owner’s manual to locate the high
limit thermodisk. To test if the thermodisk is bad, you can bypass it
as described previously for the POF thermodisk.
11. The fuse on the control board has blown.
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.
12. The control board is not sending power to the POF thermodisk
or other auger system components.
There should be a 5-volt (approximately) current going to the POF
thermodisk after the stove has been on for 10 minutes.
