STOVE WiLL NOT FEED PELLETS, BuT FuEL FEED LighT COmES ON AS DESigNED
Possible Causes: Possible remedies: (unplug stove first when possible)
1. Fuse on control board blew. 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.
2. High limit switch has tripped or is defective. 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.
3. Bad Auger Motor. 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.
4. Auger Jam. 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.
5. Loose wire or connector. Check all wires and connectors that connector to the auger motor, high
limit switch, and the Molex connector.
6. Bad control board. If the fuse is good, the wires and connectors check out good, and the high
limit switch did not trip, test for power going to the auger motor. If there
is not a full current going to the auger motor when the fuel feed light is
on, you have a bad control board.

Possible Causes: Possible remedies: (unplug stove first when possible)
1. The convection blower is overheating and tripping the internal
temperature shutoff.
Clean any dust off of the windings and fan blades. If oiling the blower
does not help, the blower may be bad.
2. The stove is being left on the highest setting for extended periods
of time.
If operating the heater on the highest heat setting, the room temperature
could increase enough and lead to potential overheating situations. If this
happens, try operating at a lower heat setting.
3. Fuel other than wood pellets is being burned in the stove. This pellet stove is designed and tested to use wood pellets. Check for
signs of fuel other than wood pellets. No other types of fuel have been
approved for this pellet stove. If there are signs of other types of fuel
being used, stop using them immediately.
4. Power surge or brown out situation. A power surge, spike, or voltage drop could cause the high limit switch
to trip. Check to see if a surge protector is being used on the stove. If
not, recommend one to the consumer.
5. High limit switch is malfunctioning. If the other items check out OK, replace the high limit switch.
