Stove Will Not Feed Pellets, But Fuel Feed Light Comes On As Designed
Possible Causes
Possible Remedies: (Unplug stove first when possible)
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.
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.
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.
Loose wire or connector.
Check all wires and connectors that connector to the auger
motor, high limit switch, and the Molex connector.
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.
TROUBLESHOOTING GUIDE
High Limit Switch Keeps Tripping
Possible Causes
Possible Remedies: (Unplug stove first when possible)
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.
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.
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.
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.
High limit switch is malfunctioning.
If the other items check out okay, replace the high limit switch.
