TROUBLESHOOTING GUIDE 22
STOVE WILL NOT FEED PELLETS, BUT FUEL FEED LIGHT COMES ON AS DESIGNED
Possible Causes:
Possible Remedies:
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. It should
now function normally. If not, use the owner’s manual to
locate the high limit thermodisc. 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 some-
thing. 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 inspec-
tion plate in the hopper so that you 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.
4. Loose wire or connector Check all wires and connectors that connect to the auger
motor, high limit switch, and the Molex connector.
5. Bad control board If the fuse is good, the wires and connectors check out
good, and the high limit switch did not trip, test fir 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.
