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. If the fuse 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 thermodisk. To test if the thermodisk is bad, you can
bypass it as described previously for the POF thermodisk.
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.
