OWNER´S MANUAL
CONVECTION BLOWER SHUTS OFF AND COMES BACK ON
Possibles Causes
1.-The convection blower is overheating and
tripping the internal temperature shutoff.
2.Circuit board malfunction.
STOVE WILL NOT FEED PELLETS, BUT FUEL FEED LIGHT COMES ON
AS DESIGNED
Possibles Causes
1. Fuse on control board blew.
2. High limit switch has tripped or is defective.
3. Bad auger motor.
Possibles remedies (Unplug stove first
when possible)
Try lubricating the convection blower. Put 1-2
drops of SAE 20 oil in each of the two oiling
ports. Also, clean any dust off of the windings
and fan blades. If oiling the blower does not
help, the blower may be bad.
Test the current going to the convection blower.
If there is power being sent to the blower when
it is shut off, then the control board is fine. If
there is NOT power being sent to the blower
when it shuts off during operation, then you
have a bad control board.
Possibles remedies (Unplug stove first
when possible)
Remove the control board. If the fuse appears
to be bad, replace it with a 5 Amp 250 Volt
Fuse. Plug the stove back in and try to run the
unit.
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.
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.
