3. Defective igniter element.
4. The thermistor heat sensor has malfunctioned.
5. The control board is not sending power to the igniter.
STOVE FEEDS PELLETS, BUT WILL NOT IGNITE AND

Possible Remedies:
Adjust the air supply to the minimum setting for startup. In some
situations, it may be necessary to have the damper completely
closed for ignition to take place. Once there is a flame, the damper
can be adjusted to the desired feed setting.
Remove the burn pot and clean it thoroughly. Make sure that all
openings are clear. Find the place where the igniter tube comes out
of the burn pot housing. It is a small tube located on the back of the
burn pot housing. Make sure it is clear. Make sure there is no debris
around the igniter element or inside the igniter tube.
Supply power directly to the igniter element. Watch the tip of the
igniter from the front of the stove. After about 2 minutes, the tip
should glow. If it does not, the element is defective and must be
replaced. You may need a technician to perform this test.
The thermistor is a heat sensor located on the exhaust housing. Its
function is to tell the control board that the unit has ignited properly
by measuring the heat in the exhaust. The pellet stove will not start
feeding pellets at the desired heat setting until it has received a
signal from the thermistor heat sensor. If the thermistor heat sensor
is bad, the unit will stop after the ignition cycle. If this situation
occurs, call your dealer or technician.
Check the voltage going to the igniter during ignition. It should be a
full current. If the voltage is lower than full current, check the wiring.
If the wiring is functional and properly connected, the board is
defective. You will need a technician to perform this test.
APPEARS ON THE CONTROL BOARD
Possible Remedies:
Remove the control board and check at the back to see if the F3
fuse appears to be bad. Replace it with a 5 Amp 250V fuse. Plug
the stove back and try to run the unit.
APPEARS ON THE CONTROL BOARD
Possible Remedies:
Using the owner's manual, locate the L-250 high temperature
switch. There is a red button located on the back of it. Press the
red button. If you hear a click, the high limit had tripped. Reset the
stove. The stove should now function normally. YOU NEED TO
INSPECT YOUR UNIT AT THIS POINT. The F-250 high
temperature switch will trip if the unit overheats. There might be a
problem with another component or the installation, causing the
stove to overheat. Make sure that the convection blower works. If
the convection blower has failed, this can cause the unit to overheat.
Clean any dust off of the windings and blades of the convection
blower. Call your dealer or a technician if you get this code again.
