STOVE FEEDS PELLETS, BUT WILL NOT IGNITE
AND SHOWS WARNING CODE "I"
Possible Causes:
1. The igniter fuse on the control board has blown.
STOVE STOPS FEEDING PELLETS AND SHOWS
WARNING CODE "O"
Possible Causes:
1. The L-250 manual reset high temperature switch has tripped.
Possible Remedies:
Adjust the air supply toward the minimum setting for startup. In some situations, it
may be necessary to have the damper completely closed for ignition to take place.
After there is a flame, the damper can then be adjusted for the desired feed setting.
Remove the burn pot and clean it thoroughly. Make sure that all openings are clear.
Find the igniter tube coming 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 not
any debris around the igniter element or inside the igniter tube.
Put 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 bad and must be replaced. You may need a technician to perform this test.
The thermistor is a heat sensor attached to the exhaust housing. Its function is to
tell the control board that the unit has ignited properly by measuring the temperature
in the exhaust. The stove will not feed 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 go out and 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 checks out
good, the board is bad. You will need a technician to perform this test.
Burn pot gaskets are located in the metal ring at the bottom of the burn pot. These
gaskets prevent heat lost from the igniters to get a fastest ignition.
Possible Remedies:
Remove the control board and check at the back to see if the F3 fuse is good,; if
not replace it with a 5 Amp 250V fuse. Plug the stove back and try to run the
unit.
Possible Remedies:
Using the owner's manual, locate the L-250 high temperature switch.
There is a red button on 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 blowers work. If one of the
convection blowers 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.
