The air inlet,the interior chambers,
or the exhaust system has a partial
blockage.
The auger shaft is jammed.
The auger motor has failed.
The low limit switch has
malfunctioned.
The fuse on the control board has
blown.
The control board is not sending

APPLIANCE SHUTS OFF AND #4 .LIGHT FLASHES.
The high limit switch has tripped.
APPLIANCE FEEDS PELLETS BUT WILL NOT IGNITE
Blockage in igniter tube or inlet for
the ignitor tube.
The burnpot is not seated
completely into the burner housing.
Defective ignitor.
The control board is not sending
power to the ignitor.
SMOKE SMELL IS COMING BACK INTO THE HOME
There is a leak in the vent pipe
system
The gasket on the combustion
blower has deteriorated.
NOTE: When the green light flashes it is indicating it is in pilot mode, or low burn. The heat level setting light
will not change, and will still display the current manual setting of heat level. The only way to indicate that they
are in pilot or low burn is when the power light is flashing green.

Refi ll the hopper.
-
Close the hopper lid
-
Insure the burnpot locating notch engages with the ignitor and that the burnpot sits fl at.
-
Remove the burnpot and thoroughly clean it.
-
Follow all cleaning procedures in the maintenance section of the manual.
-
Start by disconnecting the power supply and emptying the hopper.
-
- The auger shaft may be jammed. For more information see "JAMMED AUGER" section.
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 defective.
Temporarily bypass the low limit switch by disconnecting the two brown wires and
-
connecting them together with a short piece of wire, then plug the appliance back in.
If the appliance comes back on and works, you need to replace the low limit switch.
CAUTION: This is for testing only! Leaving the switch bypassed will cause the blowers
to remain on constantly and the auger will continue to feed even if the fi re is out. Do not
operate the unit with the low limit switch bypassed.
Remove the control board. If the fuse appears to be defective, replace it with a 5 amp
-
125 volt fuse. Plug the appliance back in and try to run the unit.
There should be an approximate 5 volt current going to the low limit switch after the
-
appliance has been on for 10 minutes.
- Feed rate is too low for the quality and moisture content of pellet fuel that is being used.
Adjust trim of combustion blower down or auger motor up.
This is a manual reset switch but should only be done by a qualifi ed technician once the
-
cause of failure has been determined.
Ensure that the air intake hole is clear, it is located on the side of the igniter housing on
-
the back of the fi rewall.
Place the burnpot so that the locating notch engages with the ignitor and the burnpot is
-
sitting fl at
Put power directly to the ignitor and observe the tip of the ignitor from the front of the
-
appliance. Within two minutes the tip should glow, if it does not, the ignitor is defective.
Check the voltage going to the ignitor during start up. It should be at full current (115
-
volts). If the voltage is lower than full current, check for problems with the wiring. If no
problems are found, the board is defective.
Inspect all the vent pipe connections. Make sure they are sealed with RTV silicone that
-
has a temperature rating of 260°C (500°F) or higher. Seal joints with UL-181-AP foil
tape and insure the square to round adapter piece on the combustion blower has been
properly sealed with the same RTV.
Inspect both gaskets on the combustion blower to make sure they are in good shape.
-
Replace if necessary.
