Troubleshooting guide

When the stove shuts down and the number 3 LED light is blinking let’s look at the
simplest
solution first. The following 2 items are Operator error.
•
Open the hopper and see if the unit has run out of fuel.
If the hopper is empty, fill the hopper and re-light the stove.
•
Open the Main Door of the unit and look in the burnpot. Is there unburned fuel in
the burnpot? Unburned fuel in the pot usually means the stove is running on a low
setting and the damper is wide open. This causes the fuel to burn too fast during
low burn and the fire eventually goes out. Since the Proof of Fire Switch is still
closed at this point the auger will continue to feed pellets until the P.O.F. switch
drops out and the stove shuts down.
Adjust the damper for a low burn or Fine-Tune the level 1 feedrate using
the Feed Trim button. If the stove is hooked to a tall vertical Chimney
with good draft, use the Draft Trim button to adjust the combustion fan
voltage to compensate for extra draft.
The Draft adjustment listed above would not prevent the stove from re-lighting and may
be due to a failure to make the
initial start-up adjustments
after a new stove is installed.
When trouble shooting the components, keep in mind that the
High Limit (Stove
Overheating) and the Proof of Fire (Exhaust Temperatures too low) Switches
may
actually be sensing a problem in the unit and are not necessarily failing.
If the above mentioned items are not the cause
and all the corn in the burnpot is
burned up
, then the auger shut off before the fire went out in the burnpot, consuming all
fuel in the pot. Again let’s start with the simplest scenarios.
• First
turn the stove on and see if it feeds fuel during the start-up cycle.
ATTENTION:
The auger does not run during the first 5 minutes after the control
board is turned on and then starts to feed on the #1 level until the Proof of Fire
switch closes. Be sure to wait until the auger should be running or press the Auger
Button
.
If it doesn’t feed fuel, check the following:
Check to see if the Auger Motor is running, but the auger is not turning.
This may indicate either a
loose setscrew
on the auger shaft or a stripped
out
gearbox
.
If the Auger Motor tries to start and immediately stops usually means a
foreign object is stuck in the auger system or the Auger is jammed. Take a
quick look up the drop chute area in the front of the stove to make sure it’s
not jammed there. Dislodge anything that could be causing a jam.
