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 pellets.
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. Are there unburned
pellets in the burnpot? Unburned pellets in the pot usually means the stove is
running on a low setting and the damper is wide open. This causes the pellets 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 troubleshooting 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 pellets in the burnpot are
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 pellets during the start-up cycle.
ATTENTION: The auger will only run for 2 minutes after the control board is
turned on and then shuts off to complete the ignition cycle. Be sure to check it
during the initial 2 minutes.
If it doesn’t feed pellets, 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 on
pellets. First take a quick look up the drop chute area in the front of the
stove to make sure it’s not jammed there. Dislodge the pellets if a jam is
found.
