Troubleshooting

Check out our written guides here:
CAUTION!
Whenever performing maintenance on your stove, ensure that the stove is cool to the touch, and that
power has been disconnected.
Fault codes and error messages can be cleared off of the main screen by pressing and holding the
On/Off button for 5 seconds. (This acknowledges the error, and allows the stove to be restarted)
Problem: Total Loss of Power at the Control Panel
A total power loss at the panel indicates that the flow of electricity has been interrupted.
The flow of electricity follows this path: Main power cord > rear switch block > wiring
harness > main circuit board > data cable > control panel.
Solutions:
Ensure that the electrical outlet is working properly.
Ensure that the power switch is set to the On position (The -- is On, the 0 is Off)
Ensure that all of the wires and connections are secure at the power switch, circuit
board, and control panel.
Check the fuse at the back of the main power switch block. (There is an active and
backup fuse located in a pull-out tray. The active fuse is in the saddle, while the
backup fuse is in the plastic sleeve)
Problem: Alarm - Low Temperature (Check Hopper/Burn Pot Message)
When the low temp alarm occurs, it means that the computer has lost communication
to the proof of fire switch (POF). This usually happens because the fire got too small or
went out to embers. A handful of reasons can account for this happening, but the most
common is feeder interruptions. (Caused by low pellets in the hopper, or the hopper lid
being left open too long during refueling, for example)
Solutions:
Ensure that the hopper is not too low, or that the pellets are not bridging or creating
a funnel at the auger mouth opening. (This can cause low density of pellets, and
inconsistent feeding)
Check the Ash Cleaning Cycle (see Settings). This cycle may need to be
shortened on the lower levels.
Ensure that the safety switches are staying engaged during operation. (for
example: if the hopper lid is left open, the auger will not feed, resulting in this alert)
For chronic issues, switch the leads over to the backup POF switch at the exhaust
housing.
