System Snap Disk Fault

Fault light and #4 heat indicator blinking.

This fault code is caused by a heat sensitive switch that tells the control

board if the appliance is hot or cold. During operation if the unit runs

out of pellets or looses its fire this switch will communicate to the control

board that the stove is getting cold. The control board will shut off the

auger functions and initiate a twenty minute combustion fan safety cool

down. Another condition that will trigger this fault code is a failed start.

When the appliance is started the control board initiates a 30 minute

timer, if the appliance is cold at the end of this 30 minute start up timer

the control board will indicate a #4 fault and initiate a 20 minute

combustion fan cool down.

Likely causes:

• Unit ran out of pellets.

• Fire went out during operation.

• Unit was cold at the end of a start cycle (fire did not light).

• Faulty snap disk.
