If the blower is running and the stove has been in use for some time, check
the blower for a build-up of dust, lint or pet hair. When the squirrel cage
gets dirty, it can’t move the proper amount of air and the stove could
overheat and shut down.
If the switch has been reset and the auger does not come on the next time
you start the stove, remove the 2
Orange
wires from the switch and check
the switch for continuity. Replace if it’s defective.
Unplug the
Orange
wires and check for voltage at the
Orange
wires.
First Generation Digital Control Boards have Line Voltage on that
circuit. Second and Third Generation Digital Control Boards have 5
volts DC. (First Generation Control Boards do not have the Thermostat
Slide Switch on the front of the board .All other generations have the slide
switch.)
If there isn’t any voltage on any of the
Orange
wires,
carefully
check for
voltage on the pin-out on the control board. If no voltage is present on the
control board the control board is bad and needs to be replaced.
Remember: There will only be voltage on one pin at the control
board.
If the switch is not defective, check to make sure the
Orange
wires are
inserted properly into the Molex connector that plugs into the control
board. They may appear to be inserted properly, but sometimes are not
connected to the pins on the control board. Push the 2 Orange wires into
the Molex connector to ensure they are seated properly.
If they are inserted properly, use an OHM meter and check both
Orange
wires for continuity.
As a last resort the control board should be replaced. If this problem is
intermittent, it most likely is not the control board.
Remember: Once the stove is turned on, both fans come on for 30 seconds, and then
the room fan shuts off and goes into a Start-up Cycle. If the high limit switch is
tripped, the auger will not come on after the initial 5-minute delay. The control
board will not sense the P.O.F. switch in the first 15 minutes and the stove will
eventually shut down. At this time the #3 LED light will start blinking (First
Generation Boards only, Second Generation Boards flash the #2 and #3 light at the
same time). This takes approximately 20 minutes
• Third
let’s look at the
Proof of Fire
switch. This is a normally open switch that
closes on rise at 110 F. The following items would involve a situation where the
stove sensed temperatures in the exhaust system below the normal range.
Remove the
P.O.F
switch from the fan and heat up the contact surface of
the switch with a lighter until you hear a click (approximately 5 seconds).
Test the switch with an Ohm meter for continuity. The switch should be
