pipe are blocked with ash or
foreign material.
The firebox is not properly
sealed.
Vent pipe is incorrectly
installed.
Airflow switch wire
connections are bad.
Combustion blower failure.
Control board not sending
power to combustion blower.
Control board not sending

TROUBLE SHOOTING GUIDE
Possible Remedies: (Unplug stove first when possible)
Unhook air hose from the air switch and blow through it. If air flows freely, the hose
and tube are fine. If air will not flow throw the hose, use a wire coat hanger to clear
the blockage.
Follow all cleaning procedures in the maintenance section of the owner's manual.
Make sure the door is closed and that the gasket is in good shape.
Check to make sure vent pipe installation meets criteria in owner's manual.
Check the connectors that attach the gray wires to the air switch.
With the stove on, check to see if the combustion blower is running. If it is not,
you will need to check for power going to the combustion blower. It should be a full
current. If there is power, the blower is bad. If there is not, see #7.
If there is no current going to the combustion blower, check all wire connections. If
all wires are properly connected, you have a bad control board.
There should be a 5-volt current (approximately) going to the air switch after the
stove has been on for 30 seconds.
To test the air switch, you will need to disconnect the air hose from the body of
the stove. With the other end still attached to the air switch, very gently suck on
the loose end of the hose (you may want to remove the hose entirely off the stove
and the air switch first and make sure it is clear). If you hear a click, the air switch
is working. BE CAREFUL TOO MUCH VACUUM CAN DAMAGE THE AIR SWITCH.
