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 #8.
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.
