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.
