8. Pressure switch is defective

Even though this situation is highly unlikely, it's
possible the pressure switch is defective. To test the
airflow pressure switch, you need to disconnect the air
hose from the blower casing. With the other end still
attached to the switch, very gently suck on the loose
end of the hose (you may want to completely
disconnect the hose from the stove and the switch first
and make sure it is clear). If you hear a « click », the
switch is working. Be careful: too much suction can
damage the switch.
