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.
Possibles remedies (Unplug stove first
