check fuse F4 and F5 on the control board. A
defective fuse will be darkened or will have a
broken filament. If the fuses are good, the
combustion or exhaust blower is probably
defective. Replace the faulty part.
8. Pressure switch is defective (very rare). 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.
