Exhaust Motor

The exhaust motor helps remove heat from all
components. The fan will be ON during cooking. At
the end of speedcooking, the exhaust fan will
continue to run for 1 minute (30 seconds on HIGH
and 30 seconds on LOW), and the display will
read "OVEN IS COOLING." The fan will
automatically shut off when the internal parts of
the oven have cooled.

Upper and Lower Halogen Blowers

The upper and lower halogen blowers only run
during speedcook operations (speedcook recipe
or manual speedcook selections). Both motors
pull in fresh air from outside the unit and direct the
air across the halogen lamps.
Upper Halogen Blower
As you will note from the illustration on the
following page, the upper halogen blower pulls air
in from the upper grille area. The air is then
directed (blown) across the upper halogen lamp
pair and exhausted back into the room through the
lower grille area. The hot air directed across the
upper halogen lamp pair is not controlled or
directed by the exhaust motor.
Lower Halogen Blower
The lower halogen blower draws room air in
through the upper grille area. The air is pulled
down into the lower halogen blower and directed
(blown) across the lower halogen lamp. The air is
then exhausted through the lower grille area.

Magnetron Blower Assembly

During microwave operation, room air is drawn in
through the upper grille area and into the
magnetron blower area. The magnetron fan blows
the cool air through and around the magnetron
tube. The air then passes through the damper
door assembly (damper door is open during
microwave operation) into the oven cavity.
As air enters the oven cavity, pressure builds up
inside, forcing hot air out the top of the oven. The
air passes across the humidity sensor and back
into the room through the lower grille area.
