Damper Door Open:
The following illustration shows the position of the
metal damper door in the open position. In this
position, air blowing through and across the
magnetron tube can enter the oven interior. With
the damper door open, the damper door sensing
switch is not depressed.
Damper Door Closed:
The following illustration shows the position of the
metal damper door in the closed position. In this
position, air from the magnetron blower will not
enter the oven interior. With the damper door
closed, the damper door sensing switch is
depressed.
The following damper door positions will occur
with various operations:
•
When the oven is not in use (power applied
to the unit with time-of-day clock showing), the
damper door will always be in the open
position.

•
Speedcooking - At the start of speedcooking
operation, the damper door will close, sealing
off the damper duct from the oven cavity. The
damper door will remain in the closed position
during the entire speedcook operation,
depressing the damper door sensing switch.
•
Microwave oven cooking - At the start of
microwave cooking, the damper door will cycle
one complete revolution (completely close and
then reopen) and stop in the open position
(damper door sensing switch not depressed).
The oven cavity lamps will not illuminate
during microwave operation.
Oven Cavity Lamps
The oven cavity lamps are located at the upper
rear of the oven cavity and illuminate only when
the oven door is opened. During microwave oven
cooking, the oven interior can be illuminated by
pressing the MICROWAVE OVEN LIGHT pad on
the front panel. The lights will come ON and will
remain ON until the end of the cooking cycle. In
the event that it becomes necessary to change the
lamps, it will be necessary to remove the oven
from its installation.
Thermal Fuse
The thermal fuse is mounted to the top of the
damper duct over a small rectangular hole in the
duct. This hole allows the thermal fuse to sense
temperatures inside the duct cavity. The fuse is
secured to the damper duct with a small screw
and retainer. In the event that it becomes
necessary to change this fuse, it will be necessary
to remove the oven from its installation (see page
32).
Air Flow
There are four fan motors in the Advantium design
which provide airflow for proper cooling. During
speedcooking (pre-selected recipe or manual
speedcook), all four fan motors will run during
the entire speedcook operation.
