1-5. The 240 vol?s A.C. to the damper motor is stopped and
the motor turns off.
2. When oven is microwave cooking:
Damper is in the open position
3. When oven is convection cooking:
3-1 Damper motor is energized by touching the convection
temperature and START pads.
3-2. When damper is in the closed position (damper switch
is OFF), its signal is sensed by the control unit, and
shut-off relay (RY4) is de-energized.
3-3. The damper is held in the closed position during the
convection cooking operation
3-4. At the end of the convection cooking, shut-off relay
(RY4) is energized, and the damper is returned to the
open position.
NOTE: If the damper door is not in the proper position, closed
durining convection or open durning microwave, the
control unit will stop oven operation after 1 minute.

WEIGHT SENSOR ASSEMBLY
1. When the food is placed on the turntable, the gap
between the eictrodes increases in direct propor-
tional to the weight of food. The elctrodes have the
function of a capacitor.
2. The frequency of the oscilator changes according to
the capacitance of the weight sensor.
3. The micro-computer measures the weight of food by
detecting the change in the oscilating frequency.
