COMPONENT TEST
(4) Exhaust vents are provided on the back of the unit for proper cooling and air flow in the cavity. To
permit adequate ventilation, be sure to install so as not to block these vents. There should be some
space for air circulation.
(5) Be sure the exterior of the cooking container and the interior of the oven are dry. Wipe off any
moisture with a dry cloth or paper towel.
(6) The Sensor works with food at normal storage temperature.For example. chicken pieces would be
at refrigerator temperature and canned soup at room temperature.
(7) Avoid using aerosol sprays or cleaning solvents near the oven while using Sensor settings. The
sensor will detect the vapor given of by the spray and turn off before food is properly cooked.
Water load cooking test
Make sure the oven has been plugged in at least five minutes before checking sensor cook operation.
The cabinet should be installed and screws tightened.
(1) Fill approximately 200 milliliters (7.2 oz) of tap water in a 1000 milliliter measuring cup.
(2) Place the container on the center of tray in the oven cavity.
(3) Close the door.
(4) Touch INTELLIGENT SENSOR pad and number pads 1 and 0. Now, the oven is in the intelligent
sensor cooking condition and IS-i0 will appear in the display.
(5j Touch Start pad.The oven will operate for the first 16 seconds. without generating microwave en-
ergy.
NOTE: ERROR wili appear if the door is opend or STOP/CLEAR pad is touched during first stage of
sensor cooking.

i6:i After approximately 16 s
econds.
microwave energy is produced, oven should turn off when water
is boiling i bubling).
ii the oven does no: turn off. reoface the AH sensor or check the control unit, refer to TESTING

CHECKING CONTROL UNIT
‘11 Disconnect oven from power supply and remove outer case.
;21 Discharge the high voltage capacitor.
(3; Disconnect the wire leads from the cook relay.
(4; Disconnect the sensor connector.
(5j Then connect the dummy resistor circuit (see fig.) to the sensor connector of control panel.
(6) Reconnect the oven to the power supply and check the sensor cook operation proceed as follows:
6-l. Touch INTELLIGENT SENSOR pad and number 1 and 0 pads.
6-2. Touch Start pad. The control panel is in the sensor cooking operation.
6-3. After approximately 20 seconds. push plunger of select switch.This condition is same as
judgement by AH sensor.
