PROCEDURE
LETTER
COMPONENT
TEST
AH SENSOR
Checking
the initial
sensor
cooking
condition
(1) The oven should
be plugged
in at least five minutes before sensor cooking.
(2) Room temperature
should
not exceed 95 "F.
(3) The unit should
not be installed
in any area where heat and steam are generated.
The unit
should
not be installed,
for example,
next to a conventional
surface
unit.
Refer to the
"INSTALLATION
Instructions".
(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.
(8) After 30 minutes
if the sensor has not detected the vapor of the food, ERROR will appear
and the oven will shut off.
Water
load cooking
test
Make sure the oven has been plugged
in at least five minutes before checking
sensor cook op-
eration. 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
SENSOR COOK pad and number
pad 2. Now, the oven is in the sensor cooking
condition
and SC-2i indicator
will appear in the display.
(5) Touch Start pad.The oven will operate for the first 16 seconds, without
generating
micro-
wave energy.
When the AH sensor is defective
(open or short),
ERROR will appear in the display after 16
seconds cleaning
time.
If ERROR appears check sensor wire connections
and/or
AH sensor.
NOTE:
ERROR will appear if the door is open or STOP/CLEAR
pad is touched
during
first
stage of sensor cooking.
(6) After approximately
16 seconds, microwave
energy is produced,
oven should turn off when
water is boiling
(bubbling).
If the oven does not turn off, replace the AH sensor or check the control
unit, refer to expla-
nation below:

TESTING
METHOD
FOR AH SENSOR
AND'/OR
CONTROL
UNIT
To determine
if the sensor is defective,
the simplest
method
is to replace
it with
a new re-
placement
sensor.
(1) Disconnect
oven from power supply
and remove outer case.
(2) Discharge
the high voltage capacitor.
(3) Remove the AH sensor.
(4) Install the new AH sensor.
(5) Re-install
