COMPONENT TEST
Checking the sensor cooking condition
WARNING: The oven should be fully assembled before following procedure.
(1) The oven should be plugged in at least two minutes before sensor cooking.
(2) Room temperature should not exceed 95°F (35°C).
(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” of the operation manual.
(4) Exhaust vents are provided on the front 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 off by the spray and turn off before food is properly cooked.
(8) If the sensor has not detected the vapor of the food, ERROR will appear, and the oven will shut off.
Water load cooking test
WARNING: The oven should be fully assembled before following procedure.
Make sure the oven has been plugged in at least two 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 d rawer.
(4) Touch the TIMER/Setting pad once, the POWER LEVEL pad twice and the
START pad once. And touch the number pad 1 once and the number pad 4 once. Now, the oven is
in the sensor cooking condition, and "AH20" and "COOK" will appear in the display.
(5) The oven will operate for the first 16 second s, without gene rating microwave energy.
NOTE: ERROR will appear if the door is opened or STOP/CLEAR pad is touched during first stage
of sensor cooking.
(6) After approximately 16 seconds, microwave energy is produced.
If ERROR is displayed or the oven does not turn off, replace the AH sensor, or check the control
unit, refer to explanation below. If the oven stops after 5 minutes and no ERROR code is displayed,
then the AH sensor is normal. Check other parts except the AH sensor.
TESTING METHOD FOR AH SENSOR
To determine if the sensor operation is defective, the simplest method is to replace it with a new
re-placement sensor.
(1) Disconnect the power supply cord, and follow Drawer Disassembly Instructions.
(2) Discharge high voltage capacitor.
(3) Remove the AH sensor.
(4) Install the new AH sensor.
(5) Reconnect all leads removed from components during testing.
(6) Re-install the covers.
(7) Reconnect the power supply cord after the covers are installed.
(8) Reconnect the oven to the power supply and check the sensor cook operation as described above.
