TEST PROCEDURES
PROCEDURE
LETTER
COMPONENT TEST
Checking the initial 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
o
F(35
o
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 conventional surface unit. Refer to the "INSTALLATION
INSTRUCTIONS" of the operational manual.
(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 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) If the sensor has not detected the vapor of the food, ERROR will apear and the oven will shut off.
Water load cooking test
Warning: The oven should be fully assembled before following procedure.
Make sure the oven the oven has been plugged in at least two minutes before checking sensor cook
operation . the cabinet should be installed and screws tightened.
(1) The oven should be plugged in at least two minutes before sensor cooking
(2) Fill approximately 200 milliliters (7.2 oz) of tap water in 1000 milliliters measuring cup.
(3) Place the container on the center of tray in the oven cavity.
(4) Close the door.
(5) Touch the Timer/Clock pad once, the Power Level pad twice, the Start pad once and the number pad
once. Now, the oven is in the sensor cooking condition and "TEST", "SENSOR" and "COOK" will appear
in the display.
(6) The oven will operate for the first 16 seconds, without generating microwave energy.
NOTE: ERROR will appear if the door is opened or STOP/CLEAR pad is touched during the first stage
of sensor cooking.
(7) After approximately 16 seconds, microwave energy is produced.
If ERROR is displayed, replace the AH sensor or check the control unit, refer to explaination below. If the
oven stops after 5 minutes and ERROR is displayed, check the parts except for the AH sensor.
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 replacement sensor.
(1) Disconnect the power supply cord, and then remove outer case.
(2) Open the door and block it open.
(3) Discharge high voltage capacitor.
(4)Remove the AH sensor.
(5)Install the new AH sensor.
(6)Reconnect all leads removed from components during testing.
(7)Re-install the outer case (cabinet)
(8) Reconnect the power supply cord after the outer case is installed.
(9)Reconnect the oven to the power supply and check the sensor cook operation as follows:
9-1. Fill approximately 200 milliliters (7.2 oz) of tap water in a 1000 milliliter measuring cup.
9-2. Place the container on the center of tray in the oven cavity.
9-3. Close the door.
9-4. Touch the Timer/Clock pad once, the Power Level pad once and the number pad once.
9-5. The control panel is in automatic sensor operation.
9-6. The display will start to count down the remaining cooking time, and the oven will turn off automatically
after the water is boiling (bubbling).
If new sensor does not operate properly, the problem is with the control unit, and refer to explanation below.
