() Disconnect the power supply cord, and then remove outer case.

(2) Open the door and block it open.

(3) Discharge high voltage capacitor.

(4) Disconnect the sensor connector that is mounted to control panel.

(5) Then connect the dummy resistor circuit (see fig.) to the sensor connector of control panel.

(6) Disconnect the leads to the primary of the power transformer.

(7) Ensure that these leads remain isolated from other components and oven chassis by using insulation

tape.

(8) After that procedure, re-connect the supply.

(9) Check the sensor cook operation proceed as follows:

9-. Touch Sensor reheat pad once and touch the Start pad.

9-2. The control panel is in the sensor cooking operation.

9-3. After approximately 32 seconds, push plunger of select switch for more than 3 seconds. This

condition is same as judgement by AH sensor.

9-4. After approximately 3 seconds, the display shows " X X . X X " which is the remaining cooking

time, and the display count down.

If the above is not the case, the control unit is probably defective.

If the above is proper, the AH sensor is probably defective.

(0) Disconnect the power supply cord, and then remove outer case.

() Open the door and block it open.

(2) Discharge high voltage capacitor.

(3) Disconnect the dummy resistor circuit from the sensor connector of control panel.

(4) Carry out necessary repair.

(5) Reconnect all leads removed from components during testing and repairing.

(6) Re-install the outer case (cabinet).

(7) Reconnect the power supply cord after the outer case installed. Run the oven and check all function.

(8) Carry out "Water load cooking test" again and ensure that the oven works properly.
