Microwave ovens contain circuitry capable of producing very high voltage and current, contact with following parts may
result in severe, possibly fatal, electric shock.
(Example)
High Voltage Capacitor, Power Transformer, Magnetron, High Voltage Rectifier Assembly,  High Voltage Harness etc..

To prevent an electric shock, take the following pre-
cautions.
1. Before wiring,

1) Disconnect the power supply cord.
2) Open the door block it open.
3) Discharge the high voltage capacitor and wait for 60

seconds.

2. Don’t let the wire leads touch to the followiong parts;

1) High voltage parts:

Magnetron, High voltage transformer, High voltage
capacitor and High voltage rectifier assembly.

2) Hot parts:

Oven lamp, Magnetron, High voltage transformer
and Oven cavity.

1. Disconnect the power supply cord.
2. Make sure that a definite” click” can be heard when the

microwave oven door is unlatched. (Hold the door in a
closed position with one hand, then push the door open
button with the other, this causes the latch leads to rise,
it is then possible to hear a “click’ as the door switches
operate.)

3. Visually check the door and cavity face plate for damage

(dents, cracks, signs of arcing etc.).

Carry out any remedial work that is necessary before
operating the oven.
Do not operate the oven if any of the following conditions
exist;

1. Door does not close firmly.
2. Door hinge, support or latch hook is damaged.
3. The door gasket or seal is damaged.
4. The door is bent or warped.
5. There are defective parts in the door interlock system.
6. There are defective  parts in the microwave generating

and transmission assembly.

7. There is visible damage to the oven.

Do not operate the oven:
1. Without the RF gasket (Magnetron).
2. If the wave guide or oven cavity are not intact.
3. If the door is not closed.
4. If the outer case (cabinet) is not fitted.

3) Sharp edge:

Bottom plate, Oven cavity, Waveguide flange,
Chassis support and other metallic plate.

4) Movable parts (to prevent a fault)

Fan blade, Fan motor, Switch, Open lever, Open
button.

3. Do not catch the wire leads in the outer case cabinet.
4. Insert the positive lock connector until its pin is locked

and make sure that the wire leads do not  come off even
if the wire leads are pulled.

5. To prevent an error function, connect the wire leads

correctly, referring to the Pictorial Diagram.

Please refer to ‘OVEN PARTS, CABINET PARTS, CONTROL PANAL PARTS, DOOR PARTS’, when carrying out any of
the following removal procedures:

1. Hood lamps, sockets, grease filter and charcoal filter.
2. Base cover and hood lamp glass assembly.
3. Turntable motor.

4. Hood exhaust louver.
5. Control panel assembly or components.

1. Disconnect the power supply cord.
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for 60

seconds.

4. Remove the three (3) screws holding the hood exhaust

louver to the oven cavity front face plate.
