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..

WARNING:

Avoid possible exposure to microwave energy. Please follow the instructions below before

operating the oven.

WARNING AGAINST HIGH VOLTAGE:

COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE

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 following parts;

1) High voltage parts:

Magnetron, Power transformer, High voltage

capacitor and High voltage rectifier assembly.

2) Hot parts:

Oven lamp, Magnetron, Power transformer and Oven

cavity.

WARNING FOR WIRING

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:

Base cover, Base plate R, 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 and Mounting lever.

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, RIGHT PANEL PARTS, DOOR PARTS’, when carrying out any of the

following removal procedures:

THE FOLLOWING ADJUSTMENTS OR COMPONENT REPLACEMENT CAN BE PERFORMED

WITHOUT REMOVING THE OVEN FROM THE WALL

1. Hood lamps, sockets.

2. Base cover and hood lamp glass assembly.

3. Turntable motor.

4. Right panel parts

REMOVAL OF OVEN FROM WALL (Two persons recommended to remove the oven)

1. Disconnect the power supply cord, and uncoil the power

supply cord.

2. To discharge the high voltage capacitor, wait for 60

seconds.

3. Remove the turntable tray and support from the oven cavity.

4. Remove the two (2) screws holding the oven (outer case
