COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE
WARNING AGAINST HIGH VOLTAGE:
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.
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.
WARNING FOR WIRING
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.
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:
THE FOLLOWING ADJUSTMENTS OR COMPONENT REPLACEMENT CAN BE PERFORMED
WITHOUT REMOVING THE OVEN FROM THE WALL
1. | Hood lamps, sockets, grease filter and charcoal filter. | 4. | Hood exhaust louver. |
2. | Base cover and hood lamp glass assembly. | 5. | Control panel assembly or components. |
3. | Turntable motor. |
|

HOOD EXHAUST LOUVER REMOVAL
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.
