may result in severe, possibly fatal, electric shock.
(Example)
High Voltage Capacitor, Power Transformer, Magnetron, High Voltage Rectifier Assembly, High Voltage Harness
etc..
WARNING:
To Avoid possible exposure to microwave energy, please follow the instructions below
before operating the oven.
WARNING AGAINST HIGH VOLTAGE:
Microwave ovens contain circuitry capable of producing very high voltage and current. Contact with the following parts
COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE
To prevent an electric shock, take the following
precautions:
. Before wiring:
) Disconnect the power supply cord.
2) Open the drawer.
3) Wait 60 seconds, then discharge the high voltage
capacitor.
2. Don’t let the wire leads touch to the following parts:
) 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.
WARNING FOR WIRING
. Disconnect the power supply cord.
2. Make sure that a definite” click” can be heard when
the microwave oven drawer is unlatched. (Hold the
drawer in a closed position with one hand, then pull
the drawer open, this causes the latch leads to rise, it
is then possible to hear a “click’ as the drawer switches
operate.)
3. Visually check the drawer 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:
. Drawer does not close firmly.
2. Drawer latch hook is damaged.
3. The drawer gasket or seal is damaged.
4. The drawer is bent or warped.
5. There are defective parts in the drawer interlock
system.
6. There are de fective parts in the microwave generating
and transmission assembly.
7. There is visible damage to the oven.
Do not operate the oven:
. Without the RF gasket (Magnetron).
2. If the wave guide or oven cavity are not intact.
3. If the drawer is not closed.
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, Switch 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.
