To remove the components, procedure as follows.
1. Disconnect the power supply cord.
2. Remove the screws from the rear and along side the edge
of the outer case.
3. Slide the case back about 1 inch (3 cm) to free it from the
oven cavity.
4. Lift entire case from the unit.
5. DISCHARGE TWO HIGH VOLTAGE CAPACITORS
BEFORE TOUCHING ANY OVEN COMPONENTS OR
WIRING.
6. Now, outer case is free.
To remove rear cabinet and power supply cord:
7. Remove the screws holding the rear cabinet to the oven
cavity and blower motor.
8. Remove the one (1) screws holding the switch mounting
angle to the rear cabinet and release the switch mounting
angle from the rear cabinet.
9. Disconnect the power supply cord from the supply harness.
10. Remove the one (1) screws holding the grounding wire of
power supply cord to the oven cavity.
11. Remove the rear cabinet with the power supply cord from
the oven cavity.
12. Loosen the tab of the cord bushing, and remove the power
supply cord with the cord bushing from the rear cabinet.
13. Remove the cord bushing from the power supply cord,
14. Now, the power supply cord and rear cabinet are free.
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:
OUTER CASE, REAR CABINET AND POWER SUPPLY CORD REMOVAL
COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE
To prevent an electric shock, take the following precau-
tions.
1. Before wiring,
1) Disconnect the power supply cord.
2) Open the door and block it open.
3) Discharge the two high voltage capacitors 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, High voltage rectifier assembly and High
voltage wire.
2) Hot parts:
Oven lamp, Magnetron, High voltage transformer, and
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 pull the door release
lever 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 operat-
ing 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.
Oven cavity.
3) Sharp edge:
Bottom plate, Oven cavity, Waveguide flange, Chassis
support and other metallic plate.
4) Movable parts (to prevent a fault)
Blower fan blade, Blower fan motor, Switches, Switch
levers, Antenna motor and Sirrer antennas.
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 PANEL PARTS, DOOR PARTS’, when carrying out any of the
following removal procedures:
