COMPONENT REPLACEMENT/ADJUSTMENT
PROCEDURE
icrowave ovens contain circuitry capable of producing very high voltage and current, contact with the following
arts may result in severe, possibly fatal, electric shock.
(ample
gh Voltage Capacitor, Power Transformer, Magnetron, High Voltage Rectifier Assembly, High Voltage Harness
c..
Avoid possible exposure to microwave energy.
Please follow the
instructions below before operating the oven.
Disconnect the power supply cord.
Visually check the door and cavity face plate for
damage (dents, cracks, signs of arcing etc.).
arty out any remedial work that is necessary before
operating the oven.
o not operate the oven if any of the following condi-
Ins exist;
Door does not close firmly.
Door hinge, support or latch hook is damaged.
The door gasket or seal is damaged.
The door is bent or warped.
5. There are defective parts in the door interlock sys-
tern.
6. There are defective parts in the microwave gener-
ating 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 prevent electric shock, take the following pre-
3utions.
Before wiring.
;) Disconnect the power supply cord.
2) Open the door and block it open.
3) Discharge the high voltage capacitor and wait for
60 seconds.
!. Don't let the wire leads touch the following parts;
1) High voltage parts:
Magnetron, High voltage Transformer, High volt-
age capacitor and High voltage rectifier assembly.
2) Hot parts:
Oven lamp, Magnetron, High voltage Transform-
er 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 , Switch lever, and
Open button.
3. Do not catch the wire leads in the outer case cabi-
net.
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 Wiring Diagram.
