WARNING TO  SERVICE  PERSONNEL

Microwave ovens contain circuitry capable of pro-
ducing very high voltage and current, contact with
following parts   may result in a severe, possibly
fatal, electrical shock.

(Example)

High Voltage Capacitor, High Voltage Power Trans-
former, Magnetron, High Voltage Rectifier Assem-
bly,  High Voltage Harness etc..

Read the Service Manual carefully and follow all
instructions.

Before Servicing

1. Disconnect the power supply cord

,  and then

remove outer case.

2. Open the door and block it open.
3. Discharge high voltage capacitor.

WARNING:RISK OF ELECTRIC SHOCK.

DISCHARGE THE HIGH-VOLTAGE
CAPACITOR BEFORE SERVICING.

The high-voltage capacitor remains charged about 60
seconds after the oven has been switched off. Wait for 60
seconds and then short-circuit the connection of the high-
voltage capacitor (that is the connecting lead of the high-
voltage rectifier) against the chassis with the use of an
insulated screwdriver.

Whenever troubleshooting is performed the power supply
must be disconnected. It may, in  some cases, be necessary
to connect the power supply after the outer case has been
removed, in this event:
1. Disconnect the power supply cord, and then remove

outer case.

2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Disconnect the leads to the primary of the power

transformer.

5. Ensure that the leads remain isolated from other

components and oven chassis by using insulation tape.

6. After that procedure, reconnect the power supply cord.

When the testing is completed,
1. Disconnect the power supply cord, and then remove

outer case.

2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Reconnect the leads to the primary of the power

transformer.

5. Reinstall the outer case (cabinet).
6. Reconnect the power supply cord after the outer case is

installed.

7. Run the oven and check all functions.

After repairing

1. Reconnect all leads removed from components during

testing.

2. Reinstall the outer case (cabinet).
3. Reconnect the power supply cord after the outer case is

installed.

4. Run the oven and check all functions.

Microwave ovens should not be operated empty. To test for
the presence of microwave energy within a cavity, place a
cup of cold water on the oven turntable, close the door and
set  the power to HIGH and set the microwave timer for two
(2) minutes. When the two minutes has elapsed (timer at
zero) carefully check that the water is now hot. If the water
remains cold carry out Before Servicing procedure and re-
examine the connections to the component being tested.

When all service work is completed and the oven is fully
assembled, the microwave power output should be checked
and a microwave leakage test should be  carried out.

Don't Touch !
