6. DISASSEMBLY AND ASSEMBLY

- Cautions to be observed when trouble shooting.

Unlike many other appliances, the microwave oven is high-voltage, high-current equipment.

It is completely safety during normal operation. However, carelessness in servicing the oven

can result in an electric shock or possible danger from a short circuit.

You are asked to observe the following precautions carefully.

1. Always remove the power plug from the outlet before servicing.

2. Use an insulated screwdriver and ware rubber gloves when servicing the high voltage side.

3. Discharge the high voltage capacitor before touching any oven components or wiring.

1) Check the earthed.

Do not operate on a two-wire extension cord.

The microwave oven is designed to be used

with earthed. It is imperative, therefore, to

makes sure it is earthed properly before beg-

inning repair work.

2) Warning about the electric charge in the high

voltage capacitor.

For about 30 seconds after the operation sto-

pped and electric charge remains in the high

voltage capacitor. When replacing or checking

parts, short between oven chassis and the

negative high terminal of the high voltage

capacitor, by using a properly insulated screw-

driver to discharge.

4. When the 15A fuse is blown out due to the

operation of the monitor switch; replace primary

interlock switch, secondary interlock switch and

interlock monitor switch.

5. After repair or replacement of parts, make sure

that the screws are properly tightened, and all

electrical connections are tightened.

6. Do not operate without cabinet.

CAUTION : Service personnel should remove their watches whenever working close to

or replacing the magnetron.

WARNING : When servicing the appliance, need a care of touching or replacing high

potential parts because of electrical shock or exposing microwave. These parts are

as follows - HV Transformer, Magnetron, HV Capacitor, HV Diode.
