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 grounded properly before beginning repair work.

2) Warning about the electric charge in the high voltage capacitor.

For about 30 seconds after the operation stopped and electric charge remains in the high voltage capacitor.

W hen replacing or checking parts, short between oven chassis

and the negative high terminal of the high voltage capacitor, by using a properly insulated screwdriver to discharge.

4. W hen the 12A 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 rem ove their w atches w henever working close to or replacing the m agnetron.

CAUTION

W hen servicing the appliance, need a care of touching or replacing high potential parts because of electrical

shock or exposing microvave. These parts are as follows - HV Transformer, Magnetron, HV Capacitor, HV Diode, HV Fuse.
