DISASSEMBLY AND ASSEMBLY

Cautions to be observed when troubleshooting.

Unlike many other appliances, the microwave oven is high-voltage, high-current equipment. 
It is completely safe 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 grounding.

Do not operate on a two-wire extension cord.
The microwave oven is designed to be used while earthed.
It is imperative, therefore, to make sure it is earthed 
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. 
When 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. When the 10A 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, HV fuse.
