COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE
WARNING AGAINST HIGH VOLTAGE:
Microwave ovens contain circuitry capable of producing very high voltage and current. Contact with the following parts may result in severe, possibly fatal, electric shock.
(Example)
High Voltage Capacitor, Power Transformer, Magnetron, High Voltage Rectifier Assembly, High Voltage Harness etc..
WARNING: To Avoid possible exposure to microwave energy, please follow the instructions below before operating the oven.
1.Disconnect the power supply cord.
2.Make sure that a definite” click” can be heard when the microwave oven drawer is unlatched. (Hold the drawer in a closed position with one hand, then pull the drawer open, this causes the latch leads to rise, it is then possible to hear a “click’ as the drawer switches operate.)
3.Visually check the drawer and cavity face plate for damage (dents, cracks, signs of arcing etc.).
Carry out any remedial work that is necessary before operating the oven.
Do not operate the oven if any of the following conditions exist:
1.Drawer does not close firmly.
2.Drawer latch hook is damaged.
3.The drawer gasket or seal is damaged.
4.The drawer is bent or warped.
5.There are defective parts in the drawer interlock system.
6.There are defective parts in the microwave generating 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 drawer is not closed.
WARNING FOR WIRING
To prevent an electric shock, take the following pre- cautions:
1.Before wiring:
1)Disconnect the power supply cord.
2)Open the drawer.
3)Wait 60 seconds, then discharge the high voltage capacitor.
2.Don’t let the wire leads touch to the following parts:
1)High voltage parts:
Magnetron, High voltage transformer, High voltage capacitor and High voltage rectifier assembly.
2)Hot parts:
Oven lamp, Magnetron, High voltage transformer and Oven cavity.
