COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE

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..
To Avoid possible exposure to microwave energy, please follow the instructions below
WARNING:
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.
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.
WARNING AGAINST HIGH VOLTAGE:
WARNING FOR WIRING
2. Drawer latch hook is damaged.
3. The drawer gasket or seal is damaged.
