Component Replacement And Adjustment Procedure; Warning Against High Voltage; Warning For Wiring - Sharp KB-6524PS Service Manual

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..
WARNING: To Avoid possible exposure to microwave energy, please follow the instructions below
before servicing the oven.
. 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:
To prevent an electric shock, take the following precautions:
. Before wiring:
) 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:
) 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
