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 operating the oven.
1. Disconnect the power supply cord.
. Make sure that a definite" click" can be heard when
the microwave oven drawer is unlatched. (Hold the
