CIRCUIT DESCRIPTION

GENERAL DETAILS

• The low voltage transformer supplies the necessary voltage to the micom controller when power cord is plugged in.
• When the door is closed, the primary switch is ON, the secondary switch is ON, and the monitor switch opens (contact COM and NO).

WHEN SELECTING COOKING POWER LEVEL AND TIME

• The micom controller memorizes the function you set.
• The time you set appears in the display window.
• Each indicator light turns on to indicate that the stage has been set.

WHEN TOUCHING THE START PAD

• The coil of the relay is energized by the micom controller.
• Power input is supplied to the high voltage transformer through the fuse to the primary switch and relay 2.
• Turntable rotates.
• The fan motor rotates and cools the magnetron by blowing the air (coming from the intake on the base-
• The air is also directed into the oven to exhaust the vapor in the oven through the upper plate.
• Cooking time starts counting down.
• 3.3 volts AC is generated from the filament winding of the high voltage transformer. This 3.3 volts is applied to the magnetron to heat the magnetron filament through two noise-preventing choke coils.
• A high voltage of approximately 2100 volts AC is generated in the secondary of the high voltage transformer which is increased by the action of the high voltage diode and charging of the high voltage capacitor.
• The negative 4,000 Volts DC is applied to the filament of the magnetron.

WHEN THE OVEN IS SET AT ANY LEVEL EXCEPT MAXIMUM.

• The micom controller controls the ON-OFF time of relay 2 by the applied signal to vary the average output power of microwave oven as POWER LEVEL. (refer to page 1-1)
• One complete cycle of relay 2 is 22 seconds.

WHEN THE DOOR IS OPENED DURING COOKING

• Both the primary switch and relay 2 cut off the primary winding voltage of the high voltage transformer.
• ON-OFF of relay 2 is coupled electrically with opening and closing of the secondary switch.
• When the door is opened, the secondary switch is opened and when the door is closed, the secondary switch is closed.
• The cooking time stops counting down.
• Relay stops functioning.
• As the door is opened, if the contact of primary switch and relay2 and/or secondary switch fail to open, the fuse opens due to the large current surge caused by the monitor switch activation, which in turn stops magnetron oscillation.

Power Connection:
Plug the microwave into a grounded outlet with the correct voltage to avoid electrical hazards. Do not use extension cords.

Operating the Microwave:
Follow the instructions in the owner’s manual for setting cooking times, power levels, and any specific functions of the GOLDSTAR MS-194YD model.

Cleaning and Maintenance:
Regularly clean the interior and exterior of the microwave with a mild detergent and soft cloth. Refer to the manual for specific cleaning instructions.
