OPERATION CHECK

After unpacking this appliance, examine the new oven for evidence of shipping damage. This is most important since a damaged oven may allow the escape of microwave energy. Make sure you remove all packing from the microwave cavity. Check the oven operation when unpacking the unit and any time the oven is not working properly.

Plug the power cord into an earthed electrical socket.
Place the glass tray inside the oven cavity
Place a cup of water (at room temperature) inside the oven, on the glass tray.
Close the door securely.
Set the Timer for 3 to 4 minutes (note : microwave activity starts).
When the cooking time has elapsed, the signal will sound (note: all microwave activity stops).
If the oven is operating normally, the water will behave.

OPERATING PROCEDURE

The microwave oven is designed to be simple and easy to operate. Please follow these instructions carefully.

Place the food in a suitable cooking utensil. Open the microwave oven door and place the utensil in the center of the oven on the glass tray.
Close the oven door.
Turn the TIMER KNOB clockwise to set the cooking time.
When the TIMER reaches OFF, the signal sounds and the oven will automatically shut off.
Open the door and remove the food from the oven.
To stop cooking before the timer reaches OFF, either open the door or simply turn the timer to OFF.

NOTE :

The oven starts as soon as the KNOB is turned. We recommend turning the KNOB past the time you want and then turn back to the desired setting.
The door can be opened during the cooking process by pushing the Door Open Button. The timer will stop and the microwave activity will cease. When the door is closed, cooking will resume until the full cooking time has elapsed. After cooking is finished, the Timer will be at OFF.

CIRCUIT DESCRIPTION

GENERAL DETAILS

When the door is closed, the primary switch is ON, the secondary switch is ON, and the monitor switch opens (contact COM and NO).
The latches are secured by the latch board, the oven light turns on while the oven is operation.

WHEN THE TIMER KNOB IS ROTATED

When the timer knob is rotated, the contacts of timer switch close.
The contact of the secondary switch closes the circuit.
Power input is supplied to the high-voltage transformer through the fuse to the primary timer and secondary switches.
Turntable rotates
The fan motor rotates and cools the magnetron by blowing air (coming from the intake on the baseplate).
The air is also directed into the oven to exhaust the vapor in the oven through the upper plate.
Cooking time starts counting down.
3.2 volts AC is generated from the filament winding of the high voltage transformer. This 3.2 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 DOOR IS OPENED DURING COOKING

Both the primary and timer switches are cut off the primary winding voltage of the high-voltage transformer.
When the door is opened, the secondary switch is opened and when the door is closed, the secondary switch is closed.
The timer, turntable and fan motor stop.
As the door is opened, if the contact of primary 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.
