OFF CONDITION
When the oven door is closed, the monitor switch contacts COM - NC must be open. When the microwave oven is plugged in a wall outlet (230V (EU) / 230-240V (UK) 50Hz), the noise filter is energized. NOTE: When the oven door is opened, the oven lamp comes on at this time.HIGH COOKING
Enter a desired cooking time by rotating the time/weight knob and start the oven by touching START pad.Power Transformer Operation
The line voltage is supplied to the primary winding of the power transformer. The voltage is converted to about 3.3 volts A.C. output on the filament winding and high voltage of approximately 2000 volts A.C. on the secondary winding. The filament winding voltage (3.3 volts) heats the magnetron filament and the high voltage (2000 volts) is sent to the voltage doubling circuit, where it is doubled to negative voltage of approximately 4000 volts D.C.. The 2450 MHz microwave energy produced in the magnetron generates a wave length of 12.24 cm. This energy is channelled through the waveguide (transport channel) into the oven cavity, where the food is placed to be cooked. When the cooking time is up, a single tone is heard and the relays RY1 + RY3 + RY4 go back to their home position. The circuits to the oven lamp, power transformer, fan motor and turntable motor are cut off.Troubleshooting and error codes
