Mechanical microwave oven: Turn the power regulator to the highest power position, and the timer pointer is rotated to the position of about 10 minutes. After the microwave oven is started, about 5 minutes, open the furnace door and touch the water cup. It should be hot or boiling (depending on the stove). The amount of power and the amount of water may vary). Then, turn the power regulator to the middle power, half power, "thaw" and other gears, each working for 1-2 minutes, you should feel the microwave oven in these gears. "Open and stop" phenomenon. In view of the difference in the position of the furnace lamp in the microwave oven, during the operation of the microwave oven, when and when it is turned off may be different in various microwave ovens: in some work, the light is on, after the door is turned on, the light is off; and some are reversed. The user has no way of knowing the connection of the lamp, but by the operation in the selection, it should be considered normal as long as the lamp is on and off, which is regular rather than random. The glass turntable in the cavity is rotated when the microwave oven is working. There should be no stop and stop when rotating, and the sound should not be too large, and there should be no abnormal noise. At present, in order to increase the life of the magnetron, the fan motor speed is increased, and the fan noise is slightly increased, but both are controlled within a reasonable degree. Through this measure, the life of the heart of the microwave oven - the magnetron is greatly improved. The direction of rotation of the plate after each start of the microwave oven is arbitrary. This is determined by the characteristics of the turntable motor and is normal.
