time, the lamp turned on, the fan motor begins to cool the magnetron. The turntable motor set off to drive the food

time, power relay are cut off, the power of the lamp, all the motor and the magnetron are cut off, the food –
heating process ended. During the heating, if the door was opened, the interlock S1, S2 will cut off, S3 will close,
all the motors and the magnetron will also be cut off, the lamp will turn on, the oven stop heating immediately. If
heating need go on, just push down the starting button and closed the door, the oven will continue its working.
When something wrong with the fan motor or the air vent was blocked that breakdown the cooling system, the
magnetron temperature would rise high very quickly. When the temperature reached the working point of the
thermal cutout (S6), S6 will be cut off immediately to cut off the power supply to the magnetron and the
magnetron will stops working right away. The PC board is cut off to prevent the magnetron from being damaged
by overheating. When the thermal cutout is cut off, the magnetron, motors and the lamp would stop working
simultaneously. Moreover, the thermal cutout has the self - resuming character, when the temperature lowered, it
will resume to close condition.
