2 , the door interlock switch from the first door interlock switch S1, the second door interlock switches S2, S3 door monitoring switch components. When the door is closed , the door hook operation , S1, S2 closed , S3 open, and a microwave in the standby state. When the door opens , S1, S2 OFF , S3 closed, the microwave oven does not work . If you encounter switch failure or human causes , because S3 is on, the 220V power supply short circuit , FU1 fuse , play a protective role.AF5service manual download site

3, Timer linked by a synchronous motor M1 and the timing of the switch S4 composed mainly used to control the input power transformer energization , which regulate the work of the magnetron / stop the proportion of time, thereby regulating the microwave output power. Microwave 6 files firepower : High Fire - 100% power output in high fire - 85% power output k fire - 66% power output ; low fire - 40% power output ; thaw - 37% power output ; low
