Teardown & Functional Walkthrough - Samsung Microwave Oven (ME731K)

Watch as I teardown a Samsung Microwave Oven, model ME731K). See how I strip it down to the basics and then walkthrough how the electrical system actually works, optimised for cost and simplicity. I also created a schematic to show how the safety switch configuration works and what goes into generating the high voltages necessary to drive the magnetron. I was able to salvage a nice big high-voltage transformer, switches and motors for other projects. Check out these other animated videos explaining the origin of the magnetron and how it works: Magnetron, How does it work? :    • Magnetron, How does it work?   The curious case of Magnetron's surface charges! :    • The curious case of Magnetron's surface ch...   👉 Don’t forget to like, comment, and subscribe for more teardown videos and electronics salvaging tips!
