text: Here I fix a microwave oven. Never tried it before, but ended up with a successful fix. So anyone with some common sense and a 'go do it' attitude can do the same. The video goes through diagnosing and testing the likely parts that might fail in a microwave oven and then replacing them.
  Conclusione
  A standard microwave oven is actually a simple device comprising of a transformer, diode, capacitor, a fuse and the magnetron valve. All can be tested and replaced to fix a non heating oven. Watch the video.
