Good morning my dear friends and colleagues from the world of electronics, in this momneto I present this case just arrived at my small workshop. It is a brand microwave oven; Daewoo, Model; KOR-6LOB, which stopped working any day, when I check it, the fuse is open, I replaced it with another and it worked normally, but when I opened the oven door it went out, I checked the fuse again and it was open, (F = 15 A, European type), proceeded to check the oven deeply and check all its high voltage components, such as; the magnetron, high-voltage diode, HV capacitor and the HV transformer Everyone measures normally, there are no shorts or leaks in them, so I don't know what else to check, so I ask you for help to discover this electronic puzzle ... thanks. ......

    Comment if the fuse burns when you open the door when it is running or does so without working.
