Hi guys,
I am really impressed with the amount of knowledge circling around here
I've just bought a used Panasonic NN-ST479S as my old noname one finally gave up after ten years.
I was told that the fuse keeps blowing on this new one but other than that is fine.
As it came with the lid loose and some screws missing I was a bit worried but it looks OK.
It came with a blown 6A normal ceramic fuse. As I only had 5A, 10A and 13A (UK) plug fuses and a 3.15A glass one I used the latter (no laughing!!!)
After changing it the microwave came to life and boiled a glass of water on MEDIUM heat.
When I choose the Rice/Pasta option it blew the 3.15A fuse (shut up! I've said no laughing!)
After changing it to a new 3.15A fuse it cooked 150g rice in 14mins on MEDIUM heat (no Rice/Pasta option)
So the microwave seems to work OK on Medium heat and obviously I need a higher value fuse for normal operation.
I have two questions:
1) as it came with a 6A fuse (and I really doubt that it's the correct value) I don't know what amperage fuse to use AND should it be glass, ceramic or something special as printed on the PCB: "special fuse"? I guess I need something 15-20A but I could not find a model specific clue.
2) if I put the right fuse in and it still blows it on High heat then what should I check?
Sorry for the long post and thanks for the help
