Right fuse for NN-ST479S? Value and material?

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

Hi,

Need to check with a UK parts store....I couldn't find a parts breakdown for this UK style microwave.

Thanks Rick and Jeff,

I could not find it myself either hence I came here.
I think I can play safe with Rick's suggestion and try a 20A even though this side of the pond everything is twice as (good) high - even the current

I will buy a 20A today and report back.

Thanks again

The fuse holder area often has a small tag/sticker that may have the fuse size printed on it.

That was the first thing I checked actually - the words "special fuse" are printed on the PCB only, no values. Life would just be too easy probably...

no values. Life would just be too easy probably...

Of course

Solved

Hi guys,

I was quite busy last week but by Friday I have managed to buy a 10A time delay fuse (that was the highest Amp available in 20mm size) and everything was working just fine even the High and Turbo mode as well. This Wednesday I received the 20A fuse from eBay and replaced the 10A one.

So all in all everything looks good and I have a brand new £160 microwave for £9 (plus £11 postage) plus a price of a fuse

Thanks for the help!
