Re: Matsui 175S microwave fuse replacement



Thanks.

Finally got round to trying this, tried it with the replacement fuse connected to both connectors on the right terminal in turn but no difference whatsoever to the outcome unfortunately. The microwave powers on and the turntable turns as it should do, but no heating takes place. Am assuming at this point that it must be either a failed magnetron, diode or cap, but not sure I have the troubleshooting skills to get much further with this....

Re: Matsui 175S microwave fuse replacement



OK I've attached a picture to show more, but just to spell it out the connections on the cap are as follows (when I say "left" I mean my left as I look at it):

Left hand terminal of cap:
- black lead to diode, red lead to magnetron (these two share the same connector)
- white lead to transformer.

Right hand terminal of cap:
- red-with-black-stripes lead to fuse holder.

But as I said originally my query was only about the fuse holder, which I unplugged...

The diode is connected to the cap itself, not the transformer. I've added another photo that shows it better. I'm not messing with what's already there; I've no reason to believe that there were any existing wrong connections when I got it. The red / black wire is the replacement fuse holder that I was asking about originally; although I think I've now concluded that as long as it goes on the right side of the cap it doesn't matter much how you connect it.


It's a nineties microwave; that's what 30 years of...

Re: Matsui 175S microwave fuse replacement


Thanks Your response confused me a bit at first but I went back and looked at the capacitor again and I think I was misunderstanding what I was looking at before. Each side of the capacitor has two "prongs" on it - for want of a better word - that can hold separate connectors - but it's just the same terminal so it doesn't really matter which of the two available prongs you attach the fuse holder to, am I making sense? I've attached another photo from a different angle as I realise the one before doesn't show what I'm...

Hi,

I recently picked up a used Matsui 175S microwave that was powering up (starts, turntable rotates) but not heating. From looking online the most likely culprit was the fuse, but unfortunately in this one the fuse had heated up and fused with the (badly designed) fuse holder and couldn't be removed. I guess this might indicate further issues beyond the fuse itself but at this stage I just want to replace the fuse and see how I go from there.

Anyway since I couldn't get out the fuse itself the easiest fix was to replace the fuse holder assembly that runs between the...
