Transformer replacement for a dead coffee machine

[double_DD]

Hi guys,

I have a dead coffee machine, and it seems that the culprit (no 1, at least) is a dead trafo - primary coil seems to be blown open (type shown on the picture below).

Now, I'm unable to find direct replacement anywhere on ebay or aliexpress, and all similar that I' was able to find are rated too low (<1A).

If someone knows a shop to buy replacement (EU/CH), that would of course be my 1st option.
My other ideas:
- to buy 220/20Vac trafo with 30VA, and to "manually" create secondary 12V output just via resistor
- to buy 220/2x12Vac trafo with at least 30VA, use single output and serial connection of both + resistor to reduce to 20V from 24V (is this even possible?!)

Any other, better or simpler ideas? Or if my ideas are stupid, don't hesitate to explain why.

Thanks in advance!

UPDATE:
Well, never mind me, when you destroy insulation on primary eventually you reach thermal fuse that's blown, probably the only issue with it. I'll just replace that and hope everything else is working.

Thread can be closed and deleted.

we dont delete stuff
anyway, you may be back if it blows another fuse.

I've tested it already with the power supply, both 20V and 12V circuits seem to be OK (or at least don't have shorts) 😀
So I hope not to have to continue the thread 😁

What confused me was the size of the thermal fuse, I've never seen ones so small, used to bigger ones that cannot be hidden under insulation. 😐

Or you put a dual voltage smps with 24v and 12v DC. Take that transformer out, fork the rectifier diodes and let her have it!

Yeah, that was one of my first ideas aswell. But I've noticed that transformer outputs do not go directly to rectifiers, and I was to lazy to check what's really going on.
Anyway, now it's fixed and reassembled.

At least you were able to fix it. Doesn’t matter which way, as long as it works and better even if it’s a cheap repair.

Fully agreed!
