I take your point, the issue is that some parts of a boiler are deemed
safety critical. A whole PCB may be such an item where the manufacturer
has no intention of it being repairable.

It's very odd. As you say most makers only supply new ones. No need to go
to the bother of fixing them if they can con you into paying for new.

My Viessmann PCB hasa several PCB fuses - the soldered in sort so not user
replaceable, unlike the main one. Yet they don't offer a repair service
for it. So why make it more expensive to manufacture than actually needed
- if it is a throw away part when faulty?

I entirely agree with your sentiment, hence why I wholeheartedly support
the likes of Geoff.

Not so long ago, circuit diagrams were published for TVs and video
recorders and the like. If we truly want to stop the unnecessary wastage
of raw materials through premature scrapping old items, perhaps one
thing a company who claims to be green could do, is to publish their
diagrams. Those diagrams sometimes highlighted safety critical items to
help select alternative components.

The issue is that it is usually cheaper to replace with new than to
fault find and repair.
