I take your point, the issue is that some parts of a boiler are deemed

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.

For cheap goods that's true.

It isnt just cheap goods, its true of almost all pcbs now,
even in computers and has been for decades now.

For goods like boilers, electronic repairs make a lot more sense.

Like hell it does for the manufacturer. It is MUCH cheaper to
just churn out a new one using the manufacturing process
that is used to make them in the first place than to employ
skilled people to diagnose and repair pcbs that have failed.

The computer industry worked that out decades ago now.

Same with all the domestic appliances too.
