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?

Basically its much cheaper for them to make a new pcb than it is to
employ skilled people to diagnose and repair pcbs that have failed.

That's the way the entire industry that uses pcbs has operated for decades
now.

Corse that doesn’t mean that skilled individuals like Geoff can't make a
very decent business repairing pcbs, but the boiler manufacturers can't.
