I'd just not mention it and assume it was fine. After all all the
pcbs have to be the same whether repaired or new, if the circuit was
dangerous then the device would be dangerous no matter what pcb was
in it.

ISTR Geoff, who owns a company which repairs such things, saying that
over a period of time you get to know what things fail on a particular
make, but is not allowed to improve the design by using uprated parts.
It has to be repaired like for like.

Who did he claim wouldn’t allow that ? No one gets to not allow that.

In order to get Gas Council (not sure if its still called this)
approval you have to submit a technical file of the boiler concerned.

Any change would invalidate that certification.

I just don’t believe that Geoff ever had to do anything of the sort.

The UK and EU have rules that replacement parts are of the same
specification for certain items including car parts etc.

That has nothing to do with the replacement of electronic components
on a PCB that have a higher temperature rating than what was originally
there which had a lower temperature rating.

Perhaps you're getting mixed up with other countries that are less
discerning?

You're confusing car parts with electronic components.

There is no legal problem with using a higher rated
starting or running capacitor in an electric motor either.

Or with better rated fans in a computer either.

Or with using higher temperature rated caps
in any switch mode power supply either. Or with
the replacement of caps in electronic devices. Or
with the use of higher current switching relays either.
