My Viessmann PCB hasa several PCB fuses - the soldered in sort so not

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.


As usual, you miss the point entirely. Why fit fuses - where there's no
fire risk - if there is no method given for replacing them in service?

Why, so that a potential fault doesn't cause a fire. Making the fuse a
serviceable item, doesn't remove the original fault.

A good example is here;
