Why would it need to be replaced now that its working again? ;-)
Except that it had been 5 years since the last maintenance in this place and it was a protection panel for a large synchronous generator in a power plant.
After you make a heroic temporary fix, please, ensure the permanent fix is applied later!
I've known people who would, depending on exactly how bad the failure was, outright refuse to apply temporary fixes precisely because they didn't believe that the business would fix things properly if the issue wasn't forced. And having watched how that particular company handled things, I can't say that they were wrong.
I also think the converse holds (All permanent fixes are temporary).
