It's probably needed it for several years, a few more weeks won't hurt anything.

The capacitors are always bad, these are ~25 year old machines, they were never intended to last that long. It's one of those things I don't even bother testing, I just replace the capacitors whenever I work on one of them. Sort of like I'd replace the belts, hoses, brakes and fluids on an old car that had been sitting around for years before driving it around much.
