Just be careful not to poke too close to the bungholes, lest you create a leak...

All the RIFA or line filter gave out magic smoke when wife watch me playing the “toys”  :palm:

Yes, I know that there is high possibility for those RIFA giving up when plug into 220V supply after sitting most of their life in 115V environment, but the timing can’t be so coincident.  :-//

Worst case is those capacitor slowly leaking through earth which trip the GFI after some time.

Note: Not sure why HP 8950L series SA power supply use X instead of Y

Refrigerator:
RIFA caps failing wouldn't be that big of an issue if they didn't fail in the exactly opposite way a class X or Y capacitors are designed to fail.

Are you sure it's X? This crap comes in both X and Y flavor. https://content.kemet.com/datasheets/KEM_F3016_PME271Y_Y2_250.pdf

You are right, it was marked as 250-Y2, 300-X1. It measured 3x MOhm when I applied 250 V across it. The good one measure few hundred MOhm.
