I just went out and checked my box. Is separated from furnace box by a fair amount of space. I removed the panel between bottom drawer and power center. Looked at bottom, top and backside with mirror and looked at interior of converter box. No distrotion anywhere. Everything looks fine.
Is it possible your power box are mounted further forward than mine? Do you have 8" dummy between power box and sink cabinet?
I see issues like this is always worth looking at. I started keeping window unlocked when we heard about trimark plunger issue on this board.
