I think there’s two of those in a row. It’s on the island with the big boiler and Gehn’s study and such, there’s the door into the cavern(?) where you can find the frog trap thing, and you have to close those doors to find the corridor to the spinning orb, then you have to close the door you came in to find the little syncroscope in a side chamber in a wall to stop it.

I don’t remember the second one, but it’s possible I was checking behind every door after that so it would’ve been much easier to notice.
