I'm not sure HOW static electricity could build up, but, that's the only
thing, at the moment, that makes sense to me.

If it only happens when you turn it on, it wouldn't be static build up.
That would have dissipated while it was off.

I'm wondering about some kind of misalignment or wearing out in a
two-pole switch. If one side of the 240 is energized ten milliseconds
before the other, AND that side is shorted to the shell, AND the shell
is not grounded but the vent hose _is_, then this could happen.

And that would be dangerous, obviously. Call a pro. Happy Halloween.
