I don't know why the designers did not consider the connection point at the roof, Isn't there a disconnect .. It obviously didn't get inspected because no inspector would allow a splice point that was not readily accessible.

Chances are a poor connection finally arced apart from the excessive load upon a poor connection, finally oxidizing to the point of an open.

I'd sell them on keeping all the fan circuits up on the roof using strut and either simple EMT or better yet rigid..

Careful on that poor design, it sounds dangerous either way.

Maybe get a crane, pull the unit, get the slice point on the roof and start from there.

Good luck, it sounds like a major hassle. But a nice challenge ..
