Had a torsion spring break on my overhead door. It turns out they have a cycle life, and apparently mine was exceeded. I suppose I could use home automation to keep track of the cycle count when I install a new one. On the other hand, there's something to be said for simplicity, and just having a mechanical counter that increments by one after each open-close cycle. Either way, next time I'll know to replace before the failure occurs.
