With most Oak Grove homes dating to around 1984, the failure pattern is different from what shows up in the older 1960s-70s stock elsewhere in the service area. Doors from this era usually came with galvanized torsion springs and steel tracks that have now put in three to four decades of cycles - springs don't fail from one bad day, they fail from fatigue, and a 40-year-old spring is well past its rated cycle count even if it looks fine.
The cold moderate climate here means metal contracts hard on the coldest nights, and a spring already near the end of its life is more likely to snap on that kind of night than on a mild one. Panels from this build era also tend to be single-layer steel without much insulation, so they dent and rust at the bottom corners faster than a home would expect. None of that means the door is unsafe to use daily - it means when it's time to replace, it's usually the whole spring-and-track system going at once, not one part.
