A torsion spring on a door from the early 1990s is rated for a specific cycle count, and after roughly seven to twelve years of daily use it starts to fatigue even if nothing ever looked wrong. With 7,677 households in Lino Lakes and a median income around $121,800, a lot of these garages see two cars, a mower, and gear going in and out daily, which runs the spring through its rated cycles faster than a seldom-used door would. The cold winters here put extra strain on the coil, too. Steel contracts in low temperatures, and a spring already near the end of its life is more likely to snap on a sub-zero morning than in July. That combination, newer standardized hardware plus heavy daily use plus a real winter, is what actually fails here. It's a different failure pattern than an older Maplewood door with mismatched replacement hardware from years of partial repairs.
