1960 build year spring failure
Both point to a torsion spring that's lost tension, and in this town that's not a surprise. The median house here was built around 1960, which puts Western Springs squarely inside the 1938-to-1994 window that covers this whole service area, and squarely in the era when builders hung steel sectional doors on side-mounted torsion springs rated for maybe 10,000 cycles.
