A garage door built around 1959, which is the center of Richfield's housing stock, was engineered for a different climate expectation than what we design around today. The Twin Cities sit in a cold, moderate climate band, and a door and opener that have been cycling through decades of freeze-thaw swings wear differently than one installed in the last ten years.
Steel contracts in cold, and a torsion spring that's lost its temper over fifty-plus winters doesn't give you the warning a newer spring does. It just lets go. Original hardware on a 1959 house is also more likely to be side-mounted or low-headroom by today's standards, which limits which replacement springs and openers actually fit without modifying the header.
This is the gap between Richfield and the newer sections of the broader service area, where houses built closer to 2002 run newer opener models and standard torsion setups. Here, the hardware is often original or a single prior replacement, and matching it correctly takes knowing what era you're working with before you order a part.
