Most of Chanhassen's housing went up around 1993, which means a lot of garage doors here are original or close to it, pushing thirty years on their rollers and brackets rather than sixty. That's a different failure pattern than the much older stock elsewhere in the service area, where the door itself is more likely to be a later replacement. Here, it's more often the original plastic rollers wearing down, a bracket working loose from repeated expansion and contraction, or a cable fraying until it slips off the drum and lets one side of the door drop out of its track.
Cold is the other driver. The service area sits in a severe cold climate band, and when a track picks up ice or the grease in a roller stiffens overnight, it takes less force than usual to knock the door off alignment. A quick bump from a car bumper or a kid's bike can do it when the hardware is already thirty years tired. We also see it after a spring breaks and the door comes down unevenly, torquing the track enough to pop a roller loose on one side.
