With a median year built of 1964, a lot of Elmhurst's garages are on their second or third spring already, sometimes replaced by whoever owned the house before with parts that don't quite match the door weight. That mismatch is a common root cause we find on emergency calls - a spring rated for a lighter door installed on a heavier one, working fine for a while and then failing without warning.
The area sits in a cold moderate climate band, and steel spring wire fatigues faster through repeated cold-to-warm cycling than in a climate that stays steady. It's not the headline reason most doors fail here, but it shortens the life of hardware that's already past its expected cycle count on a house this age. Combine original 1960s-era hardware with 60 years of temperature swings and the failures cluster where you'd expect: springs and cables, not panels.
