Two things line up here that you don't get everywhere. First, the age of the housing stock: a door and opener installed when a house went up in the 1960s or 70s has had fifty-plus years to wear out gears, dry out lubrication, and stretch the chain or belt past spec - F1, F2. Second, the mild temperate climate actually hides the problem rather than causing it - F3. In places with hard freezes or heavy storm seasons, an opener failure often gets blamed on weather and people notice it right away. Here, without the ice or the wind events, a slowly failing opener just gets quieter about it. The motor runs a little hotter each cycle, the travel limits drift, and nobody notices until the day it won't open at all. Across a service area with 172,438 owner-occupied houses, a lot of them original mid-century builds, that adds up to a steady stream of openers failing from plain fatigue rather than any single event - F6. It's not a storm problem. It's a time problem.
