This isn't a generic opener-wears-out story. It's specific to what got built here and when. Most houses across this service area - roughly 40,189 owner-occupied homes among 50,879 households - went up between 1979 and 2005, with the median sitting around 2002, so a large share of openers in this area are the same builder-installed chain-drive units from that window, now past or approaching the point where boards fail before motors do. Layer Peoria's severe-heat climate band on top of that: a garage here spends months at temperatures that push well past what most opener electronics are rated to handle comfortably, and heat-driven board failure doesn't care how well the door itself was maintained. Median household income in the area sits near $74,764, which is part of why most owners here choose replacement over nursing a dead board along - the math on parts availability and labor usually favors a new head unit once a builder-era opener starts failing. Put those two things together - one construction era, one hard climate - and you get a failure pattern that's common here in a way it wouldn't be in a place with newer housing or a milder summer.
