Goodyear's housing stock is concentrated in one window - most of it went up between 2001 and 2007, and that same era of construction repeats across the main pockets of the city. That matters for openers because it means a huge share of the garages here got the same builder-installed unit, installed to the same spec, in the same few years. They're all aging out at roughly the same time. Layer on the climate - this is a severe-heat band, not a mild one - and you get a motor and circuit board that spend a good chunk of every year sitting in a garage that regularly tops 110 degrees. Heat is hard on plastic gears, hard on capacitors, hard on the grease inside the motor housing. An opener rated for general use doesn't get a pass on that just because it's indoors. So the failure pattern we see isn't random: it's 2000s-era builder-grade openers reaching the end of a heat-shortened lifespan, at roughly the same time, across a service area where most houses were built in the same seven-year stretch.
