Most houses in this pocket went up around 1993, sitting inside that 1990-2002 build window, and a lot of them still carry the opener that came with the house. That's a chain-drive unit on a steel rail, original bracket, original logic board - thirty-plus years of use behind it. The stock across the area runs mostly 1980s-90s, which means the failure mode we see most isn't a broken door, it's an opener motor or circuit board that's simply aged out under repeated summer heat cycling. This area sits in a HEAT-severe climate band, and that heat is hard on capacitors, on plastic drive gears, on any sealed board that never gets a break from attic-level temperatures. An opener built for a different climate, or one that's outlived its rated cycle count, doesn't fail dramatically - it just gets slower to respond, then stops responding at all.
