The climate here is mild temperate - no deep freezes, no extreme humidity swings that crack wood doors the way you'd see further north. That takes a few failure modes off the table. What's left is mostly mechanical fatigue: a spring that's done its 10,000 cycles, a cable that's frayed from years of running over a rusted-out pulley, or a center bearing plate that's worked loose from the header. Steel doors on 1990s-era tracks also tend to show bent track more than broken panels, because the galvanized steel of that era dents and bows before it fails outright. We also see a fair number of opener failures tied to the logic boards of that generation - they weren't built to run twenty-plus years, and a lot of them are now on their second or third remote before the board itself finally quits.
