This is a cold-severe climate band, and that matters more for openers than most owners expect. Grease that's fine at 50 degrees stiffens up hard at 10, and a motor that has to push against stiff grease and a cold, swollen door seal works harder every cycle than it was ever designed to. Over a decade or two of winters, that wear adds up faster here than it would in a mild climate.
The other driver is simply age distribution. With housing across this service territory running mostly 1980s-90s stock, a huge share of openers installed as original equipment or as the first replacement are now well past the point where parts are still stocked for them. Drive gears strip, belt systems that were never serviced stretch, and logic boards from the pre-smartphone era just stop communicating with new remotes. None of that is a Germantown-specific defect - it's what happens to any opener this age in a climate that swings this hard, and a big share of the service area's 92,113 owner-occupied houses are sitting right in that window at the same time.
