Housing across this service area was mostly built between 1981 and 1996, with a median build year around 1993 - that's the era of chain-drive and early screw-drive openers, many of which are still the original unit installed when the house went up. Those openers are now thirty-plus years old in a lot of cases, and the nylon gears, capacitors, and logic boards inside them have a service life that doesn't stretch that far.
The area's climate band runs moderate on heat, but garages here still sit well above outdoor temperature for most of the year, and an opener's motor and circuit board are mounted right at the ceiling where that heat collects. Circuit boards and start capacitors degrade faster in a garage that runs hot for months at a stretch than they would in a conditioned space, and that's a big part of why we see board failures cluster in houses from this same build era rather than spread evenly across all ages of home.
Across the eight-plus neighborhoods we work in - from the older sections near Mooretown and Sunset Acres to the newer pockets further out - the pattern holds: same decade of construction, same generation of hardware, same failure points showing up on repeat.
