Most houses across this service area went up between 1969 and 1991, with the typical build year landing around 1972, and the six areas we cover are still dominated by that 1960s-70s stock. That matters for openers because a huge share of these houses have never had the drive unit swapped out - it's the same chain-drive or screw-drive motor that went in when the house was framed, sometimes replaced once in the 90s and never touched since.
Older units run on mechanical limit switches or worn potentiometers instead of the digital travel sensing you'd get today, and those parts drift with age. In a cold moderate climate band, winter temperatures thicken the grease packed into the drive screw or chain housing, which slows the carriage and confuses those old limit settings. The opener either strains to reach full travel and reverses short of closing, or it grinds through the cold snap and burns out the drive gear a season or two early. This isn't a one-house problem - it's the natural result of a service area where the housing stock and the opener stock are both from the same window of time, and both are aging out together.
