Pennsylvania winters here sit in a cold-severe climate band, and that matters more for openers than people expect. Cold tightens grease in old gear-and-sprocket units, and a motor built decades ago wasn't engineered around today's insulated door weight or today's duty cycle. A lot of Colonial Park households run two cars in and out daily, sometimes more, and an opener from the 1960s or 70s wiring era just wasn't built for that load over fifty-plus winters. The failure pattern we see most is the drive gear stripping in deep cold, right when the motor works hardest to pull a heavier, colder door off a frozen seal. That's not a Colonial Park-specific defect, it's physics meeting old hardware, but the hardware age here is what sets the clock on when it happens.
