Bradenton sits in a mild temperate band, but mild doesn't mean dry - steady coastal humidity year-round is hard on anything with exposed metal gears or circuit boards mounted in an unconditioned garage. That's the main reason opener gears strip early here compared to drier inland climates: constant moisture in the air softens plastic gear teeth and corrodes contact points on older logic boards faster than a straight temperature reading would suggest. Add in the age spread of the housing stock - a lot of homes built in the 1960s and '70s still running original or first-replacement openers - and you get a service area where we see both classic mechanical wear and modern electronic failure in the same week, sometimes on the same street. Salt-tinged air near the water side of the service area speeds up corrosion on any exposed hardware, opener boards included, though we don't have block-by-block humidity data to say exactly how much faster.
