Houses in this area mostly date to the 1960s and 70s, with the Druid Hills median landing around 1964. That means a lot of original or first-replacement openers are chain-drive units from a generation that used heavier steel gears and simpler circuit boards than what's sold today. When those fail, it's rarely sudden - the door starts reversing for no reason, the motor hums but doesn't pull, or the remote range shrinks to almost nothing before the unit quits outright.
Colder, damp mornings add strain to older gear sets that have already lost lubrication over the decades, so failures cluster in the colder months here. If your opener is original to a 1960s build and it's making a new grinding sound it didn't make last winter, that's the gear stripping, not a sensor issue - and it's worth a call before the door gets stuck halfway.
