Hobe Sound's housing stock centers on 1983, which puts a lot of openers here into their second or third replacement cycle rather than original equipment - chain-drive units are common, and chain-drive gear kits wear down over years of use in a way belt drives don't. The area sits in a mild temperate climate band, and while that sounds like an easy environment for a garage, the humidity swings that come with it are hard on circuit boards and on the lubrication in drive gears - moisture gets into connectors and logic boards degrade faster than the same part would in a dry climate.
We also see openers that are mismatched to the door they're lifting - a lighter-duty unit straining against a heavier insulated panel that got swapped in at some point without upgrading the opener. That combination shortens the opener's life regardless of the climate, and it's one of the more common things we find once the cover's off.
