Overview
Garage door openers fail for a handful of predictable reasons: worn drive gears inside the motor housing, a chain or belt that's stretched or jumped its track, a logic board that's taken a power surge, or photo-eye safety sensors that have drifted out of alignment or gotten knocked by a stored bike or trash can. We work on chain-drive, belt-drive, and screw-drive units from every major brand, including LiftMaster, Chamberlain, Genie, Craftsman, and Linear.
When You Need This
Common symptoms we see: the opener hums but the door doesn't move (often a stripped internal gear), the door reverses immediately after closing (almost always a photo-eye sensor issue), the remote works inconsistently (failing logic board or interference), or the unit is simply old enough that parts are no longer supported. If your opener predates 2010, it likely lacks the rolling-code security and battery backup features that newer units have, and after years of Jacksonville's humid summers, the circuit board is a more common point of failure than people expect.
