Garage Door Won't Close? Check Your Safety Sensors First

A garage door that reverses for no reason, refuses to close, or blinks its opener light at you is not usually a motor problem. Nine times out of ten it is the safety sensors. Every opener made since the mid 1990s has two small sensors, one on each side of the track a few inches off the floor. They shine an invisible beam across the opening. Break that beam while the door is closing and it has to stop and reverse. That is the law, and it is what keeps the door from closing on a kid, a pet, or a bike left in the way. Common causes of sensor trouble: Misalignment. A bumped sensor, even slightly, throws off the beam. This is the most frequent fix and sometimes takes five minutes. Dirty lenses. Dust, cobwebs and lawn clippings block the beam the same way an obstruction would. Loose or corroded wiring. Garages get damp, and connections corrode over time. A failed sensor. LEDs that will not light at all usually mean the unit itself needs replacing. If the indicator lights are solid but the door still will not close, start with alignment and a wipe-down before assuming the worst. If that does not fix it, the sensors themselves likely need replacing.
