A door that runs all the way down and then rides straight back up has tripped its own reverse. As far as the opener is concerned, something was in the way at floor level. Sometimes there is. Sometimes it has simply been given a reason to believe it, and the quickest way to tell those apart is to notice when the door does it rather than what it does.
First question: does it only do this at certain times of day
If the door closes fine in the morning and refuses at five in the afternoon, look at the sun before you look at the opener. Low winter sun coming straight into a west-facing opening can flood the receiving photo eye with infrared and swamp the beam it is meant to be reading. The opener sees the signal drop and stops the close. Nothing is broken. Shading the receiver, or swapping the sender and receiver ends so the receiver faces away from the light, deals with it for good. Cool Springs and the newer subdivisions have plenty of west-facing three-bay openings where this shows up for a few weeks either side of the shortest day.
Watch whether the door actually touches the concrete
Stand inside and watch the last foot of travel. Contact with the slab followed by a reverse means the fault is mechanical or a limit setting. A reverse in mid air with clear space under the door means the safety sensors lost each other, so the lenses, the brackets and the low-voltage wiring along the track are where to look.
A seal that has gone hard stops compressing
The rubber strip along the bottom of the door is a wear part. It works through a humid summer and then a winter of freeze and thaw crossings, and cheap vinyl eventually turns into a stiff bar that no longer squashes. The door lands on it early, motor current spikes, and the reverse fires exactly as designed. Press a thumb into it: good rubber gives, spent rubber does not. Weather seals at the bottom and the jamb stops are an estimated $105 to $235 fitted, and a seal in a retainer packed with grit will never seat properly until the channel is cleaned out.
The stored floor position drifts
Openers keep a down limit in memory. When that stored point sits below where the door now lands, the motor keeps driving after the door has stopped moving, the current climbs, and the safety reverse does its job. Openers drift into this on their own. So do doors, once a new torsion spring changes the balance or a fresh seal changes the height the door seats at. Any decent visit resets both travel limits and the force to how the door moves that day rather than how it moved three years ago.
Sweep the threshold before anyone comes out
Gravel, a dropped screw, a hardened ridge of mud, a garden cane leaning against the jamb. All of them will stop a door and send it back up, and all of them are free to rule out. While you are down there, look along the closed door for daylight. A door that seals on one bottom corner and leaves a wedge at the other is not a seal problem, it is a geometry problem, and it wants the tracks and the header looked at together.
Never tape the sensors facing each other
Aiming the pair at each other on a shelf, or clamping the wall button down, defeats protection that has been mandatory on residential openers since the early 1990s under UL 325 and 16 CFR Part 1211. The Consumer Product Safety Commission asks for a monthly reversing test against a flat piece of timber on the slab for the same reason. A door that reverses when it should not is a nuisance. A door that does not reverse when it should is a different category of problem.
This one is a standard rate job
A door that reverses is up rather than open to the street, so the house is not exposed while it waits. A same-day or next-morning slot at the standard rate is the right call, and the after-hours premium is best saved for the night a door will not close at all. A safety sensor pair is an estimated $95 to $195, weather seals an estimated $105 to $235, and opener repair an estimated $129 to $315. Guide bands, not quotes. Ring (615) 759-0548 and describe which of the behaviors above your door is doing, because that decides what goes on the van.
This reopen-then-reverse pattern turns up on driveways where the door faces a slight grade, and Franklin has plenty of them: garages near Downtown Franklin off Main Street, homes toward Cool Springs along the busier retail stretches, and older lots closer to the Public Square where slabs have settled unevenly over the years. A misaligned sensor pair or a failing close-force setting reads the resistance as an obstruction and throws the door back up. Call and describe exactly when it reverses.
Reversal complaints out of Franklin often trace back to the sensor brackets themselves, especially where driveway slopes push installers into odd mounting angles. The pros we connect you with see it near the Governors Club gatehouse along Wilson Pike, where longer drives and stone piers can leave brackets slightly twisted, and out toward Legends Ridge Drive off Sunset Road, where newer construction sometimes rushed the alignment. Either way, a fraction of an inch is enough to trigger the reverse.
Temperature swings play a role too, and the licensed pros we connect you with notice it near Stream Valley off Lewisburg Pike, where humidity off the West Harpeth River causes seasonal swelling that throws off the safety reversal, and again out toward Sullivan Farms near Donelson Creek Parkway, where newer slabs settle unevenly under the track. Franklin's mix of older foundations and fresh construction means the same fraction-of-an-inch misalignment shows up for very different reasons depending on the street.
