Why does my garage door reverse before it closes in Franklin?

Start at the eyes, then at the settings

The pair of eyes face each other about six inches above the slab, and the receiver carries an indicator that should sit steady rather than flicker. Anything that interrupts or weakens the beam reads as an obstruction: a bag of mulch, a bin, pollen film on a lens, a bracket knocked out of line by a car door, or a staple driven through the low-voltage wire during some other job. Nudged brackets are the most common of those and the quickest to rule out.

With a clean, steady beam the head is making the call by itself. Down force wound too low trips on the ordinary friction of a cold morning, and a limit set past where the floor actually is drives the door into concrete, which reads as an obstruction and sends it back up. Both are adjustments on the head. Neither is a place to add force so the door shoves through something real, because that setting is precisely what the protection uses to recognize a strike.

This misreading of a limit setting shows up on the same call whether the door sits in Franklin proper or out along the drives toward Arrington and College Grove, where longer runs and detached bays give the pros we connect you with more slack to check before blaming the eyes. Toward Leiper's Fork on Old Hillsboro Road, older gravel-and-frost-heaved aprons shift the floor point enough that a limit set once in spring needs resetting by fall.

Ten pounds by hand, and what that proves

Close the door, pull the emergency release, and lift it yourself. A balanced door needs about ten pounds of hand effort and sits where you leave it at chest height. One that fights you, snatches at a particular point in the travel, or slides back down the moment you let go has a counterbalance or a track problem, and the head has been telling the truth all along. Fitting a sensor pair or a board to cure a spring fault is the costliest wrong turn available in this trade.

Franklin garages built near the Public Square and out toward Downtown Franklin along Main Street show the same reversing fault once a spring or roller starts to go, no matter how close to the Williamson County Courthouse they sit. The licensed pros we connect you with see it just as often on off-track calls in Nolensville and cable jobs out in Cool Springs, where the same worn hardware gets blamed on the sensors first and the spring second.
