Garage Door Won't Close or Keeps Reversing in Atlanta, GA
When your garage door won't close - or starts down and then reverses back up - the safety sensors are the cause in the large majority of cases. These small photo-eye sensors near the floor on each side of the door must 'see' each other; if the beam is blocked, misaligned, or dirty, the opener refuses to close the door as a safety measure.
Other possibilities include an obstruction in the track, incorrect travel or force settings on the opener, or direct sunlight confusing the sensors.

Why garage doors reverse instead of closing
Modern garage door openers are required to reverse if they detect an obstruction, and they use infrared photo-eye sensors for this. If anything interrupts the invisible beam between the two sensors - a box, a cobweb, even a thick layer of dust - the door will start down, then immediately reverse.
The opener's logic board treats a misaligned or failed sensor exactly the same as a blocked one. That's why a door that reverses 'for no reason' is almost always a sensor issue rather than a motor problem.
How to check the safety sensors yourself
First, look at both sensors (usually mounted 4-6 inches off the floor). One should show a steady green light and the other a steady red or amber light. A blinking or dark light means that sensor isn't aligned or isn't getting power.
Wipe both lenses with a soft cloth, make sure nothing sits in the beam path, and gently adjust the sensor brackets until both lights burn steady. If sunlight hits a sensor directly at certain times of day - common with west-facing Atlanta garages - a simple shade over the sensor can solve late-afternoon reversing.
- Check both sensor lights: steady green plus steady red or amber is correct
- Wipe the lenses clean of dust, cobwebs, and grime
- Realign the sensors so they point directly at each other
- Clear the beam path of boxes, tools, and debris
- Shield sensors from direct late-day sunlight
- Inspect for pinched or chewed sensor wires along the wall
Other reasons a door won't close
If the sensors check out, look at the opener's travel and force settings - these can drift over time, especially after power outages. A door that closes partway and reverses may be hitting a bent track section or a roller that has jumped the track.
In rarer cases, a failing logic board misreads the sensors, or a broken spring changes the door's balance enough that the opener's force sensor trips. These need a technician's diagnosis rather than DIY adjustments.
When to call a professional
Call if the sensors won't stay aligned, the wiring looks damaged, the door reverses with a clear beam path, or the problem comes and goes unpredictably. A local pro can test the sensors, check the opener's force and travel limits, and rule out track or spring issues in a single visit.
