Garage Door Won't Close in Chattanooga? Same-Day Fix

**1. Misaligned safety sensors.** The two photo-eyes 6 inches off the floor must see each other. If one LED is blinking or off, the opener refuses to close. Spider webs, lawn debris, a bumped bracket, or sun glare are the usual culprits.

**2. Dirty or blocked sensor lens.** A film of dust over the lens can scatter the beam enough to trigger reversal. We clean and re-align in minutes.

**3. Limit switch out of adjustment.** If the opener thinks the door has already hit the floor before it actually has, it stops and reverses. Common after a spring replacement or roller swap.

**4. Broken torsion spring.** If the door feels heavy or the opener strains and gives up, the spring is gone. Forcing it will burn out the motor.

**5. Track obstruction or bent track.** A pebble, ice chunk, or dent in the track stops the door mid-travel and the opener auto-reverses for safety.

Look at both sensor LEDs—both should be solid (one usually green, one red). If one is blinking, gently re-aim it until both go solid. Wipe both lenses with a soft cloth. Check the tracks for anything blocking the door's path. Pull the red emergency release and try lifting the door by hand—if it won't stay halfway open on its own, you have a spring problem, not an opener problem.

If both sensors are aligned, the tracks are clear, and the door still won't close—or if you hear grinding, see a gap in the torsion spring, or the door is hanging crooked—stop using it. Call 423-583-9355 for same-day diagnosis and repair across Chattanooga.
