Why Is Your Garage Door Reversing in the Fall? (Blame the Autumn Sun!)

Have you ever pressed your garage door remote on a crisp autumn morning in Central Ohio, only to watch the door start closing, stop halfway down, and immediately reverse back open with the opener light flashing?

Before you assume your opener motor died or your springs snapped, take a look outside. The culprit might be hanging 93 million miles in the sky: sun glare.

As autumn arrives across Columbus, Orient, and Grove City, the sun shifts lower in the southern horizon. That angle change causes direct sunlight to blindingly hit your garage door’s photo-eye safety sensors. At Grove City Garage Door Inc., our 3-person local team receives calls every September and October about this exact mystery.

Here is why low autumn sunlight tricks your garage door safety sensors—and how to fix it safely without risking family safety.

How Sun Glare Blinds Your Safety Sensors

Modern garage door openers rely on two safety sensors mounted 4 to 6 inches above the garage floor on either side of the track:

  1. The Sending Sensor: Emits an invisible infrared light beam.
  2. The Receiving Sensor: Detects that infrared light beam.

When the light beam is unbroken, your garage door closes smoothly. If a child, pet, or obstacle breaks the beam, the door automatically reverses to prevent injury or damage.

The Fall Sunlight Problem: During the fall months, the angle of the sun drops dramatically during early mornings and late afternoons. Direct sunlight strikes the receiving sensor at the exact wavelength as the infrared light beam. The receiving sensor gets overwhelmed by the brightness, loses track of the sender’s beam, and assumes something is blocking the door.

Result? The opener triggers an emergency reversal and flashes its lights.

How to Fix Sun Glare on Safety Sensors Safely

When dealing with photoelectric safety sensors, safety must always come first. Never bypass, disable, or attach unsafe DIY sun shields (such as taped cardboard, makeshift plastic tubes, or tin foil) to your safety sensors. DIY shields can catch on the door tracks, interfere with mechanical travel, or fail during an actual safety emergency.

Here are safe, effective ways to handle low autumn sun interference:

1. Clean the Lenses First

Fall weather brings falling leaves, dust, and spider webs. A dirty or smudged lens exacerbates sunlight refraction. Wipe both sensor lenses gently with a soft microfiber cloth and mild glass cleaner.

2. Check for Proper Sensor Alignment

When sunlight hits the sensors, even a tiny misalignment can prevent the beam from registering.

  • Inspect the small indicator LED lights on each sensor body.
  • If either light is flickering or completely dark, your sensors are slightly out of alignment.
  • Gently loosen the wingnut or bracket, adjust the sensor until the indicator light shines solid, and retighten.

3. Swap the Sending and Receiving Sensors

This is often the best permanent fix! Only one of your two sensors is the “receiving” unit vulnerable to direct sunlight.

  • Identify which side of your garage door receives direct, blinding sunlight during peak morning or evening hours.
  • Disconnect power to your opener unit.
  • Swap the physical positions of the sending sensor and receiving sensor so that the receiving sensor sits in the shaded side of the garage opening.
