Garage door sensors are one of the most important safety features in your system. They prevent the door from closing if something—or someone—is in the way. But when sensors malfunction or fall out of alignment, your garage door may stop working altogether. Here’s how to recognize sensor problems and what you can do to fix them.
What Do Garage Door Sensors Do?
Sensors use infrared beams to detect obstacles in the door’s path. If the beam is blocked or misaligned, the system automatically stops or reverses the door. This safety function protects children, pets, and vehicles from accidents.
Common Signs of Sensor Issues
Door Won’t Close Completely
The most common symptom of misaligned or faulty sensors.
Flashing Lights
Many openers flash an indicator light when there’s a sensor error.
Intermittent Operation
Sometimes the door closes, sometimes it doesn’t—usually a sign of loose wiring or poor alignment.
Dirty or Blocked Lenses
Dust, spider webs, or debris on the sensor lenses can trigger false readings.
Easy Fixes You Can Try
- Clean the Sensors – Wipe lenses with a soft cloth to remove dust or buildup.
- Check for Obstructions – Make sure nothing is blocking the beam near the garage floor.
- Realign the Sensors – Loosen the brackets, adjust until the indicator lights are steady, then retighten.
- Inspect the Wiring – Look for frayed or disconnected wires leading to the sensors.

FAQs
How often should I check my garage door sensors?
Test them monthly to make sure they stop the door when the beam is interrupted.
Can sunlight affect my sensors?
Yes, direct sunlight can interfere with infrared beams. Shielding or professional adjustment can solve this.
How do I know if my sensors are misaligned?
If the indicator lights are blinking or not lit at all, they’re likely out of alignment.
Can I replace the sensors myself?
While possible, wiring and calibration are best handled by a professional for proper safety.

The issue may be with the opener, springs, or wiring. Call a technician for a full inspection.
