Troubleshooting Liftmaster Garage Door Sensor Issues:

Understanding the Importance of Garage Door Sensors:

  1. Safety Features:
    • The yellow and green sensors work together to ensure the safety of the garage door operation. If an obstacle is detected, the sensors communicate with the opener to prevent the door from closing.
  2. Preventing Accidents:
    • Properly functioning sensors prevent accidents and injuries by stopping the garage door from closing on objects, pets, or people in its path.
  3. Smooth Operation:
    • When both sensors are aligned and free from obstructions, the green light indicates that the garage door system is ready for smooth and efficient operation.
