Steps to Fix a Broken Garage Door Sensor

  1. Inspect for Physical Damages
    • Begin by visually inspecting the sensor. Check for obvious signs like broken or frayed wires, or damage to the sensor’s casing.
  2. Clean the Sensor Lens
    • Dust and debris can obstruct the sensor’s infrared beam. Gently clean the lens with a soft cloth or tissue.
  3. Realign the Sensors
    • Misaligned sensors are a common issue. Ensure that both sensors face each other directly and are at the same height.
  4. Check the LED Indicator Lights
    • Most sensors have LED lights that indicate their status. If one is off or blinking, it indicates a problem. Consult the manual for specific light patterns and their meanings.
  5. Test the Garage Door
    • After making adjustments, test your garage door to see if the issue is resolved. If not, continue troubleshooting or consider contacting a professional.
  6. Replace the Sensor
    • If none of the above steps work, your sensor may be faulty and need replacement. Always ensure you purchase the right sensor for your garage door model.
