Here are some steps to fix a garage door sensor issue based from Garland Garage Door:

  1. Check the alignment of the sensors: The first step is to make sure the sensors are aligned properly. The sensors are located on both sides of the garage door, about 6 inches off the ground. Check to make sure they are pointed directly at each other and there is nothing obstructing the path between them. If they are not aligned properly, adjust them until they are facing each other directly.
  2. Clean the sensors: Sometimes the sensors can get dirty or dusty, which can interfere with their operation. Use a soft cloth or a cotton swab to gently clean the lenses of both sensors. Avoid using harsh chemicals or abrasive materials, as these can damage the sensors.
  3. Check the wiring: If the sensors are aligned properly and clean, the next step is to check the wiring. Make sure the wires are not damaged or disconnected. If you notice any damage, you will need to replace the wiring. Also, check the wiring connections at the motor unit to make sure they are secure.
  4. Test the sensors: Once you have checked the alignment, cleaned the sensors, and inspected the wiring, it’s time to test the sensors. Open and close the garage door to see if the sensors are working properly. If they are still not working, you may need to replace one or both of the sensors.
  5. Replace the sensors: If the sensors are still not working, you may need to replace one or both of them. Most sensors can be purchased at your local hardware store or garage door dealer. Follow the manufacturer’s instructions to replace the sensors, making sure to align them properly and connect the wiring correctly.

Overall, as stated in Garland Garage Door, fixing a garage door sensor issue can be fairly straightforward with these steps. However, if you encounter any difficulties or are unsure about your ability to safely make the repairs, it’s always best to contact a professional garage door technician for assistance.
