If you observe any irregularities with these lights, such as dimness or blinking, it may signal an underlying issue with the sensor's connection or alignment.

In addition to false alarms and indicator light problems, if your garage door reverses unexpectedly during operation, this could also be attributed to faulty sensors. When working correctly, garage door sensors detect obstacles in the door's path and prevent accidents by prompting the door to reverse its movement. However, malfunctioning sensors may fail to detect these obstacles accurately, leading to unsafe situations where the door reverses without reason.



  • Malfunctioning sensors can compromise home security.

  • Repairs or replacements can be costly if not addressed promptly.

Remember that addressing sensor issues promptly is crucial for maintaining a safe and functional garage door system. Regular maintenance checks and prompt repairs can help ensure that your garage remains secure and operates smoothly at all times.
