Garage door sensors are an essential safety feature that prevents the garage door from closing if there’s something in the way. They work by sending a beam of infrared light across the opening of the garage. If anything interrupts this beam, it signals to the garage door opener not to close. However, like any other device, they can run into problems and may need troubleshooting now and then.
One common problem is when your garage door won’t close all the way or reverses immediately after touching down. This could be due to misaligned sensors which interrupt their own infrared signal. To solve this issue, you must check each sensor’s alignment. Usually, they have small LED lights that indicate whether they’re aligned correctly or not – one will typically blink if it’s out of alignment while the other remains steady. You can adjust them by gently pushing them up or down until both lights stay on continuously.
Another issue is when your garage door refuses to close even though there’s nothing blocking its path. This might be because dirt or debris has accumulated on the lens of your sensors and is blocking their infrared beam. A simple solution for this problem is cleaning each visit our blog sensor with a soft cloth and mild cleaner.
A more serious problem occurs when your garage door doesn’t respond at all despite having power supply and being properly aligned; this could mean faulty wiring between your sensors and the motor unit controlling your garage doors’ operation. For such cases, unless you’re experienced in electrical repairs, it would be best to call a professional technician who can safely handle these wires without causing further damage.
Lastly, if you notice intermittent operation where sometimes it works perfectly fine but other times it doesn’t respond at all even if nothing seems wrong with alignment or cleanliness of lenses – chances are you might have defective sensors that need replacement altogether.
In conclusion, while these issues may seem daunting initially especially for those who aren’t technically inclined – most common problems with garage door sensors are relatively easy to diagnose and fix. Regular maintenance like cleaning the lenses and checking alignment can prevent many of these issues from occurring in the first place. However, when it comes to more complex problems involving wiring or replacement of parts, always remember that safety should be your top priority so don’t hesitate to call a professional if needed.
