While it helped to open and close your garage door, information technology as well meant you could open and shut any garage door in the neighborhood that also happened to have a similar system. This, of course, led to many humorous moments in TV shows or commercials where somebody accidentally picks up the remote control for the automatic door opener thinking it'due south a Boob tube remote, pushes a button and opens their neighbor's garage door.

These days, garage door openers are radios that work at 350 MHz. When you push button the button to open up your garage door, it not only transmits a radio signal, just that radio signal too includes an encoded binary number that solely works with the receiver in your garage. Your door will only open in one case your receiver "recognizes" your binary code number.

But criminals are catchy. Smart ones could utilise a radio to pick up the lawmaking, record information technology and and then play information technology back exterior your garage door to open up it and rob you lot. Fortunately, the people who industry garage doors are smarter than the criminals. Each fourth dimension you use a garage door opener, a new code is created. Both the transmitter and the receiver contain computer chips that recognize the new code each time.

What Are Garage Door Sensors and How Do They Work?

Another reason your garage door may not open is your garage door sensors are malfunctioning. Before we talk about the reasons why it happens and how yous can endeavor to fix a garage door sensor, permit's expect at what how they operate. Garage door sensors take ii essential elements:

• Photograph-eye: Garage door sensors work with the utilize of a photograph eye system. These infrared sensors are placed on either side of your garage door well-nigh 2 to six inches off the basis. When yous press the remote control you utilise to open your garage door, it sends a signal to the sensors to open the door. Simply the main purpose of the photo eyes is to prevent the door from closing on someone or something.
• The line of sight:  The photo eyes on either side of your door send an infrared beam to each other when the door is open and there is naught blocking it. The door will only close if the beam remains uninterrupted. But if a person, an fauna or a bike is in the way, and the beam is interrupted or blocked, the door will not close merely will reopen.

How Exercise I Decide If It's a Problem With the Garage Door Sensor?

If your garage door opens usually but then doesn't close or starts to close and then reopens without whatsoever obstructions in the fashion, there'south a proficient run a risk that your garage door sensor is malfunctioning. This could result in ii main problems.

• Dirty lenses: This is well-nigh likely the reason a garage door won't close. The well-nigh obvious solution to the problem may be the lenses are dirty. These lenses are made of drinking glass, much similar that used in a photographic camera lens. The photo eyes of door sensors are very small and get dirty hands over time. Employ a soft cloth with a mild cleaner that does not get out streaks. Gently wipe away dirt or residue from the surface of the heart. Don't overdo it, considering if you lot become the eye also wet, more dirt volition stick to information technology.
• Out of alignment:  Misaligned photograph eyes are another reason for malfunctioning garage door sensors. The photo eyes need to be pointed in the same direction, at the very same bending. There is an LED lite on the exterior of each sensor. If one of these lights is blinking, information technology means the sensor is out of alignment. Use a screwdriver to tighten the screws on the subclass belongings upward the blinking LED light until it is in alignment with the other one. You tin can besides exercise this by angle the bracket back into its original position. Once y'all realign the sensor lights, the blinking will cease.

Now it's time to exam your handiwork. Take another cardboard box and put information technology in front of one of the photo eyes. Press the remote control. If the door starts to close simply then reopens because the beam between the realigned photo eyes is now blocked, your mission is successful. If, however, the door continues to close and over again crushes the new cardboard box, you may accept a more serious trouble.

Check one more time to brand sure you accept cleaned the lenses properly, the photo eyes are aligned and no LED light is blinking. Endeavour the cardboard test one last time. If the door fails to return to the open position and closes on the cardboard box, information technology's time to call in a professional to take a look at the entire system.
