Garage door sensors protect your family, possessions and pets by non allowing the heavy garage door to shut if there is anything in the glide path. They do this by using an electrical eye sensor that crosses the doorway. If the sensor doesn't receive the beam emitted by its contrary number, the door won't close. This seems similar a clever device until the components come out of alignment -- meaning the door won't shut at all. Fortunately, it'southward non difficult to realign the sensors and put things back into working order

Steps

  1. 1

    Turn off the power to your sensors by tripping the fuse for your garage. You lot'll notice this in your home's breaker box.[1]

    • You won't actually exist working with the electrical wiring, just it's ever best to be safe when working with electricity.

  2. ii

    Loosen the screws that mountain each of your garage door sensors. Don't take them all the mode out. Just loosen them plenty and then that the mounting brackets can slide upwards and down, but won't do and so unless yous intentionally move them.[2]

  3. 3

    Slide each garage door sensor downward so it is as low as possible without unscrewing the mounting brackets. [3]

  4. 4

    Necktie a string to one sensor and so that, if pulled across the garage doorway, it will run across the center of the sensor. [four]

  5. v

    Run the string across the garage doorway and tie to the opposite sensor. Position the knot so the string runs beyond the center of that sensor, too.[five]

  6. 6

    Lay a level so the bottom runs along the string. Check that the line of the string is level.

    • If the line of the cord isn't level, conform one or both garage door sensors by sliding the mounting bracket upward. Go on until the sensors are one time again level.

  7. 7

    Tighten the screws to secure the garage door sensors in their new position.

  8. 8

    Ostend that the string is level earlier finishing. The sensors may have come out of alignment when you tightened the screws.[six]

  9. 9

    Finish by removing the cord and turning the power to your garage dorsum on.

  • Question

    I sensor is greenish and the other yellow. Why is that?

    Community Answer

    The "orangish/cherry-red" center is putting out the infrared beam to the "dark-green" receiving middle. If the light-green is not lit or blinking, it needs to be adjusted until information technology is a steady ON greenish or the door will not operate.

  • Question

    I accept a wall-mounted controller to open and close my garage door. When I push the close button on the controller, I have to hold it downwardly until the garage door is completely closed. What can I adjust or ready to make the garage door shut with only a button of the button?

    Community Answer

    It sounds like your sensors are out of alignment. You are bypassing the safe past belongings the button down. Check to run into if the light on each sensor is on and then realign from there.

  • Question

    How loftier off of the ground should the garage door sensors be located?

    Community Answer

    They should be six-9" off the flooring, and make sure they're equal. There should be an LED indicator lite on the meridian or back of each unit of measurement that lights up when the sensors are parallel and aligned. You may have to suit the sensor brackets upward and downward or side to side to reach this.

  • Question

    Will the sensor stop the door from hit the acme of the car?

    Community Answer

    Yes, the laser sensor will detect the car and the door will stop moving.

  • Question

    When I close my electric garage door it keeps opening again, and each fourth dimension I hit the button to re-close it, it opens again until finally it stays closed. Most of the time this happens in the evening when it'south hot. The sensor lights at the bottom on each side are green & the other is yellow/red. What tin can I exercise?

    Community Answer

    It may or may not be the estrus. Information technology could be the time of the season or angle of the sun shining on the sensor.

  • Question

    Only one of the sensor lights is on. Practise I need to replace the sensor with the low-cal out?

    Community Answer

    Check the wiring from the non-working sensor to the opener. On my opener, the wire from the sensor splits in two at the opener and each wire connects to a different spiral. Try reversing how the wires are connected to the screws.

  • Question

    My garage door will not close when the sun shines in the doorway. I have to concord the button for it to close. Why does this happen?

    Community Answer

    This is because the sensors accept a broader low-cal spectrum than infrared, and the lite that comes from the sun completely blocks the receiver from capturing the infrared calorie-free from the sender. A college quality sensor might solve this problem.

  • Question

    How exercise I adjust and so that my garage door reverses when it hits a ii x four block that is laid apartment on the floor if my Genie garage door opener failed the safety opposite examination?

    Community Answer

    The safety contrary test is based on how much effort the motor that moves the door needs to apply to open or shut it. If it fails, it is because the garage door opener does not consider that the obstruction requires also much forcefulness to shut. Making sure that the belt that moves the door has the proper tension might help to mitigate this event.

  • Question

    What would crusade the sensors of a Genie garage door opener to glow reddish and green?

    Community Answer

    That indicates a normal function. The beam is detecting an object when the ruby-red led is blinking.

  • If y'all have a light amplification by stimulated emission of radiation level, you can use information technology instead of a string to align your garage door. In this case, you will set up the level aligned with one sensor, and so adjust the opposite sensor until the beam of your light amplification by stimulated emission of radiation level is hitting the sensor.

  • Proper height for a garage door sensor is 4 to half-dozen inches (10.two to xv.2 cm). Higher than that can miss many depression-lying objects, including pets. Lower is easy to stand up above with a pes on either side. If your garage door sensors are outside of this range, remove them entirely from the garage door frame and install, leveled, inside the safe zone.

Thank you for submitting a tip for review!
