Having to hold down the button is a classic “something has interrupted the beam” symptom. Simply disconnecting the sensors will not bypass this behavior. If it did, then a sensor failure would cause the door to work anyway, creating a safety issue.

Why does my garage door only close when I hold the button?

If your garage door only closes when holding the button, it could be that the sensor eyes are dirty or damaged. Since these “eyes” resemble camera lenses, you have to be very careful when cleaning them, and you don’t want to leave the area smudgy and covered in strikes.

Why won’t my garage door close on its own?

Check the Sensors

If your garage door won’t close all the way, it’s probably an issue with your sensors. Garage door openers have safety lasers mounted near the floor by the tracks. These sensors detect when small children, pets, or obstructions block the garage door’s path, helping to keep everyone safe.

How do you reset garage door sensors?

Quote from the video:
Quote from Youtube video: So all you have to do is loosen up the wing nut. Here. And position the sensor. So that it is pointed to the other. Side of the garage.

How do you know if you have a bad garage door sensor?

Light indicators: An easy way to tell if your garage door sensors are out of alignment is by checking if the exterior LED light blinks when you attempt to close the door. Green lights mean the sensors are working, while red lights indicate the sensors are not aligned.

When I close my garage door it opens again?

If your garage door keeps going back up after you’ve closed it, the most common reason is because: The safety sensors are blocked. There are safety sensors at the bottom of your garage door. This infrared sensor passes a beam horizontally across the opening.

Why does my garage door go down and come back up?

Your garage door is programmed to travel a certain distance before it closes. If it closes before that distance has been traveled, it thinks something is wrong — and it reopens to help prevent any damage or safety risk.

Why is my garage door not closing and blinking?

Quote from the video:
Quote from Youtube video: The safety sensors use an invisible beam of infrared light to detect obstructions in the garage doors path. The sensors won't allow the door to close with their infrared being blocked.

What happens when garage door sensors go bad?

However, if the garage door sensors are bad, the door won’t stop until reaching and damaging the boxes. It is possible that the door entirely closes as if there are no boxes and destroys them. Additionally, it can close partially and reopen after hitting the boxes.

Where are garage door sensors located?

Garage door sensors are small, black boxes located a few inches from the floor on both sides of the garage door. Both sensors typically have indicator lights. One has a green light to indicate that the units are turned on.

Should both sensors on garage door be green?

Each sensor will usually have a light. One will have a green light, used to show that the units are powered up, and the other will have a red light to show that there’s no obstruction between the sensors and that they’re ‘seeing’ each other.

Why is one of my garage door sensors yellow and the other green?

Conclusion. If you’re seeing a yellow light on one or both of your garage door sensors, don’t worry, this is extremely common. The easiest way to fix this is to clean the lenses on both sensors and then make sure that they are perfectly aligned with one another.

What does it mean when one garage door sensor is green and one is yellow?

The amber light on the sending sensor will glow regardless of alignment or obstruction. (Meaning this light will always be on no matter what) If the green light on the receiving sensor is off, dim, or flickering (and the invisible light beam path is not obstructed) , alignment is required.

What does it mean when the garage door sensor is yellow?

The garage door sensor yellow light and the green light together create a solid illumination. If you do not see a solid illumination or your garage door is not working, the problem is most likely due to the sensors being out of line.

Should both garage door sensors be lit?

Safety Reversing Sensors are Obstructed or Misaligned

Locate the safety reversing sensors on both sides of your garage door. Make sure nothing is blocking the sensors. Once you’ve removed any obstructions, the LEDs in both sensors should glow steady.

Can you override garage door sensors?

Since most photo eye sensors are placed at that two-inch height, most people know you can simply step high above the infrared light to bypass the system. The garage door will continue to close if your steps avoid the photo eye sensor. Disconnecting the garage door opener from the garage door will bypass the sensors.

How can I get my garage door to work without sensors?

Quote from the video:
Quote from Youtube video: So they're always sensing each other with no obstructions in between. That will allow the opener to work without actually having the sensors mounted where they're intended to be mounted.

How do you trick garage door sensors?

So, all you need to do is hold the wall button down ( do not press and release). You must hold the wall button all the way down until the garage door hits the floor then release. If you let go of the button before the door hits the ground the sensors will kick back in to action and the door will reverse.
