Light Sensitive Garage Door Reverse Sensor

Garage door sensors work using an infrared beam of light.

Light sensitive garage door reverse sensor.

Garage door sensors utilize a photo eye sensor and a beam of infrared light that goes between the two units. The sensors are normally about 4 inches above the ground. Refer to the owner s manual to determine which is. The light is emitted from one side of the garage door to a receiving unit on the other side of the door.

Adjust the garage door opener mechanism. This system allows them to detect obstructions like your car or a kid on a bike. Garage door sensors work by shooting a beam of infrared light across the entrance of your garage to the sensor on the other side. If they re turned on in both the sensors then there is no issue with the power supply.

The units are placed near the ground on either side of the garage door. Should something block the beam they set the garage doors into a reverse motion to keep the door from hitting or crushing the object this explanation shows exactly why a garage door sensor is primarily a safety feature. As long as the beam isn t interrupted the door will open or close normally. If you find the lights turned off in one or both the sensors it indicates that there is a problem in power supply.

If the beam of light is interrupted while the garage door is closing the door will stop and rise back up. A common cause of a malfunctioning garage door sensor is lack of power supply. The infrared beam from the garage door opener sensors isn t able to be seen by human eyes. The sensors are located low on each side of the garage door and the 2 beams meet performing a connection.

If the path between the sensors is unbroken the door will open and close normally.
