Light Sensitive Garage Door Reverse Sensor

Adjust the garage door opener mechanism.

Light sensitive garage door reverse sensor.

The units are placed near the ground on either side of the garage door. Do both garage sensors need to be green. If the beam of light is interrupted while the garage door is closing the door will stop and rise back up. On the garage door motor there will be two knobs or dials to adjust the opener and the reverse sensor.

If you find the lights turned off in one or both the sensors it indicates that there is a problem in power supply. 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. As long as the beam isn t interrupted the door will open or close normally.

This system allows them to detect obstructions like your car or a kid on a bike. The light is emitted from one side of the garage door to a receiving unit on the other side of the door. Garage door sensors utilize a photo eye sensor and a beam of infrared light that goes between the two units. 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.

Look for small led lights on the sensors. The sensors are normally about 4 inches above the ground. 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.

Garage door sensors work using an infrared beam of light.
