On the garage door motor there will be two knobs or dials to adjust the opener and the reverse sensor.

Light sensitive garage door reverse sensor.

Adjust the garage door opener mechanism. Garage door sensors work by shooting a beam of infrared light across the entrance of your garage to the sensor on the other side. A common cause of a malfunctioning garage door sensor is lack of power supply. 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.

Garage door sensors utilize a photo eye sensor and a beam of infrared light that goes between the two units. The light is emitted from one side of the garage door to a receiving unit on the other side of the door. If the path between the sensors is unbroken the door will open and close normally. The sensors are normally about 4 inches above the ground.

Garage door sensors work using an infrared beam of light. The sensors are located low on each side of the garage door and the 2 beams meet performing a connection. Do both garage sensors need to be green. Refer to the owner s manual to determine which is.

If they re turned on in both the sensors then there is no issue with the power supply. If you find the lights turned off in one or both the sensors it indicates that there is a problem in power supply. The infrared beam from the garage door opener sensors isn t able to be seen by human eyes. Look for small led lights on the sensors.

If the beam of light is interrupted while the garage door is closing the door will stop and rise back up.
