Safety sensors for Garage Door Safety Sensors function by employing an infrared beam that is utilized to sense obstructions in the route of a closing door. You can usually find these sensors placed near the lower section of door tracks, on both sides. Such sensor units generally comprise two parts: a sending device and a receiving one.
The transmitter sends out a beam of infrared light and it goes across the doorway to reach the receiver on the opposite side. In case no blockage happens, the door will close as usual. But if something like an object or a person/pet cuts through this beam then these sensors send a signal to the opener to stop or reverse direction of door movement so accidents can be avoided.
Common Garage Door Sensor Problems
Common problems with garage door sensors, though they are dependable, can affect their operation. One problem that happens often is misalignment. If the sensors are not perfectly aligned, the infrared beam might not reach its receiver and this causes the door to stop or reverse. This situation can occur when the sensors get knocked or if the brackets holding them loosen up.
A usual issue is sensors being dirty. Dust, dirt, and other things can be collected on the lenses of the sensor. This stops the infrared beam from reaching across to its matching sensor, causing a malfunction in it.
Additionally, problems with wiring might interfere with communication between these two parts: the opener and sensors which could lead to either an off-and-on or full shutdown of sensing abilities.
How to adjust garage door safety sensors
When you learn how to adjust garage door safety sensors, it can fix a lot of frequent problems. You should first inspect the alignment. Look at the sensors and see if they are facing each other straight. Typically, most sensors come with indicator lights to assist in alignment. If the alignment is correct, each sensor’s light will be stable.
Then, wipe the sensors with a gentle cloth to eliminate any dirt, dust, or unwanted substances. Do not use strong chemicals that might harm the lenses. Confirm that the sensors are properly placed and fasten any loose screws or brackets to prevent them from being misaligned.
Change the height of the sensors if required. Normally, we put them at a similar level which is usually 6 inches from the ground. Use a measuring tape to make sure and adjust accordingly. Remove any items or dirt that might obstruct the infrared beam from reaching the receiver.
Conclusion
Grasping adjusting garage door safety sensors, identifying typical issues with garage door sensors and learning adjustments for them can assist you in keeping your garage door system safe and operational. Regular maintenance and quick handling of sensor problems will ensure that your garage door’s functioning remains smooth and secure for many years ahead. When you keep your sensors clean, in line, and free from things blocking them, it helps to prevent accidents while also maintaining the life span of your garage’s entrance system.
