Garage door sensors (sometimes called photo eyes) are small but important safety devices for your garage door. They help make using your garage door much safer.
These garage door sensors are usually installed on both sides near the bottom of the door. They send out an invisible beam of infrared light. If something or someone blocks this beam, the sensors will tell the sectional garage door to go back up instead of closing.
This article will go over some common reasons why your garage door sensors are not working and what you do next.
The Specific Performance of Sensor Faults
Cable broken device failure:
The cable broken device is an important safety device for sectional overhead doors. Its function is to prevent the door from falling during operation. If the cable broken device fails, such as the bracket is loose or damaged, it may cause the door to fall during operation, resulting in a safety accident.
Safety sensor failure:
The garage door safety sensor is a non-contact safety protection device that detects whether there are obstacles during the operation of the door body by emitting and receiving infrared rays. If the safety sensor fails, such as the infrared transmitting tube or receiving tube is damaged, the infrared rays are blocked, etc.. It may cause the motor's resistance rebound function not to work, making the automatic garage door impossible to close normally.These issues are common signs of garage door sensors not working, and they should be checked and fixed as soon as possible to keep the door safe to use.
Sensor Fault Detection Methods
Check the cable broken device:
Check whether the cable broken device is firmly installed & whether the bracket is in good condition. You can shake it by hand to check whether it is loose. If it is found to be loose or damaged, it should be repaired or replaced in time.
Check the safety sensor:
- Check whether the infrared transmitting tube and receiving tube are working properly. You can block the infrared rays with your hands and observe whether the motor will rebound when encountering resistance. If the motor does not reverse, it could be a sign of garage door sensors not working properly.
- At the same time, check whether the infrared transmitting and receiving circuits are in good condition; whether the circuits are damaged or short-circuited.Any issues here can also lead to garage door sensors not working and should be fixed immediately to keep the door functioning safely.
Solutions of Sensor Faults
Check the sensor connection line:
Check whether the sensor connection line is good, whether the line is damaged or short-circuited. If not good, please repair or replace it asap.Faulty wiring is a common cause of garage door sensors not working.
Clear obstacles on the sensor surface:
If there are obstacles blocking the sensor surface, clear the obstacles in time to ensure that the sensor can work normally. For example, for a safety sensor, if the infrared rays are blocked by dust, leaves, etc., it will not work successfully.Keeping the sensor area clean can help prevent garage door sensors not working issues.
