If one of the safety sensors on your garage door is broken, it’s important to replace it as soon as possible to ensure the safe operation of your garage door. However, it’s not recommended to replace just one sensor.
The safety sensors on your garage door work as a pair and are designed to communicate with each other to ensure that the door doesn’t close if there is an obstruction in the path of the door. If one of the sensors is broken, it can’t communicate with the other sensor, and the safety feature will be disabled. This can lead to a potentially dangerous situation where the door could close on a person or object.
So, to ensure the safe operation of your garage door, it’s recommended that you replace both safety sensors as a pair. This will ensure that they can communicate with each other and properly detect any obstructions in the path of the door.
