Garage door sensors are an essential safety feature for any garage door system. These sensors are designed to detect any movement or obstruction in the path of a closing garage door and immediately reverse the door's direction. This prevents accidents and damage to property or vehicles. Garage door sensors typically consist of two small devices installed on either side of the door, which communicate with each other using infrared technology. They are easy to install and can be a life-saving addition to any garage door system.

Frequently Asked Questions (FAQs)
1. How do I know if my garage door sensors are bad?
If your garage door opens normally but then doesn't close or starts to close and then reopens without any obstructions, it is likely that your garage door sensor is malfunctioning.
2. Should garage door sensors both be green?
Garage door sensors should ideally have a small light on each sensor. If both lights are green, it means that the sensors are aligned and in sync with each other. You can also test the system to confirm if the sensors are working properly.
3. What does it mean if one garage door sensor is red and one is green?
Each garage door sensor usually has a light. If one sensor has a green light, it indicates that the units are powered up, and the other sensor has a red light to show that there is no obstruction between the sensors and they are detecting each other.
4. What causes garage door sensors not to work?
Garage door sensors may not work properly due to a lack of power. This can be caused by a faulty power supply or issues with the sensor's components. Damaged wires, whether from wear and tear, pests, or weather elements, can also lead to sensor malfunction. If you notice damaged wires, it is best to replace them.
5. Why would garage door sensors stop working?
Garage door sensors can stop working due to damaged wires. Frayed or disconnected wires, as well as damage caused by pests or weather, can affect the functionality of the sensors. If you observe any damaged wires, it is recommended to replace them to ensure proper sensor operation.
