Overview of garage door sensors and their importance

Garage Door Sensor Troubleshooting: Common Issues and Solutions - Overview of garage door sensors and their importance

Garage door sensors are essential components of a garage door system, providing safety and functionality. These sensors, typically located near the bottom of the door tracks, work together to detect any obstructions in the path of a closing garage door. They use infrared technology to send and receive signals. When an object, such as a person or a vehicle, breaks the beam between the sensors, the door automatically reverses direction to prevent accidents or damage.

Garage door sensors are crucial for ensuring the safety of your family and possessions. They prevent the door from closing on people, pets, or objects that may be in the way. Without properly functioning sensors, the risk of accidents and property damage increases significantly. Therefore, it is vital to regularly inspect and troubleshoot any issues with your garage door sensors to maintain their effectiveness and safeguard your home.

Common signs of garage door sensor issues
