A garage door sensor is a safety feature that detects obstructions in the path of a closing garage door. It helps prevent the door from closing on vehicles, pets, or people. Most modern garage doors are equipped with two sensors:
- Safety Sensors: These detect if something is blocking the door’s path and prevent the door from closing.
- Security Sensors: These connect to the garage door opener to ensure the door is properly aligned and functioning.
When these sensors fail to operate correctly, the garage door may not function as it should, leading to the need for a bypass.
