For homeowners, understanding how their garage door sensors work can be crucial in maintaining a safe and efficient home. Have you ever wondered why is one garage door sensor green and one red? These indicators are more than just lights; they are an important component of a larger safety mechanism. The colors play a vital role in ensuring that your garage door system operates correctly.
Garage doors are intricate systems that require precise calibration and components to function smoothly. Among these components, garage door sensors are critical for safety. Learning why one sensor is green and one red can help you diagnose issues and maintain your garage door system in optimal condition.
Understanding Garage Door Sensors
The first step in answering the question why is one garage door sensor green and one red is to understand what garage door sensors are and how they function. These sensors are usually located on both sides of the garage door, near the bottom.
Role of Garage Door Sensors
Garage door sensors are safety devices that ensure the door does not close on any object, person, or pet. They stop the door’s downward movement if something is in its path.
