Understanding Garage Door Mechanisms
What Is a Garage Door?
A garage door is a large door that opens either manually or automatically to provide access to a garage. It can be made from various materials, including steel, wood, and aluminum, and comes in different styles such as:
- Sectional
- Roll-up
- Slide to the side

How Does It Work?
Most modern garage doors operate using an automatic opener, which consists of several key components:
- Remote Control: Sends a signal to the opener to activate the door.
- Opener Motor: Powers the mechanism that lifts or lowers the door.
- Track System: Guides the door as it moves up and down.
- Safety Sensors: Detect obstacles to prevent the door from closing on objects or people.
Main Purpose
The primary purpose of a garage door is to provide security and convenience. It protects your vehicle and belongings from theft and weather while allowing easy access when needed. However, when it starts to open and close by itself, it raises several concerns that need to be addressed immediately.
