A garage door opener is a handy device designed to make the process of opening and closing garage doors easier. It works using a combination of mechanical and electrical components. When you press the button on your garage door remote or wall-mounted control panel, a signal is sent to the opener. The opener, which is typically mounted on the ceiling of the garage, receives the signal and activates a motor. This motor then pulls on a chain or a belt, causing the door to either slide up or roll up along tracks. The opener’s motor is equipped with sensors that detect when the door is fully open or closed, ensuring safe operation. These sensors help prevent the door from closing if something or someone is blocking its path. This way, a garage door opener provides convenience and security for homeowners, allowing them to easily access their garage with just a push of a button.
Types of Garage Door Openers
There are several types of garage door openers available on the market today, each offering different features and functionalities. Understanding the different types can help you choose the right one for your needs. Here are the most common types of garage door openers:
- Chain Drive Garage Door Openers
- Belt Drive Garage Door Openers

Let’s take a closer look at each type and how they work.
1. Chain Drive Garage Door Openers
Chain drive garage door openers are the most common and affordable type of opener on the market. They operate using a metal chain that pulls or pushes the garage door to open and close.
The chain is connected to a motorized trolley that moves along a rail. When you activate the opener, the motor turns the chain, which in turn moves the trolley. This movement then pulls or pushes the garage door along the rail, allowing it to open or close.
Chain drive openers are known for their durability and reliability. However, they can be a bit noisy due to the metal-to-metal contact between the chain and the rail.
While they are suitable for most residential garage doors, chain drive openers may not be the best choice if your garage is located near living spaces, as the noise can be disruptive.
It is important to regularly lubricate the chain and maintain the opener to ensure proper functioning and prevent any potential issues.
Some popular chain drive garage door opener models include Genie Chain Drive Garage Door Opener and Chamberlain Chain Drive Garage Door Opener.
