Parts For Chamberlain Garage Door Opener

Chamberlain garage door openers are a popular choice for homeowners thanks to their reliability, durability, and wide range of features. However, even the best garage door openers will eventually need to be repaired or replaced. When that time comes, it's important to have a basic understanding of the different parts of a Chamberlain garage door opener so that you can accurately diagnose the problem and order the correct replacement parts.

Motor

The motor is the heart of the garage door opener. It is responsible for providing the power to lift and lower the door. Chamberlain garage door openers use either a chain drive or a belt drive motor. Chain drive motors are less expensive, but they can be noisy and require more maintenance. Belt drive motors are more expensive, but they are quieter and require less maintenance.

Gear and Sprocket

The gear and sprocket are responsible for transferring power from the motor to the drive shaft. The gear is attached to the motor, and the sprocket is attached to the drive shaft. When the motor turns, the gear turns the sprocket, which in turn turns the drive shaft.

Drive Shaft

The drive shaft is responsible for transmitting power from the gear and sprocket to the trolley. The drive shaft is a long, metal rod that runs the length of the garage door opener. It is connected to the gear and sprocket at one end and to the trolley at the other end.

Trolley

The trolley is responsible for moving the door up and down. The trolley is attached to the drive shaft and moves along a track that is mounted to the ceiling of the garage. When the motor turns, the drive shaft turns the trolley, which in turn moves the door up or down.

Sensors

Sensors are used to detect obstructions in the door's path. Chamberlain garage door openers use either infrared sensors or photoelectric sensors. Infrared sensors emit a beam of infrared light, and if the beam is broken, the door will stop moving. Photoelectric sensors use a light emitter and a light receiver, and if the light beam is broken, the door will stop moving.

Remote Control

The remote control is used to operate the garage door opener from a distance. Chamberlain garage door openers use a variety of remote control technologies, including rolling code technology, which is the most secure.

Wall Control Panel

The wall control panel is mounted on the wall inside the garage and is used to operate the garage door opener manually. The wall control panel typically includes a button to open and close the door, a button to lock the door, and a button to program the remote controls.

Battery Backup

The battery backup is used to power the garage door opener in the event of a power outage. Chamberlain garage door openers use a variety of battery backup systems, including sealed lead acid batteries and lithium-ion batteries.
