Replace the garage door opener gear and sprocket assembly

As the drive shaft and sprocket rotate, they drive the trolley that lifts and lowers the garage door. The plastic gear on the drive shaft is designed to fail if the garage door gets stuck in the travel tracks, protecting the expensive drive motor from damage. If the gear is worn or damaged, the door won't move properly. Replace the gear shaft and sprocket assembly if it's damaged or worn out.

Made of plastic, the worm and drive gears strip out to protect the motor from damage if the door suddenly hits an object in its travel path. Replace the drive and worm gears if they're worn or stripped.
