How Garage Door Openers Work

The opener moves the door through a rail and drive mechanism, but it is not intended to carry the door's full weight. Springs counterbalance the door so the opener can guide controlled movement.

Why door balance matters

A healthy opener can still struggle if the spring system is broken or the door binds in the tracks. That is why opener diagnosis includes the mechanical condition of the door.
