Each type has a specific role in supporting the door’s movement.

Torsion vs. Extension Springs

Torsion Springs: These springs are mounted horizontally above the door and use torque to help lift the door. Torsion springs wind and unwind as the door opens and closes, counterbalancing the weight. Torsion springs are often considered more durable and safer than extension springs due to their controlled movement.
Extension Springs: Located along the sides of the door, extension springs stretch as the door closes and contract as it opens. While more affordable, they tend to have a shorter lifespan and may be prone to snapping under extreme tension if not maintained.

How Springs Counterbalance the Door’s Weight

Springs provide the necessary force to balance the weight of the garage door, making it easier to lift manually or with an opener. When the door is closed, the springs are under high tension; as the door opens, the tension is released, allowing the door to rise with minimal effort. This counterbalance system is crucial to prevent strain on the door opener and ensure smooth operation.

Safety Considerations When Dealing with Springs

Due to the high tension in both torsion and extension springs, handling them can be dangerous, especially during replacement or repair. Homeowners are strongly advised to seek professional assistance for any issues involving springs. Improper handling can lead to serious injuries, as springs can snap or release force unexpectedly.

Signs It’s Time to Replace Your Springs

Worn-out or broken springs are often indicated by certain telltale signs, including:

Difficulty Opening the Door: If the door feels heavier or struggles to open, it may signal spring failure.
Visible Gaps in the Springs: A gap in the coil of a torsion spring typically indicates it has snapped and requires replacement.
Loud Noise: A snapping sound or loud bang when operating the door could signify a broken spring.

Replacing springs at the first sign of wear can prevent further damage to other components and ensure safe, reliable door operation.
