Signs Your Garage Door Spring May Be Broken
The Door Suddenly Feels Extremely Heavy
The spring system carries much of the door's weight. When a spring fails, the door can become difficult or unsafe to lift.
You Heard a Loud Bang From the Garage
A spring can release suddenly when it breaks and may produce a loud bang even when nobody is operating the door.
The Motor Runs but the Door Won't Open
A garage door opener is not designed to lift the full weight of an unbalanced door. A failed spring can cause the motor to struggle or stop.
The Door Opens Only Partway
The opener may begin lifting the door before stopping because the spring system is no longer providing sufficient assistance.
The Door Looks Uneven
A spring, cable or related lifting problem may cause one side of the door to sit or move differently from the other.
A Visible Gap Has Appeared in the Spring
On some torsion spring systems, a visible separation in the spring can indicate that it has broken.
Can I Keep Using My Garage Door With a Broken Spring?
We recommend stopping operation of the garage door if a spring has broken or the door has suddenly become unusually heavy or unbalanced. Continuing to operate it can place additional load on the opener, cables, drums and other components.
Garage door springs operate under significant stored tension. Do not attempt to dismantle, tension or replace a spring unless you have the appropriate equipment, training and experience.
Call 08 6256 4417 for spring repair assistanceWhat Type of Garage Door Spring Do I Have?
Torsion Springs
Typically mounted on a shaft above a sectional garage door. The spring twists to help counterbalance the weight of the door.
Extension or Side Springs
Common on some tilt and older garage door systems. These springs stretch as the door operates.
Roller Door Spring Systems
Roller doors use a different spring arrangement, typically integrated into the drum/barrel assembly.
Not every spring problem uses the same part or repair procedure. The correct spring must be selected for the specific door weight, size and configuration.
Why Do Garage Door Springs Break?
Normal Wear
Every opening and closing cycle places stress on the spring.
Corrosion
Moisture and corrosion can weaken spring material over time, particularly in exposed environments.
Incorrect Spring Selection or Tension
A spring that is incorrectly matched or tensioned can affect door balance and component life.
Heavy Daily Usage
Doors used many times every day accumulate spring cycles faster than lightly used residential doors.
Problems Elsewhere in the Door
Damaged cables, drums, tracks, hardware or poor door balance can place abnormal stress on the lifting system.

Can a Broken Spring Damage the Garage Door Motor?
A garage door opener is designed to move a properly balanced door. If the spring system fails, the opener may be forced to lift far more weight than intended. Continuing to operate the door in this condition can place additional stress on the motor and drive system. If the opener has been affected, see our garage door opener repair service.
Springs and Garage Door Cables Work Together
On many sectional garage doors, the springs, drums and lifting cables work together as one counterbalance system. When one component fails, the others should be inspected for related damage or loss of tension. For cable faults, see our garage door cable repair service.
If the door is stuck and you need urgent help, we also provide emergency garage door repair. You can also view our full range of garage door repairs in Perth.
Should Both Garage Door Springs Be Replaced?
Some garage doors use a pair of springs. Whether one or both should be replaced depends on the door configuration, the condition and age of the remaining spring, and the specifications of the replacement system.
The technician should inspect the complete spring setup before recommending the appropriate repair.
Can a Broken Garage Door Spring Be Repaired?
A physically broken spring is generally replaced rather than repaired or joined back together. If the problem relates to tension, balance or another component rather than an actual break, the technician can identify the cause during inspection.
