Common signs include a loud bang from the garage, a visible gap in the torsion spring, loose cables, or a door that only opens a few inches. The door may also feel unusually heavy because the spring is no longer counterbalancing its weight. Clopay’s spring guide

You should stop operating the door until the spring has been replaced. Using the opener can overload its motor or damage the gears, while attempting to lift the door manually can be dangerous because residential garage doors are much heavier than they appear. DASMA safety guidance

If both springs were installed together, replacing them as a pair is often the more dependable option. They have completed approximately the same number of cycles, so the second spring may be close to failing, and a properly matched pair helps keep the door balanced. We inspect the complete system before recommending whether one or both springs should be replaced.

Many standard springs are rated for approximately 10,000 opening-and-closing cycles, which often translates to seven to ten years for an average household. Homes that use the garage as their primary entrance can wear through springs sooner, while higher-cycle springs may provide a longer service life. Clopay’s cycle-life information

Cold weather does not necessarily ruin a healthy spring overnight, but it can expose metal fatigue that has developed over thousands of cycles. Lower temperatures, moisture, corrosion, and increased resistance from cold-stiffened components can place additional strain on an already weakened spring. A pre-winter tune-up can help identify wear before the door becomes stuck.

Torsion springs are mounted horizontally above the garage door and use torque to balance its weight. Extension springs run beside the horizontal tracks and stretch as the door closes; these systems should also have safety cables to contain the spring if it breaks. DASMA garage door safety guidance

A broken spring often leaves the door extremely heavy, crooked, or unable to rise more than a few inches, even though the opener may still run. Opener problems are more likely when the door remains properly balanced but does not respond, reverses unexpectedly, or makes noise without moving. Because forcing the opener can cause additional damage, we recommend shutting it off until the complete system can be inspected.

Usually not. If the panels, tracks, cables, and other hardware remain in good condition, replacing the spring can restore normal operation. A new door may make more sense when multiple panels are damaged, the door has extensive rust or poor insulation, or repeated repairs are beginning to outweigh the value of the existing system.

Pricing depends on the door’s weight and size, the type and number of springs, the required cycle rating, and whether cables, drums, bearings, or other hardware were damaged when the spring failed.

A proper tune-up examines the springs, cables, rollers, hinges, tracks, fasteners, door balance, opener, and safety-reversal system. Worn hardware can then be identified before it damages another component or leaves the door stuck. Manufacturers recommend regularly inspecting springs and cables while leaving spring adjustments and repairs to trained professionals. Amarr maintenance guidance
