How do I know if my tension spring is broken?

Share this blog:

A tension spring is crucial in various mechanical systems, providing the necessary tension and support to ensure proper functioning. Whether it’s in a garage door, a trampoline, or a screen door, a broken tension spring can cause significant issues and compromise the overall performance. In this article, we will explore the signs and symptoms that indicate a broken tension spring, enabling you to identify and address the problem promptly.

Understanding Tension Springs

Tension springs are typically made of high-quality steel and are designed to stretch and recoil repeatedly under load. They store mechanical energy when stretched and release it when recoiled, providing the necessary force to counterbalance or assist the movement of various mechanical systems. These springs are commonly used in garage doors, trampolines, screen doors, and many other applications where tension is required.

Tension springs have a specific anatomy that consists of tightly wound coils. These coils are designed to stretch and return to their original shape without deformation. The high-quality steel construction of tension springs ensures durability and resilience under heavy loads and repeated use.

Signs of a Broken Tension Spring

  1. Difficulty in Opening or Closing: One of the most apparent signs of a broken tension spring is the difficulty in opening or closing the system it is part of. For instance, struggling to open or close your garage door smoothly may indicate a broken tension spring. Similarly, a broken tension spring could be the culprit if a trampoline feels unusually stiff or fails to bounce properly. The lack of tension in the spring hinders the system’s smooth operation, causing resistance and making it harder to use.
  2. Uneven Movement: Another common indicator of a broken tension spring is uneven movement. When a tension spring breaks, it can lead to an imbalance in the system it supports. This imbalance often results in crooked or jerky movements, making it evident that there is a problem with the tension spring. For example, a garage door may tilt to one side instead of moving evenly, or a trampoline may have one side higher than the other when used.
  3. Visible Damage: In some cases, a broken tension spring may be visually apparent. Inspect the tension spring closely; it is likely broken if you notice any signs of wear, deformation, or physical damage. Look for signs such as gaps, cracks, or missing coils, as these are clear indicators of a broken tension spring. Additionally, rust or corrosion on the spring can weaken its structure and lead to breakage.
  4. Loud Noise: A broken tension spring can also produce distinctive sounds, such as a loud bang or snap when it breaks. If you hear any unusual noises when operating the system, it is advisable to investigate the source, as it may indicate a broken tension spring. The sudden release of tension can create a loud noise that is easily noticeable. Pay attention to any unexpected sounds when you open or close the system, as they can be a sign of a broken tension spring.
  5. Lack of Tension: Tension springs are designed to provide resistance and tension. If you notice a significant reduction in the tension or resistance when operating the system, it could be due to a broken spring. For example, if your screen door fails to close smoothly and lacks the usual resistance, it might be time to inspect the tension spring. The lack of tension indicates that the spring is no longer functioning properly and needs attention.

Steps to Confirm a Broken Tension Spring

While the above signs and symptoms can help you identify a broken tension spring, it is essential to follow these steps for a more accurate confirmation:

  1. Visual Inspection: Begin by visually inspecting the tension spring for any visible signs of damage or wear. Look for gaps, cracks, or missing coils, and ensure that the spring appears intact and undamaged. Take note of any rust or corrosion as well, as it can weaken the spring’s structure.
  2. Test the Movement: Perform a thorough test of the system’s movement that relies on the tension spring. Pay close attention to any uneven or jerky movements, stiffness, or difficulty in opening or closing. These issues often indicate a broken tension spring. Take note of any tilting, bouncing irregularities, or resistance that is not consistent with the normal operation of the system.
  3. Listen for Unusual Sounds: Operate the system and listen for any unusual noises, such as loud bangs or snaps that may accompany a broken tension spring. If you detect any such noises, it is highly likely that the tension spring is broken. Make sure to distinguish these sounds from other normal operational sounds of the system.
  4. Professional Inspection: If you are unsure or unable to confirm the presence of a broken tension spring through visual inspection and testing, it is advisable to seek professional assistance. A trained technician can accurately diagnose the problem and provide appropriate solutions. They have the expertise and tools to identify and address issues related to tension springs effectively.

Importance of Addressing a Broken Tension Spring

Ignoring or neglecting a broken tension spring can lead to various issues, including:

  • Safety hazards: A broken tension spring can cause the system to malfunction, leading to potential accidents and injuries. For instance, a garage door with a broken tension spring may unexpectedly slam shut, posing a threat to anyone nearby. Promptly addressing the issue ensures the safety of individuals using the system.
  • Further damage: A broken tension spring can place excessive stress on other components of the system, leading to their premature wear and tear. By addressing the issue promptly, you can prevent further damage and expensive repairs. The malfunctioning tension spring can cause strain on other parts, which can lead to their failure or damage. Fixing or replacing the broken tension spring avoids unnecessary expenses and prolongs the life of the system.
  • Inconvenience: Systems relying on tension springs, such as garage doors or trampolines, may become unusable or inconvenient to operate with a broken tension spring. Repairing or replacing the tension spring ensures these systems’ smooth functioning and convenience. A broken tension spring can render the system inoperable or significantly affect its performance, causing inconvenience to the users. Addressing the issue allows for the uninterrupted use of the system.


In conclusion, identifying a broken tension spring is crucial to maintain various mechanical systems’ proper functioning and safety. By recognizing the signs and symptoms outlined in this article and following the necessary steps for confirmation, you can address the issue promptly. Remember, if you are uncertain or unable to confirm the presence of a broken tension spring, it is always advisable to seek professional help to ensure accurate diagnosis and appropriate solutions. Taking prompt action not only ensures the safety of individuals but also prevents further damage and inconvenience.
