In this article, we will explain the function of garage door springs, how to identify a broken spring, and the critical safety measures you need to take before attempting a repair. Additionally, we will provide detailed instructions for fixing both torsion and extension springs, along with guidance on when it’s best to call a professional. By following this guide, you can reduce the risks associated with garage door spring repairs while ensuring the longevity and proper functioning of your garage door system.

2. Understanding Garage Door Springs

Garage door springs are the primary counterbalance mechanism that offsets the weight of the door, making it possible to open and close with minimal effort. Without these springs, the garage door would be extremely heavy and nearly impossible to lift manually. There are two main types of springs used in garage doors:

Torsion Springs

• Function: Torsion springs are mounted horizontally above the garage door on a metal shaft. When the door is closed, the springs are wound tightly, storing energy. When the door is opened, the stored energy is gradually released, lifting the door smoothly.

• Location: Installed on a shaft directly above the garage door.

• Durability: Typically lasts between 10,000 to 20,000 cycles (a cycle refers to one full opening and closing of the door), depending on quality and maintenance.

Extension Springs

• Function: Extension springs are mounted on either side of the garage door and stretch when the door is closed, storing tension. As the door is opened, the springs contract, helping lift the door.

• Placement: Located parallel to the horizontal tracks on both sides of the door.

• Risks: More dangerous than torsion springs due to their tendency to snap if a safety cable is not installed.

How Springs Work in a Garage Door System

Both types of springs serve the same purpose: to counterbalance the weight of the garage door. Without them, the motorized opener would struggle to lift the heavy door, potentially leading to premature motor failure. Springs also help prevent the door from slamming shut, which could pose a serious risk to people, pets, and objects in the garage.

3. Signs of a Broken Garage Door Spring

A broken garage door spring can disrupt the entire system, making it difficult or impossible to use the door. Here are some common warning signs:

• Garage door won’t open or feels unusually heavy

  • When a torsion or extension spring breaks, the door loses its counterbalancing force. This makes it significantly heavier and can cause the opener to struggle or fail completely.

• Loud snapping noise

  • Springs are under extreme tension, and when they break, they can produce a loud bang, often mistaken for something falling in the garage.

• Visible gap in the torsion spring

  • If you inspect the torsion spring above the garage door, a broken one will often have a 2-4 inch gap where the coil has snapped.

• Uneven or jerky movement of the door

  • If one extension spring breaks, the door may open unevenly or become misaligned, putting additional strain on the remaining spring and door components.

• Door slams shut suddenly

  • A failing spring may not be able to hold the door’s weight properly, causing it to drop suddenly, which can be extremely dangerous.

4. Safety Precautions Before Repair

Dangers of Handling Garage Door Springs

Garage door springs, whether torsion or extension, are under extreme tension. A broken or improperly handled spring can cause severe injury or property damage. When a torsion spring breaks, it can snap back with enough force to shatter nearby objects or injure anyone in its path. Extension springs, if improperly secured, may even launch themselves across the garage.

Common mistakes made by DIYers include underestimating the tension in the springs and attempting to work without proper tools. Attempting to repair a spring without following the correct procedure or safety guidelines can lead to dangerous outcomes. For instance, improper use of winding bars can cause the spring to unwind too quickly, resulting in an uncontrollable release of tension.

Essential Safety Gear and Tools

Before attempting any repair, it’s crucial to equip yourself with the proper safety gear and tools to minimize the risk of injury:

• Safety glasses and gloves: These will protect your eyes from flying debris and your hands from sharp edges or sudden movements.

• Sturdy clothing: Wear long sleeves and pants to protect your skin from injury.

• Winding bars, clamps, and vice grips: Winding bars are essential for releasing and tightening the tension in torsion springs. Clamps help secure the door in place to prevent accidental movement, and vice grips are useful for keeping springs in place during repairs.

Disengaging the Opener and Securing the Door

Before starting the repair, make sure to disengage the automatic opener. This prevents any accidental activation of the opener while you’re working on the springs. To disengage the opener, locate the manual release cord, which is typically a red cord hanging from the opener. Pull this cord to disengage the door from the opener mechanism.

It’s also crucial to manually secure the door. Once the opener is disengaged, the door should be supported to prevent it from suddenly falling. You can secure the door by using clamps or locking it in place with a sturdy object, such as a wood block or a safety cable.

5. Step-by-Step Guide to Fixing a Broken Torsion Spring

Step 1: Gather the Right Replacement Spring

Before starting the repair, it’s important to measure the existing spring correctly. Key measurements include the spring’s length, wire size, and inner diameter. These measurements will help you select a suitable replacement that matches your door’s weight and size.

Step 2: Release Tension from the Old Spring

Releasing the tension from a torsion spring requires caution. Use winding bars to slowly release tension, turning them in a controlled manner. Avoid using excessive force to prevent the spring from unwinding too quickly, which could cause it to break or damage nearby parts.

Step 3: Removing the Broken Spring

Once tension is released, carefully detach the broken spring from the center bracket and drums. It’s important to support the spring as you remove it to prevent it from snapping back. Use vice grips to keep the spring from shifting as you work.

Step 4: Installing the New Spring

Position the new torsion spring properly above the door. Ensure that it is centered and aligned with the center bracket and drums. Secure the spring using the appropriate hardware, making sure all connections are tight and secure.

Step 5: Rewinding the Spring with Correct Tension

Using the winding bars, rewind the spring to the required tension. The number of turns will depend on the door’s weight. Typically, you’ll need to refer to the manufacturer’s specifications or use a general guide to determine the exact number of turns for your door size.

Step 6: Testing the Door for Proper Balance

Once the spring is rewound and secured, it’s time to test the door’s balance. Open and close the door manually to ensure it moves smoothly. If the door feels uneven or slams shut, you may need to adjust the tension in the spring or check for other issues in the system.

6. Step-by-Step Guide to Fixing a Broken Extension Spring

Step 1: Choosing the Right Replacement Spring

Measure the existing extension spring carefully before purchasing a replacement. You’ll need to know the spring’s length, diameter, and load capacity to choose an appropriate replacement.

Step 2: Removing the Damaged Spring

Start by disconnecting the spring from its attachment points on both sides of the garage door. Be sure to support the spring as you remove it to prevent it from snapping back.

Step 3: Installing the New Extension Spring

Position the new extension spring in place. Attach one end to the door’s rear track and the other to the pulley or the attachment point on the door. Ensure the spring is properly aligned with the track and is not twisted.

Step 4: Adjusting Tension and Testing the Door

Once the new spring is in place, adjust the tension. Extension springs should have equal tension on both sides of the door for smooth operation. After adjusting, test the door’s operation by opening and closing it manually. If the door operates unevenly or gets stuck, recheck the tension and make necessary adjustments.

7. When to Call a Professional

While fixing a broken garage door spring can seem like a manageable DIY task, certain situations make it too dangerous for homeowners to attempt the repair themselves. Here are some critical scenarios when it’s best to call a professional:

• Excessive Spring Tension: Springs operate under extreme tension. If you are unsure about releasing the tension correctly, it’s safer to leave the task to a professional. A mishandled spring can release unexpectedly and cause severe injury.

• Multiple Broken Springs: If both torsion and extension springs are broken, or if the springs are unusually worn out, the complexity of the repair increases. A professional will ensure the proper balance and alignment of the new springs.

• Damaged Garage Door System: In some cases, a broken spring may indicate underlying issues such as damaged tracks, cables, or pulleys. Professionals are equipped to address not only the spring replacement but also to check for other mechanical issues.

• Lack of Proper Tools and Experience: DIY repairs require specialized tools, such as winding bars and spring clamps, as well as experience to handle them properly. If you lack the tools or experience, attempting the repair may cause more damage to the door or result in an unsafe condition.

• When Time is a Factor: If you rely on your garage door regularly and need the repair completed quickly and safely, calling a professional is the most efficient option.

Cost vs. Risk

While hiring a professional repair service may seem like a more expensive option, the cost of repairs resulting from an improperly done DIY repair, or the potential for injury, outweighs the cost savings. A professional ensures that the repair is done safely and correctly the first time, providing long-term peace of mind and preventing future issues.

8. Preventive Maintenance to Extend Spring Lifespan

Regular maintenance can significantly extend the life of your garage door springs, reducing the likelihood of premature failure and expensive repairs. Follow these simple steps to ensure that your springs remain in good working condition:

• Regular Lubrication: Applying a silicone-based lubricant to the springs every six months helps reduce friction and wear. This simple step can prevent rust and keep the springs operating smoothly.

• Inspection for Wear and Tear: Periodically inspect the springs for visible signs of wear, such as cracks, rust, or stretching. If you notice any damage, address it immediately before it leads to a complete failure.

• Door Balancing: If the garage door is unbalanced, it puts extra strain on the springs, causing them to wear out faster. To maintain proper balance, disconnect the opener and manually lift the door. If it doesn’t stay in place or feels heavy on one side, it may need adjustment.

• Replacing Both Springs at the Same Time: Garage doors typically have two springs for even weight distribution. Replacing only one spring may result in imbalance and cause the new spring to wear out faster. Replacing both springs at the same time can improve door balance and extend the life of the entire system.

By maintaining your garage door springs regularly, you can avoid costly repairs, increase the safety of your garage, and extend the overall lifespan of the door system.

9. Conclusion

Fixing a broken garage door spring is a critical repair that requires careful attention to safety and proper technique. Remember to prioritize safety at all times. Always wear protective gear and use the right tools, and when in doubt, don’t hesitate to call a professional.

For homeowners considering the repair, assess whether you have the necessary tools, experience, and knowledge to safely complete the task. If you are unsure, it’s better to invest in professional services to ensure the job is done correctly and without risk.
