How to Replace a Broken Garage Door Spring A Complete Guideline

Got a broken garage door spring causing you trouble? Wondering how to replace a broken garage door spring? Well, you’ve come to the right place! We get the frustration of dealing with a faulty garage door. But don’t worry, we’ve got your back!

A broken garage door spring can throw a wrench into your daily routine. It’s not just the inconvenience of the door not opening or closing smoothly; it’s the worry of potential safety hazards that can leave you feeling overwhelmed. 

In this blog, we’ll take you on a journey through the process of replacing a broken garage door spring.

Reasons Why Garage Door Springs Break

Before learning how to fix a broken garage door spring, understanding the reasons behind its breakage is essential.

Wear and Tear 

Like any mechanical component, garage door springs experience wear and tear over time. Constant use, especially in busy households, can lead to fatigue and eventually cause the spring to break.


Springs have a lifespan, and as they get older, they become more susceptible to breaking. Even with proper maintenance, springs will eventually wear out and need replacement.

Rust and Corrosion 

Moisture and exposure to the elements can lead to rust and corrosion on the springs. This weakens the metal and makes it more prone to breaking.

Poor Maintenance 

Lack of regular maintenance, such as lubrication and inspection, can contribute to spring failure. Small issues left unattended can lead to bigger problems.

Incorrect Springs 

Using the wrong type or size of springs for your garage door can put excessive stress on them, causing premature failure.

Sudden Impact 

A strong impact, like hitting the garage door with a vehicle or heavy object, can cause immediate damage to the springs.

Temperature Changes 

Extreme temperature fluctuations can affect the spring’s elasticity and durability, which leads to eventual breakage.

DIY Repairs

Attempting to adjust or repair springs without proper knowledge and tools can cause damage and increase the risk of breaking.

Ways to Identify a Broken Garage Door Spring 

Ways to Identify a Broken Garage Door Spring

Identifying a broken garage door spring is crucial for timely repairs. Here are some easy-to-spot signs:

The door Won’t Open 

If your garage door refuses to open or only rises a few inches, it could be due to a broken spring.

Loud Bang 

A loud bang or snapping sound when operating the door often indicates a broken spring.

Crooked or Uneven Door 

A garage door that appears crooked or uneven when opening or closing may have a broken spring on one side.

Gaps in Spring 

If you notice a noticeable gap in the spring or see a visibly broken spring, it’s time for a replacement.

Difficulty Lifting Manually 

Attempting to lift the garage door manually might feel excessively heavy due to a broken spring’s lack of support.

Steps on How to Replace a Broken Garage Door Spring

Garage door springs are under a lot of tension, so when one breaks, it can be dangerous to try to fix it yourself. However, if you’re comfortable with DIY projects and have the right tools, it is possible to replace a broken garage door spring.

Here are the steps involved in how to replace broken garage door springs.

Step 1: Safety First

Before you dive into fixing your garage door spring, let’s talk safety! Those springs are under a lot of tension and can be dangerous. So, first things first:

  • Put on protective goggles and gloves to protect your eyes and hands.
  • Keep pets and kids away from the work area – safety first for everyone!
  • Have a helper on hand to help you if needed.
  • Be careful not to let the springs snap back.
  • Only proceed if you feel comfortable doing the repair. If you’re unsure, it’s best to call a pro for the garage door broken spring replacement.

Step 2: Identify the Type of Spring

Identify the Type of Spring

Next, figure out what type of garage door spring you have. Knowing the type will help you with the replacement process. There are two common types:

Torsion Springs 

Torsion springs are special coiled springs used in garage doors to make them open and close smoothly. Instead of stretching out like a regular spring, these springs twist or coil up tightly when you operate the garage door.

You’ll find these springs above the garage door, mounted on a metal rod called the torsion tube. When you open the garage door, the torsion springs store energy by winding up tightly. Then, when you close the door, the stored energy gets released, helping the door go up and down easily.

Torsion springs come in different sizes and strengths to match the weight and size of various garage doors. They are crucial for making the garage door work correctly. However, because they have a lot of tension, it’s essential to be careful when handling them. 

Extension Springs 

Extension springs are another type of coiled springs used in garage doors to help them open and close smoothly. These springs work by extending or stretching when you operate the garage door.

Unlike torsion springs that are mounted above the door, extension springs are found on both sides of the door, running parallel to the tracks. When you open the garage door, these springs stretch out and store energy. Then, when you close the door, the stored energy helps the door go down gently.

Extension springs also come in various sizes to match different garage door weights. They work together to balance the door and make sure it moves smoothly. Just like with torsion springs, you should be cautious when dealing with extension springs as they are under tension. 

Step 3: Get the Right Tools

Grab the tools you’ll need for the job:

  • C-clamps or locking pliers
  • Winding bars (you’ll use these for torsion springs)
  • Socket wrench and adjustable wrench
  • Vice grips
  • And, of course, the new garage door spring that matches the old one.

Step 4: Release Tension from the Old Spring

For Torsion Springs

  • Use those C-clamps or locking pliers to hold the garage door in place.
  • Put the winding bars into the winding cone of the broken spring.
  • Carefully unwind the old spring with the winding bars. Watch out for that tension!
  • Once it’s all unwound, take out the old spring from its brackets.

For Extension Springs

  • Open the garage door all the way to release tension from the springs.
  • Keep it secure with the vice grips.
  • Disconnect the safety cable from the pulley system and remove the broken spring.

Step 5: Install the New Spring

For torsion springs

Alright, it’s time to install the new spring for torsion springs. Follow these simple steps:

  • Slide the New Spring: Gently slide the new spring onto the torsion tube. Make sure it fits snugly into the brackets.
  • Wind the Spring: Grab those winding bars again and start winding the new spring. Remember, this time, wind it in the opposite direction from the old one.
  • Reattach the Garage Door: Once the new spring is securely wound, reattach the garage door to the opener. Make sure everything is properly aligned.

For extension springs

Let’s install the new extension spring. Here’s how:

  • Put the New Spring in Place: Take the new spring and carefully put it on the garage door track. Please make sure it’s positioned correctly.
  • Reconnect the Safety Cable: Next, connect the safety cable back to the pulley system. This will keep everything secure and safe.
  • Release the Door Gently: Now, it’s time to remove the vice grips. Be cautious and gently let the garage door down, ensuring it moves smoothly.

Step 6: Test and Adjust

With the new spring in place, test your garage door. Open and close it slowly to check for any issues. If something feels off, adjust the spring tension until the door operates smoothly.

Additional Tips

Here are some additional tips for replacing a broken spring:

  • Make sure that you purchase the correct size and type of springs for your garage door.
  • Lubricate the springs before you install them. This will help to extend their life.
  • Inspect the springs regularly for wear and tear. If you notice any damage, replace the springs immediately.
