Stop Guessing! Here’s Exactly How Many Turns on a Garage Door Spring You Should Apply!

It’s late, and you’re closing up for the night when you notice your garage door isn’t behaving quite right. Maybe it’s struggling to open or slamming shut too quickly. These are often signs that your garage door springs aren’t tensioned correctly. While it might seem like a small detail, the number of turns on your garage door spring is crucial to ensuring smooth operation and preventing potentially dangerous situations.

Properly tensioned springs balance the weight of your garage door, making it easier to lift and lower without putting unnecessary strain on your opener. Too few turns and your door might not stay open; too many, and it could fly up unexpectedly. Getting the balance just right is key to a well-functioning garage door.

Understanding the Right Number of Turns for Garage Door Springs

Garage door springs are the unsung heroes of your garage door system, providing the tension and support needed to lift and lower the door smoothly. But how many turns should you apply to these springs? It’s a common question with a critical answer—getting it right is key to your door’s performance and safety.

The Importance of Properly Tensioned Garage Door Springs

Getting the correct number of turns on your garage door spring is more than just a technical detail; it’s essential for the smooth operation of your door. The tension in these springs counterbalances the door’s weight, making it easier to open and close.

Why Does It Matter?

If your springs are wound with too few turns, your door might not stay open, and the opener will have to work harder. On the flip side, too many turns can make the door fly up too quickly, posing a safety risk. An improperly tensioned spring can also lead to faster wear and tear, shortening the lifespan of your garage door components.

What Could Go Wrong?

  • Door Imbalance: When the tension in your garage door springs isn’t set correctly, it can cause the door to hang unevenly. This imbalance looks unsightly and places uneven stress on the door’s hardware, such as the hinges, rollers, and tracks. Over time, this added strain can cause these components to wear out prematurely or even break, leading to costly repairs or replacements. An imbalanced door might also scrape against the frame or the ground, causing further damage to the door itself.

  • Strain on the Opener: A garage door opener is designed to work in tandem with properly tensioned springs. If the springs are too loose, the opener has to work much harder to lift the heavy door, leading to excessive strain on the motor and gears. This increased workload can cause the opener to overheat, wear out faster, and eventually fail, requiring an expensive replacement. In severe cases, the opener might not be able to lift the door at all.

  • Safety Hazards: Over-tightening garage door springs is particularly dangerous. Springs under too much tension are more prone to snapping unexpectedly, which can cause serious injury or damage. When a spring breaks, it releases a tremendous amount of stored energy, potentially sending broken pieces flying with enough force to cause injury or damage to nearby objects. Additionally, a snapped spring can render the door inoperable, leaving it stuck in place or even causing it to crash suddenly, which poses a significant safety risk, especially if someone is near the door.

How to Calculate the Correct Number of Turns on Your Garage Door Spring

Properly winding your garage door springs is a precise task that plays a crucial role in the overall functionality of your garage door. Before you begin, you must understand the type of springs you’re dealing with and how they interact with your garage door’s weight and movement.

Types of Garage Door Springs

Torsion Springs: The most common type found in modern garage doors, typically mounted horizontally above the door. They work by twisting as the door is lowered, creating tension that helps balance the door’s weight. This twisting action stores energy in the spring, which is released when the door is raised.

Extension Springs: Mounted on either side of the door, extension springs stretch and contract as the door moves. They extend when the door is lowered, storing energy used to lift it when it’s opened. Although less common than torsion springs, they are still widely used, particularly in older garage doors.

Steps to Determine the Right Number of Turns

1. Identify Your Spring Type

Start by determining whether your garage door uses torsion springs or extension springs. This distinction is important because each spring type has a different method for calculating the number of turns or stretches needed.

2. Measure the Door’s Height

The height of your garage door is a critical factor in determining how many turns your springs will need. For example, a standard 7-foot door typically requires 30 to 36 quarter turns for each torsion spring. If your door is taller, it may require more turns, while a shorter door may need fewer.

3. Count the Existing Turns 

If you’re adjusting a spring that’s already installed, start by counting the number of turns currently on the spring. This gives you a baseline to understand how much adjustment is necessary. You can count by marking the spring with a piece of tape or chalk and noting how many times the mark rotates as you unwind the spring.

4. Consult Manufacturer Guidelines

Manufacturer recommendations are your best reference for determining the correct number of turns for your specific springs. This information is usually provided with the springs when they are new. Still, if you don’t have it, you can often find the guidelines on the manufacturer’s website or by contacting customer service.

Tips for Accuracy

Use a Marker: Before you start winding, mark the spring with chalk, tape, or a permanent marker. This will help you keep track of the number of turns as you work. Make sure to mark the spring in a visible spot so you can count the rotations easily.

Work Slowly: Patience is key when adjusting garage door springs. Wind the spring slowly and deliberately to ensure that each turn is precise and you don’t over-tighten. Moving too quickly increases the risk of making a mistake, which could lead to improper tension and the problems that come with it.

By following these steps and tips, you can ensure that your garage door springs are properly wound. This will help maintain a balanced door and extend the life of your garage door system. If you feel unsure or uncomfortable, it’s always wise to consult a professional garage door repair service to avoid any potential risks.

Safety First: Precautions When Adjusting Garage Door Springs

Garage door springs are under significant tension, making them potentially dangerous to adjust if you’re not careful. Here’s how to stay safe:

Essential Safety Gear

  • Gloves: Protect your hands from sharp edges and provide a better grip on the tools.

  • Safety Glasses: Prevent debris from getting into your eyes.

  • Sturdy Ladder: Ensure your ladder is stable and tall enough to give you easy access to the springs.

Tools You’ll Need

  • Winding Bars: These are specialized rods designed to fit into the winding cone of the torsion spring.

  • C-Clamp or Locking Pliers: Use these to secure the garage door, preventing it from moving while you work.

  • Wrench Set: You’ll need these to loosen or tighten the set screws on the winding cone.

Step-by-Step Safety Guide

  1. Secure the Door: Clamp the garage door to the track to prevent it from moving while you adjust the springs.

  2. Release the Tension Slowly: Never rush the process. Release tension from the spring slowly to avoid accidents.

  3. Check Your Work: After adjusting the spring, test the door manually to ensure it operates smoothly before reconnecting the opener.

When to Call a Professional

If you’re unsure about handling the springs or if your garage door has multiple springs, it’s safer to hire a professional. The cost of professional help is worth avoiding the risks involved with DIY adjustments.

Common Issues from Incorrect Spring Tension and How to Fix Them

Even a slight miscalculation in winding the springs can lead to noticeable problems with your garage door. Here’s what to watch out for and how to address these issues.

Signs of Incorrect Spring Tension

  • Door Won’t Stay Open: If the door drifts closed after opening, the springs may need more turns.

  • Door Slams Shut: This is a sign that the springs are over-wound, causing the door to close too quickly.

  • Uneven Door Movement: A jerky or uneven motion usually means the tension isn’t balanced correctly across the springs.

Troubleshooting Tips

  • Recheck Your Turns: If the door isn’t operating smoothly, recount the number of turns on each spring and adjust as necessary.

  • Inspect the Springs: Look for any signs of wear, such as gaps between the coils or rust. Damaged springs should be replaced immediately.

  • Balance Test: Disconnect the opener and manually lift the door halfway. If it stays in place, the springs are likely balanced correctly. If it moves, further adjustment is needed.

When to Replace the Springs

If your garage door springs are old or show signs of significant wear, it might be time to replace them rather than just adjusting. Regular inspection can help you avoid unexpected failures.
