How to Check Garage Door Spring Tension Safely: Fix Common Issues
Is your garage door acting up? Maybe it’s slamming shut, refusing to open fully, or just feels heavier than usual. These can all be signs your garage door spring tension is off. As a homeowner, it’s smart to know when something’s not right, but it can be tricky figuring out how to check garage door spring tension safely.
At Level Up Garage Door, we know how frustrating a malfunctioning garage door can be in your daily routine. Let’s break this down so you can better understand your garage door’s spring system and when to make adjustments – or call in a professional.
What You Should Know About Your Garage Door Spring
There are two main types of garage door springs:
- Torsion springs: These are mounted horizontally above the garage door on the wall. They twist (or torque) to create tension.
- Extension springs: Typically mounted on each side of the door parallel to the door tracks, they stretch when the door is closed.
Both require just the right tension to keep the door opening and closing correctly. Incorrect spring tension can lead to unbalance, excessive noise, or even injury if a spring breaks.
Signs Your Garage Door Spring Tension Needs Attention
So how do you know if your garage door spring tension needs adjusting? Here’s what to look for:
- The door feels heavy when lifted manually.
- The door opens too quickly or slams shut.
- The door moves unevenly or looks off-balance.
- The door doesn’t stay open on its own.
- The garage door opener is straining or can’t lift the door.
These are all signs that the tension in the springs might be off. When spring tension is too tight or too loose, it puts stress on the garage door opener and other components, such as the cable, pulleys, and rollers.
How to Check Garage Door Spring Tension
If you’re asking, “How do I know if my garage door spring tension is right?”, follow these steps carefully. Always wear safety gear and keep children and pets away during this process.
Step 1: Disconnect the Opener
Start with safety. Use the release cord (a red cord hanging from your garage door opener) to disconnect the opener and switch to manual operation.
Step 2: Open the Door Halfway
Manually open the door halfway and let go. This simple test reveals a lot about your spring tension.
- If the door stays in place, your spring tension is likely good.
- If the door falls, increase the spring tension.
- If the door shoots up, the tension is too high.
This is sometimes referred to as the test the door method.
Step 3: Check for Unbalance
If your garage door looks crooked or moves unevenly, the springs may be worn or adjusted incorrectly. Unbalance can put extra strain on the entire system and needs fast attention.
Step 4: Visual Inspection
Inspect both the torsion spring and extension springs for signs of wear, damage, or rust. Check for loose set screws, worn rollers, or stretched-out safety cables. If springs have become deformed or frayed, it’s time to call a professional.
Spring Adjustments: DIY or Leave It to a Pro?
Garage door spring adjustments can be extremely dangerous. The springs are under a lot of tension (in terms of physics and mechanics), and one wrong move can cause serious injury.
That’s why we typically recommend a professional garage door repair service if:
- You lack the proper tools (like a winding bar, c-clamp, or socket wrench)
- You’re unsure what kind of spring you have
- You suspect the spring is close to breaking
Still, for experienced DIYers, here’s a simplified overview.
How to Adjust a Garage Door Spring (for DIYers Only)
For Torsion Springs:
- Wear safety equipment – goggles, gloves, and long sleeves are a must.
- Clamp the door to keep it from moving.
- Insert a winding bar into the winding cone attached to the center shaft of the spring.
- Hold the first bar firmly and insert the second into the next hole on the cone.
- Carefully unwind or wind according to the issue:
- If the door feels heavy, tighten (wind) the spring clockwise to increase tension.
- If the door opens too quickly, unwind to reduce tension.
- Tighten the set screws and check the balance again.
For Extension Springs:
- Disconnect the opener and open the door fully so there’s little tension.
- Use a s-hook to move the hook on the pulley to a different hole on the bracket.
- To increase tension, stretch the spring by shortening the cable connection.
- Lower the door and retest.
Important: Always conduct a safety recheck after adjustments by lifting the door halfway again.
Dangers of Improper Spring Tension
Improper tension can:
- Prevent the door from opening or closing correctly.
- Cause the door to become unbalanced and place excess strain on the garage door opener.
- Lead to a dangerous door from falling unexpectedly.
- Result in loud noises or a door suddenly jerking.
It’s not just about performance – it’s about safety too.
When to Call a Professional Garage Door Technician
If any of the following apply, it’s time to call a professional service tech:
- You hear a loud “bang” (a spring breaks).
- You’re unsure what adjustments to make.
- The door needs multiple adjustments frequently.
