How much tension on garage door springs?

Welcome to the MM Garage Door Repair Utah blog! As your local garage door experts, we often get asked about the inner workings of your garage door system. One of the most common questions we receive revolves around garage door springs and, specifically, the amount of tension they should have. Understanding this tension is crucial for both the safe and efficient operation of your garage door. So, let’s dive into the world of garage door spring tension!

Understanding Garage Door Spring Tension

Garage door springs are the unsung heroes responsible for lifting and lowering your heavy garage door. They work by storing mechanical energy when the door is closed and releasing it when the door opens. This counterbalance system makes it seem effortless to lift what is often a very heavy door. The tension in these springs is what provides the necessary force to accomplish this task. Without the correct tension, your garage door can become difficult to operate, pose a safety hazard, or even fail completely.

Why is Correct Spring Tension Important

Maintaining the correct spring tension is paramount for several reasons:

• Safety: Incorrect tension can cause the door to slam shut unexpectedly, posing a serious risk of injury.
• Ease of Use: Proper tension ensures the door opens and closes smoothly and with minimal effort.
• Longevity: Balanced tension reduces strain on the garage door opener and other components, extending their lifespan.
• Proper Function: The door will stay open at the desired height and close completely without gaps.

Determining the Correct Tension

Determining the correct tension for your garage door springs isn’t an exact science, but there are some guidelines to follow. The ideal tension depends on several factors, including the weight and size of your garage door, the type of springs used (torsion or extension), and the spring’s wire size and length.

Important Safety Note: Working with garage door springs can be extremely dangerous. The springs are under high tension, and improper handling can lead to serious injury or even death. If you are not comfortable working with springs, we strongly recommend contacting a qualified garage door technician like those at MM Garage Door Repair Utah. We have the tools and expertise to safely adjust your springs.

Torsion Springs vs Extension Springs

Before we delve into tension adjustment, it’s crucial to identify the type of springs your garage door uses:

Torsion Springs: These are mounted horizontally above the garage door opening. They twist to create tension. The tension is adjusted by loosening set screws on the spring and winding or unwinding the spring using winding bars.

Extension Springs: These are located on either side of the garage door, running parallel to the horizontal tracks. They stretch to create tension. Tension is adjusted by moving the S-hooks that connect the springs to the track, or by adding or removing links from the safety cable.

Steps to Check and Adjust Torsion Spring Tension (Proceed with extreme caution!)

Disclaimer: These steps are for informational purposes only. We highly recommend that only qualified technicians perform these adjustments.

1. Safety First: Disconnect the garage door opener from the power source.
2. Secure the Door: Use clamps or locking pliers on the track just above the rollers to prevent the door from moving during the adjustment.
3. Loosen Set Screws: Carefully loosen the set screws on the spring using the appropriate wrench.
4. Adjust Tension: Insert winding bars into the winding cone holes and wind or unwind the spring in small increments. Winding increases tension, unwinding decreases it. A general rule of thumb is to wind the spring one quarter turn for every foot of door height. For example, a 7-foot door would require approximately 28 quarter turns (7 feet x 4 quarter turns/foot).
5. Tighten Set Screws: Once the desired tension is achieved, tighten the set screws securely.
6. Test the Door: Remove the clamps and manually lift the door halfway. It should stay in place. If it drifts up or down, further adjustment is needed.
7. Reconnect Opener: Reconnect the garage door opener to the power source.

Steps to Check and Adjust Extension Spring Tension (Proceed with extreme caution!)

Disclaimer: These steps are for informational purposes only. We highly recommend that only qualified technicians perform these adjustments.

1. Safety First: Disconnect the garage door opener from the power source.
2. Secure the Door: Use clamps or locking pliers on the track just above the rollers to prevent the door from moving during the adjustment.
3. Inspect Springs: Carefully inspect the springs for any signs of wear or damage. Replace damaged springs immediately.
4. Adjust Tension: Adjust the tension by moving the S-hooks that connect the springs to the track. Moving the S-hook to a higher link increases tension, while moving it to a lower link decreases tension.
5. Test the Door: Manually lift the door halfway. It should stay in place. If it drifts up or down, further adjustment is needed.
6. Reconnect Opener: Reconnect the garage door opener to the power source.

Here are some telltale signs that your garage door springs may need adjustment:

• The door is difficult to open or close.
• The door slams shut or opens too quickly.
• The door doesn’t stay open at the desired height.
• The door is uneven or lopsided when opening or closing.
• You hear unusual noises coming from the springs.
