Understanding Garage Door Springs: Types and Functions
Before you start, you must understand the type of garage door spring you’re dealing with. There are two main types of springs: torsion springs and extension springs. Each type has its characteristics and function, and the replacement process differs slightly depending on your type.
1. Torsion Springs
Torsion springs are mounted above the garage door on a horizontal metal shaft. They use torque to help lift the heavy garage door. Torsion springs wind up as the door lowers, storing energy released when the door is lifted. They are typically more durable and last longer than extension springs.
2. Extension Springs
Extension springs are located on either side of the garage door, running parallel to the horizontal tracks. These springs stretch and contract to help lift and lower the garage door. Extension springs are usually found on older garage door systems and are considered more dangerous than torsion springs because they are under more stress and tension.
Safety First: The Risks of Replacing Garage Door Springs
Garage door springs are hazardous due to the tension they’re under. If mismanaged, they can snap and cause serious injury. Before attempting to replace the spring, make sure you’re aware of the potential risks:
- Torsion Springs: Winding and unwinding torsion springs can be risky if not done properly. Always use the correct tools and take your time to avoid accidents.
- Extension Springs: These springs can whip back with force if they break while under tension, so handle them with caution.
If at any point during this guide, you feel unsure or uncomfortable, it’s best to hire a professional to handle the job. Safety is the top priority.
Gathering the Tools and Materials You’ll Need
Before starting the replacement process, gathering all the tools and materials you’ll need is important. Having everything ready will make the job easier and safer. Here’s a list of what you’ll need:
Essential Tools
- Winding bars (for torsion springs)
- Socket wrench set or an adjustable wrench
- Clamps or locking pliers
- Ladder (preferably a sturdy step ladder)
- Measuring tape
- Safety goggles and gloves
- Marker or chalk
- C-clamps (to hold the door in place)
Replacement Parts
- New garage door spring (make sure it matches the old one in size, type, and strength)
- Winding and stationary cones (for torsion springs)
- Safety cables (for extension springs, if they are not already in place)
Always double-check the specifications of the replacement spring to ensure it’s the correct match for your garage door system. Using the wrong type or size of spring can damage the door or even cause injury.
Step-by-Step Guide to Replacing a Garage Door Spring
Once you have your tools and replacement parts ready, it’s time to begin the replacement process. Follow these steps carefully to ensure accuracy and safety at each stage.
Step 1: Disconnect the Garage Door Opener
The first step is to disconnect the automatic garage door opener. This is crucial because you don’t want the motor accidentally activating while working on the springs. Unplug the opener and use the emergency release cord to disengage the door from the opener. This allows the door to move freely without being connected to the system.
Step 2: Secure the Garage Door in Place
Next, you need to secure the garage door in the open position. Clamping the door onto the track using C-clamps or locking pliers to prevent it from moving. It’s vital to ensure the door stays in place while you work on the springs to avoid accidents.
For torsion springs, the door should be fully open and secured. For extension springs, the door should be partially open to release tension. If the door is closed, the springs will be under maximum tension, making the job much more dangerous.
Step 3: Identify and Measure the Existing Spring
Before removing the old spring, it’s important to measure the current one to ensure your replacement is the correct size. Use measuring tape to measure the length, inside diameter, and wire size (gauge) of the spring.
You should also note the number of turns or coils in the spring. For torsion springs, the number of turns helps determine how much torque the spring holds, and you’ll need to match this with the new spring.
Step 4: Loosen the Unbroken Spring (for Torsion Springs)
For torsion springs, you’ll need to unwind the unbroken spring before removing it. Using the winding bars, insert one bar into the winding cone (the part of the spring wound tightly) and carefully loosen it. Always hold onto the winding bar firmly and never remove the winding bar without having the second bar inserted to take over the tension.
Turn the winding bar slowly and steadily to release the tension in the spring. Typically, you’ll need to turn it about four quarter-turns for every foot of the garage door’s height.
Once the spring is fully unwound, remove it from the shaft.
Step 5: Remove the Old Spring
For torsion springs, after unwinding the spring, loosen the set screws that hold the torsion spring to the central metal shaft. Slide the spring off the shaft, careful not to let any parts fall.
For extension springs, you’ll need to detach the safety cables (if present) and then carefully unhook the spring from the garage door track. Extension springs are often easier to remove because they don’t need to be wound down like torsion springs.
Step 6: Install the New Spring
Once the old spring is removed, it’s time to install the new one.
For torsion springs, slide the new spring onto the shaft, ensuring the stationary cone (the part that doesn’t move) faces the center bracket. Re-tighten the set screws and ensure the spring is securely in place.
For extension springs, hook the new spring onto the track and reattach the safety cables if necessary. To prevent accidents, make sure the spring is centered and that the cables are threaded correctly.
Step 7: Wind the New Torsion Spring
Winding the new torsion spring is one of the most dangerous parts of the process. Insert the winding bars into the winding cone and turn the spring, adding tension. Make sure you know the exact number of turns needed based on the garage door’s size and the spring specifications.
As you wind the spring, use your body weight to help control the tension, and always keep both hands on the winding bars. Double-check your work to ensure the spring is evenly wound and positioned correctly.
Step 8: Reconnect the Garage Door Opener
Once the new spring is installed and properly wound (or tensioned for extension springs), reconnect the garage door opener. Reattach the emergency release cord, plug the opener back in, and test the door’s operation.
Ensure the door moves smoothly up and down without any jerking or unusual noises. If the door is difficult to lift or lower, you may need to adjust the tension in the spring by adding or removing a few turns.
Step 9: Final Safety Check
Before wrapping up, conduct a final safety check to ensure everything works as it should. Test the garage door a few times to ensure it’s balanced and that the spring provides the correct amount of tension.
Listen for any unusual sounds, such as grinding or squeaking, which may indicate that the spring or other parts of the system are not aligned correctly.
Common Mistakes to Avoid During Garage Door Spring Replacement
Replacing a garage door spring is a challenging task, especially for first-timers. To help you avoid potential pitfalls, here are some common mistakes to watch out for:
1. Using the Wrong Spring Size
Using a spring that’s too strong or weak for your new garage door can cause it to malfunction. Always double-check the old spring’s measurements and ensure the new one matches exactly.
2. Skipping Safety Precautions
Never rush through safety steps, such as securing the garage door or wearing safety gear. Garage door springs can cause severe injuries if mishandled, so take every precaution seriously.
3. Not Properly Winding the Torsion Spring
Winding the torsion spring too loosely or tightly can cause operational problems with the garage door. Ensure you follow the manufacturer’s specifications for the number of turns needed for the spring to function properly.
