How to replace coil springs on a garage door?

Welcome to the MM Garage Door Repair Utah blog! As your trusted local garage door experts, we’re dedicated to providing you with the knowledge and solutions you need to keep your garage door operating safely and efficiently. Today, we’re tackling a crucial topic: replacing garage door coil springs. This is a repair that many homeowners consider tackling themselves, but it’s essential to understand the risks involved. Garage door springs are under immense tension, and improper handling can lead to serious injury. This guide will provide you with the information you need to make an informed decision about whether to DIY or call in the professionals at MM Garage Door Repair Utah.

Understanding Garage Door Springs

Garage door springs are the unsung heroes of your garage door system. They provide the counterbalance needed to lift and lower your heavy garage door with relative ease. There are two main types of garage door springs: torsion springs and extension springs. Torsion springs are mounted above the garage door opening, while extension springs are located along the horizontal tracks on either side of the door. This guide primarily focuses on torsion spring replacement, as it’s the more common type in modern garage door systems. However, the safety precautions apply to both types.

Safety First A Critical Warning

Before we dive into the steps, let’s emphasize the importance of safety. Garage door springs are under extreme tension and can cause serious injury or even death if mishandled. If you are not comfortable working with high-tension springs, we strongly recommend contacting a qualified garage door technician like those at MM Garage Door Repair Utah. This is not a job to take lightly. Always wear safety glasses and gloves. Never attempt to release or adjust the spring tension without the proper tools and knowledge.

Tools and Materials You’ll Need

If you decide to proceed with replacing your garage door springs yourself, you’ll need the following tools and materials:

• New garage door springs (matching the exact specifications of your old springs)
• Winding bars (correct size for your springs)
• Safety glasses
• Gloves
• Adjustable wrench
• Vice grips
• Ladder
• Marker or tape

Important: Make sure you purchase the correct replacement springs. Measure the length, wire gauge, and inside diameter of your old springs. These measurements are crucial for ensuring proper operation and safety.

Step-by-Step Guide to Replacing Torsion Springs

Step 1: Secure the Garage Door

Before you begin, ensure the garage door is completely closed. Clamp the garage door tracks just above the rollers with vice grips to prevent the door from accidentally opening during the spring replacement process. This is a critical safety measure.

Step 2: Loosen the Old Springs

Insert one winding bar into the winding cone of the spring. Loosen the set screws on the winding cone. With the winding bar securely in place, carefully loosen the spring by inserting the second winding bar above the first and slowly releasing the tension. Alternate between the two winding bars, gradually unwinding the spring until all tension is released. This process requires patience and control. Mark the shaft with tape to know how many turns to release.

Step 3: Remove the Old Springs

Once the spring is fully unwound, carefully remove the winding bars. Loosen the set screws on the stationary cone (the cone attached to the center bracket). Slide the spring off the torsion tube. Repeat this process for the other spring if you are replacing both (which is highly recommended).

Step 4: Install the New Springs

Slide the new spring onto the torsion tube, ensuring it’s oriented correctly (the winding cone should be on the same side as the winding cone of the old spring). Secure the stationary cone to the center bracket by tightening the set screws.

Step 5: Wind the New Springs

This is the most critical and potentially dangerous step. Insert one winding bar into the winding cone. Wind the spring by rotating the winding bar upwards. The number of turns required depends on the height of your garage door (typically around 30-36 quarter turns for a standard 7-foot door). Use the tape mark to guide you. Insert the second winding bar above the first to hold the tension as you move the first bar. Repeat this process until the spring is fully wound. Tighten the set screws on the winding cone securely.

Step 6: Secure the Cables

Ensure the lift cables are properly seated in the cable drums on either side of the garage door. Make sure the cables are taut and not tangled.

Step 7: Test the Garage Door

Remove the vice grips from the garage door tracks. Carefully lift the garage door manually to test its balance. It should move smoothly and stay in place when you release it. If the door is unbalanced, you may need to adjust the spring tension slightly by adding or removing a quarter turn.

Troubleshooting Common Issues

Door is still heavy: This indicates insufficient spring tension. Add a quarter turn to each spring, but be cautious not to overwind.

Door slams shut: This indicates excessive spring tension. Remove a quarter turn from each spring.

Cables are loose: Ensure the cables are properly seated in the cable drums and that the spring tension is sufficient to keep them taut.

Final Solution

Replacing garage door springs is a complex and potentially dangerous task.

FAQs

How long do garage door springs last?

Garage door springs typically last between 7 and 12 years, depending on usage and maintenance.

Should I replace both springs at the same time?

Yes, it’s highly recommended to replace both springs at the same time, even if only one is broken. This ensures balanced operation and prevents the other spring from failing shortly after.

How do I know what size springs to buy?

Measure the length, wire gauge, and inside diameter of your old springs. You can also consult with a garage door professional to ensure you get the correct replacement springs.
