How to replace a broken spring 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 valuable information and solutions to keep your garage door operating smoothly and safely. Today, we’re tackling a common but potentially dangerous issue: replacing a broken garage door spring. While it might seem like a DIY project, it’s crucial to understand the risks involved and when to call in a professional. Let’s dive in!

Understanding Garage Door Springs

Garage door springs are the unsung heroes responsible for lifting and lowering your heavy garage door. They work under immense tension, and when one breaks, it can create a hazardous situation. There are typically two types of springs: torsion springs, mounted above the door, and extension springs, located along the sides of the door. This guide will primarily focus on torsion springs, as they are more common in modern garage door systems.

Why Replacing a Garage Door Spring is Dangerous

Before we proceed, it’s essential to emphasize the dangers involved. Garage door springs store a tremendous amount of energy. When a spring breaks, that energy is released suddenly and violently. Attempting to replace a spring without the proper tools, knowledge, and experience can lead to serious injury, including broken bones, lacerations, and even death. If you’re not completely comfortable with this process, please, for your own safety, contact MM Garage Door Repair Utah at 801-418-9217. We’re here to help!

Tools and Materials Needed

If you’re confident in your abilities and understand the risks, here’s a list of the tools and materials you’ll need:

• New garage door spring (correct size and type)
• Winding bars (correct size for your spring)
• Safety glasses
• Work gloves
• Adjustable wrench
• Socket set
• Vice grips
• Ladder

Important Tip: Always replace both springs, even if only one is broken. This ensures balanced operation and prevents the other spring from breaking soon after.

Step-by-Step Guide to Replacing a Torsion Spring

Safety First: Disconnect the garage door opener from the power outlet. This prevents accidental operation during the repair process.

Step 1: Secure the Door: Clamp the garage door to the tracks using vice grips or C-clamps. This prevents the door from crashing down while you’re working on the springs.

Step 2: Loosen the Set Screws: Locate the set screws on the spring’s winding cone (the cone at the end of the spring). Use an adjustable wrench to loosen these screws. Be extremely careful, as the spring is still under tension.

Step 3: Unwind the Broken Spring: Insert a winding bar into one of the holes in the winding cone. Hold the winding bar firmly and slowly release the tension on the spring by carefully unwinding it. Count the number of quarter turns as you unwind. This is crucial for winding the new spring later. Repeat this process until the spring is completely unwound.

Step 4: Remove the Old Spring: Once the spring is unwound, loosen the set screws on the stationary cone (the cone attached to the center bracket). Slide the spring off the torsion tube.

Step 5: Install the New Spring: Slide the new spring onto the torsion tube, ensuring it’s oriented correctly (check the spring’s winding direction). Secure the stationary cone by tightening the set screws.

Step 6: Wind the New Spring: Insert a winding bar into the winding cone. Carefully wind the spring the same number of quarter turns you counted when unwinding the old spring. This will put the spring under the correct amount of tension.

Step 7: Tighten the Set Screws: Once the spring is fully wound, tighten the set screws on the winding cone securely.

Step 8: Secure the Torsion Tube: Ensure the torsion tube is properly secured to the header bracket. This is important for the safe and efficient operation of the garage door.

Step 9: Remove the Clamps: Carefully remove the vice grips or C-clamps from the garage door tracks.

Step 10: Test the Door: Manually lift and lower the garage door to ensure it operates smoothly and is properly balanced. If the door is difficult to lift or falls quickly, you may need to adjust the spring tension.

Step 11: Reconnect the Opener: Reconnect the garage door opener to the power outlet.

Troubleshooting Tips

Door is Still Unbalanced: If the door is still unbalanced after replacing the springs, you may need to adjust the spring tension slightly. Add or remove a quarter turn at a time until the door is properly balanced.

Springs are Noisy: Apply a garage door lubricant to the springs to reduce noise and friction.

Door is Difficult to Open: Check for obstructions in the tracks or damaged rollers. These can make the door difficult to open, even with new springs.

FAQs

Q: How do I know what size spring to buy?

A: Measure the length, wire size (diameter), and inside diameter of the old spring. You can also find this information on a sticker located on the spring itself or the garage door.

Q: Can I replace just one spring?

A: While technically possible, it’s highly recommended to replace both springs at the same time. This ensures balanced operation and prevents the other spring from breaking soon after.

Q: How often should I replace my garage door springs?

A: Garage door springs typically last for 7-10 years, depending on usage. Inspect your springs regularly for signs of wear and tear, such as rust, cracks, or stretching.
