How to replace the spring on a garage door?

Welcome back to the MM Garage Door Repair Utah blog! As your trusted local garage door experts, we often get asked about DIY repairs. One of the most common questions is: “How do I replace the spring on my garage door?” While we always recommend professional service for safety reasons, we understand the desire to tackle home repairs yourself. This comprehensive guide will walk you through the process, but please remember that garage door springs are under extreme tension and can cause serious injury or even death if handled improperly.

Understanding Garage Door Springs

Before we dive into the replacement process, it’s crucial to understand the different types of garage door springs. The two main types are torsion springs and extension springs. Torsion springs are mounted above the garage door opening, while extension springs run along the horizontal tracks on either side of the door. This guide primarily focuses on replacing torsion springs, as they are more common in modern garage doors. However, the principles of safety and caution apply to both types.

Safety First

This cannot be stressed enough: working with garage door springs is dangerous. The springs are under immense tension, and releasing that tension incorrectly can lead to severe injury. Always wear safety glasses and gloves. Have a helper present. If you’re not comfortable with any of these steps, please call a professional.

Tools and Materials You’ll Need

To replace a garage door spring, you’ll need the following tools and materials:

• New garage door spring (correct size and type)
• Winding bars (correct size for your spring)
• Safety glasses
• Gloves
• Wrench
• Socket set
• Vice grips or locking pliers
• Ladder

Make sure you have the correct replacement spring. The spring’s size and type are crucial for proper operation and safety. Measure the old spring’s length, wire diameter, and inside diameter. If you’re unsure, consult with a garage door professional.

Step-by-Step Guide to Replacing a Torsion Spring

Now, let’s get into the actual replacement process. Remember to proceed with extreme caution and double-check each step.

Step 1: Secure the Garage Door

Before you do anything else, ensure the garage door is completely closed. Clamp the door to the tracks using vice grips or locking pliers to prevent it from accidentally opening during the spring replacement process. This is a critical safety measure.

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 a wrench to loosen these screws. Do not remove them completely at this stage.

Step 3: Insert Winding Bars and Unwind the Spring

This is the most dangerous part of the process. Insert one winding bar into a hole in the winding cone. Hold the bar firmly and loosen the set screws completely. Slowly and carefully unwind the spring by moving the winding bar upwards. Insert the second winding bar into the next hole to secure the spring as you unwind. Repeat this process until all the tension is released from the spring. Count the number of quarter turns it takes to unwind the spring. This number is important for winding the new spring.

Step 4: Remove the Old Spring

Once the spring is completely unwound, loosen the set screws on the stationary cone (the cone attached to the center bearing plate). Slide the spring off the torsion tube. If the spring is broken, you may need to remove the broken pieces separately.

Step 5: Install the New Spring

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

Step 6: Wind the New Spring

Insert one winding bar into a hole in the winding cone. Wind the spring by moving the winding bar downwards. Insert the second winding bar into the next hole to secure the spring as you wind. Repeat this process until you’ve wound the spring the same number of quarter turns you counted when unwinding the old spring. Add an additional quarter turn or two to compensate for the door’s weight.

Step 7: Tighten the Set Screws

Once the spring is fully wound, tighten the set screws on the winding cone securely. Remove the winding bars carefully.

Step 8: Lubricate the Spring

Apply a garage door lubricant to the spring to ensure smooth operation and prevent rust.

Step 9: Test the Garage Door

Remove the vice grips or locking pliers from the tracks. Carefully test the garage door by opening and closing it manually. It should move smoothly and easily. If the door is difficult to open or close, or if it doesn’t stay in place when partially open, you may need to adjust the spring tension.

Adjusting Spring Tension

If the garage door is not balanced correctly, you can adjust the spring tension by adding or removing quarter turns. Be careful when making adjustments, and always re-tighten the set screws after each adjustment.

Final Solution

Congratulations! You’ve (hopefully) successfully replaced your garage door spring. Remember to regularly inspect your garage door springs for signs of wear and tear. Proper maintenance can extend the life of your springs and prevent future problems.

FAQs

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

A: Garage door springs typically last for 7-10 years, or around 10,000 cycles (opening and closing). However, this can vary depending on the quality of the spring and the frequency of use.

Q: Can I replace just one spring?

A: It’s generally recommended to replace both springs at the same time, even if only one is broken. This ensures that the door is balanced correctly and prevents the other spring from failing prematurely.

Q: What if I don’t feel comfortable replacing the spring myself?

A: That’s perfectly fine! Garage door spring replacement is a dangerous task, and it’s always best to err on the side of caution. Call a professional garage door technician for assistance.

Safety Note

Again, we must emphasize the importance of safety when working with garage door springs. If you are not comfortable with any of the steps outlined above, please call a professional. Garage door springs are under extreme tension and can cause serious injury or even death if handled improperly.
