Welcome to the MM Garage Door Repair Utah blog!

This is a repair that requires significant caution and expertise, and while we’re providing this information for educational purposes, we strongly recommend contacting our professional technicians for assistance. Garage door springs are under immense tension, and improper handling can lead to serious injury or even death.

Understanding Garage Door Springs and Cables

Garage door springs and cables work together to lift and lower your garage door. The springs provide the lifting force, while the cables connect the springs to the door, transferring that force. 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 sides of the door, above the horizontal tracks.

Cables run from the bottom brackets of the garage door, up and over a cable drum (for torsion springs) or through pulleys (for extension springs), and attach to the spring system. Over time, these components can wear out, rust, or break, requiring replacement.

Safety First

Before we proceed, let’s reiterate the importance of safety. Working with garage door springs is extremely dangerous. The springs are under high tension, and if released improperly, they can cause severe injury or even death. If you’re not experienced in this type of repair, please do not attempt it yourself. Contact MM Garage Door Repair Utah for professional assistance. If you choose to proceed, follow these safety precautions:

• Wear safety glasses and gloves.
• Use the correct tools.
• Never release the tension on a spring without proper instruction and equipment.
• If you are unsure about any step, stop and call a professional.

Tools and Materials Needed

If you’re determined to tackle this project yourself, you’ll need the following tools and materials:

• New garage door springs (matching the size and type of your existing springs)
• New garage door cables (matching the length and diameter of your existing cables)
• Winding bars (for torsion springs) or C-clamps (for extension springs)
• Vice grips
• Adjustable wrench
• Pliers
• Safety glasses
• Gloves
• Ladder

Replacing Torsion Springs

Replacing torsion springs is a complex process. Here’s a general overview, but remember that specific steps may vary depending on your garage door system.

1. Secure the Garage Door: Use vice grips to clamp the garage door track just above the rollers to prevent the door from moving.
2. Loosen the Set Screws: Locate the set screws on the spring’s winding cone. Use a wrench to loosen these screws.
3. Insert Winding Bars: Insert one winding bar into a winding cone hole, keeping a firm grip.
4. Unwind the Spring: Carefully unwind the spring by moving the winding bar upwards, releasing the tension in quarter-turn increments. Insert the second winding bar to hold the spring in place as you move the first. Repeat until the spring is fully unwound.
5. Remove the Old Spring: Once the spring is fully unwound, loosen the set screws on the stationary cone and slide the spring off the torsion tube.
6. Install the New Spring: Slide the new spring onto the torsion tube, ensuring it’s oriented correctly (the winding direction should match the original spring).
7. Wind the New Spring: Insert the winding bars and wind the spring the correct number of turns (refer to the spring’s specifications).
8. Tighten the Set Screws: Tighten the set screws on both the winding cone and the stationary cone.
9. Remove the Vice Grips: Carefully remove the vice grips from the garage door track.

Replacing Extension Springs

Replacing extension springs also requires caution. Here’s a general guide:

1. Secure the Garage Door: Use C-clamps to clamp the garage door track just above the rollers to prevent the door from moving.
2. Secure the Spring: Use a C-clamp to secure the spring to the track. This will prevent the spring from flying off when you disconnect it.
3. Disconnect the Old Spring: Disconnect the spring from the track and the cable.
4. Install the New Spring: Connect the new spring to the track and the cable.
5. Remove the C-Clamps: Carefully remove the C-clamps from the garage door track and the spring.

Replacing Garage Door Cables

Cable replacement is often done in conjunction with spring replacement. Here’s how to replace garage door cables:

1. Secure the Garage Door: Ensure the garage door is secured with vice grips or C-clamps, as described above.
2. Remove the Old Cable: Disconnect the old cable from the bottom bracket and the cable drum (for torsion springs) or the pulley (for extension springs).
3. Install the New Cable: Attach the new cable to the bottom bracket and thread it up and over the cable drum or through the pulley.
4. Tension the Cable: For torsion springs, wind the cable drum to tension the cable. For extension springs, adjust the spring tension to properly tension the cable.
5. Secure the Cable: Secure the cable to the cable drum or pulley.
6. Test the Door: Carefully test the garage door to ensure it operates smoothly and the cables are properly tensioned.

Adjusting Spring Tension

After replacing the springs and cables, it’s crucial to adjust the spring tension to ensure the garage door is properly balanced. The door should stay open at any point and close smoothly without slamming. If the door is too heavy or too light, you’ll need to adjust the spring tension accordingly. This process varies depending on the type of spring, so consult your garage door’s manual or contact a professional for guidance.

Troubleshooting Common Issues

Even after replacing the springs and cables, you might encounter some issues. Here are a few common problems and potential solutions:

• Door is uneven: This could indicate that the cables are not properly tensioned or that one spring is weaker than the other.
• Door is too heavy or too light: Adjust the spring tension to balance the door.
• Door is noisy: Lubricate the rollers, hinges, and tracks.

FAQs

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

A: Measure the length, wire gauge, and inside diameter of your old springs. You can also consult your garage door’s manual or contact a professional for assistance.

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

A: Garage door springs typically last for 5-10 years, depending on usage. If you notice any signs of wear or damage, such as rust, cracks, or sagging, it’s time to replace them.

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 both springs have the same tension and lifespan, preventing future problems.
