How to adjust garage door with two springs?

Welcome to the MM Garage Door Repair Utah blog! As your trusted local garage door experts, we often get asked about DIY garage door adjustments. Today, we’re tackling a common question: “How do I adjust a garage door with two springs?” While we always recommend professional service for safety and optimal performance, we understand the desire to troubleshoot minor issues yourself. This guide will provide some basic information, but please remember that garage door springs are under immense tension and can cause serious injury if handled improperly. If you’re uncomfortable with any of these steps, please don’t hesitate to call us at 801-418-9217 or visit mmgaragedoorrepair.com for expert assistance.

Understanding Garage Door Spring Systems

Before we dive into adjustments, it’s crucial to understand how your garage door spring system works. Most residential garage doors use a torsion spring system, which consists of one or two springs mounted horizontally above the door. These springs store energy when the door is closed and release it to help lift the door open. Having two springs generally means the door is heavier, requiring more lifting power. It also provides a degree of redundancy – if one spring breaks, the other might prevent the door from crashing down (though it’s still crucial to replace both immediately).

The springs are connected to a torsion tube, which is anchored to the header above the door. Cables run from drums on either end of the torsion tube down to the bottom brackets of the door. When the door is raised, the springs unwind, turning the torsion tube and winding the cables onto the drums, lifting the door.

Safety First

WARNING: Garage door springs are under extreme tension. Improper handling can result in serious injury or death. If you are not comfortable working with high-tension springs, please contact a qualified garage door technician. Never attempt to adjust or repair a broken spring yourself.

Before you begin any adjustments, ensure the following:

• Wear safety glasses: Protect your eyes from flying debris.
• Disconnect the garage door opener: Unplug the opener from the outlet to prevent accidental operation.
• Use proper tools: Use the correct winding bars for your spring size.
• Work with a partner: Having someone to assist you can make the process safer and easier.

Identifying the Problem

Before making any adjustments, accurately diagnose the issue. Common problems with garage doors that might require spring adjustment include:

• The door is uneven: One side of the door is higher than the other.
• The door is difficult to open or close: The door feels heavy or sluggish.
• The door slams shut: The springs are not providing enough counter-balance.
• The door doesn’t stay open: The springs are not holding the door in the open position.

Adjusting Torsion Springs (Step-by-Step)

Note: This guide assumes you have torsion springs. If you have extension springs (located on the sides of the door), the adjustment process is different and even more dangerous. We strongly recommend calling a professional for extension spring adjustments.

Here’s how to adjust torsion springs, assuming you’ve identified the problem and taken all necessary safety precautions:

1. Secure the door: Clamp the door to the track with locking pliers or C-clamps to prevent it from moving during the adjustment process.
2. Loosen the set screws: Locate the set screws on the winding cone of the spring you want to adjust. Use a wrench to loosen them, but don’t remove them completely.
3. Insert winding bars: Insert one winding bar into a winding hole on the winding cone. Hold the bar firmly.
4. Add or release tension:
   • To add tension (if the door is too heavy or slams shut): Insert the second winding bar into another winding hole. Push the first winding bar upwards to wind the spring tighter. Secure the second winding bar and remove the first. Repeat this process in small increments (usually ¼ turn at a time).
   • To release tension (if the door is too light or difficult to close): Hold the winding bar firmly and slowly release tension by moving the bar downwards. Be extremely careful, as the spring can unwind rapidly. Secure the second winding bar and remove the first. Repeat this process in small increments.
5. Tighten the set screws: Once you’ve made the desired adjustment, tighten the set screws securely.
6. Repeat on the other spring (if necessary): If you have two springs and the door is uneven, you may need to adjust the other spring as well. Make small adjustments and check the door’s balance after each adjustment.
7. Test the door: Remove the clamps and carefully test the door’s operation. It should open and close smoothly and stay in the open position without assistance.

Fine-Tuning and Troubleshooting

After making the initial adjustments, you may need to fine-tune the springs to achieve perfect balance. If the door still feels slightly off, repeat the adjustment process in very small increments (1/8 turn or less). Be patient and methodical. If you’re still having trouble, it’s best to call a professional.

Here are some additional troubleshooting tips:

• Squeaking or grinding noises: Lubricate the springs, rollers, and hinges with a garage door lubricant.
• Door is still uneven: Check the tracks for obstructions or damage. Make sure the rollers are properly seated in the tracks.
• Springs are old or worn: If your springs are more than 5-7 years old, they may be losing their tension and need to be replaced.

Final Solution

The final solution to adjusting garage door with two springs involves a combination of careful observation, precise adjustments, and a healthy dose of caution. Remember to always prioritize safety and seek professional help when needed. By following the steps outlined above, you can often resolve minor balance issues and keep your garage door operating smoothly.

FAQs

Q: How many turns should I wind my garage door spring?

A: The number of turns depends on the height of your garage door. A general rule of thumb is one full turn per foot of door height, plus an additional quarter turn. However, it’s best to consult a professional or refer to the spring manufacturer’s specifications for accurate guidance.

Q: Can I replace just one garage door spring?

A: No. If one spring breaks, you should always replace both springs at the same time. This ensures that the door is properly balanced and prevents premature failure of the remaining spring.

Q: How do I know if my garage door springs are broken?

A: Signs of a broken spring include a loud bang, a visible gap in the spring, a door that is difficult to lift, or a door that slams shut.
