Knowing how to replace garage door springs is essential for maintaining the safety and functionality of your garage. Over time, these springs can wear out or break, making operating the door difficult and even dangerous. This guide provides a detailed, step-by-step process to safely replace both torsion and extension springs, along with tips to identify when your spring needs replacement and the necessary tools.
Garage door springs are under a lot of tension, and improper handling can lead to severe injuries. Torsion springs, mounted above the garage door, and extension springs, located along the sides, require careful attention during replacement. Signs such as difficulty lifting the door, visible gaps in the spring, or a loud bang often indicate a broken spring needing immediate replacement.
While DIY replacement is possible with the right tools and precautions, knowing when to call a professional is crucial, especially if you’re unfamiliar with the process. Keep reading to learn how to safely replace your garage door spring and ensure smooth operation for years.
Understanding Garage Door Springs
Before diving into the replacement process, it’s essential to understand the two main types of garage door springs: torsion springs and extension springs. Each has its mechanism and requires a different replacement approach.
Torsion Springs
Torsion springs are mounted horizontally above the garage door. They work by twisting as the door closes, storing energy, and releasing it when it opens. These springs are known for their durability and ability to support heavy doors. However, they are also under significant tension, making them more dangerous to handle.
Extension Springs
Extension springs are mounted on either side of the garage door and run parallel to the horizontal tracks. They stretch as the door closes and contract as it opens. While they are less durable than torsion springs, they are more commonly found in lighter, single-car garage doors.
Signs That Your Garage Door Spring Needs Replacing
Knowing when to replace your garage door spring is crucial to avoid accidents or damage to your garage door opener. Here are some common signs that indicate it’s time for a replacement:
Difficulty Opening or Closing the Door
If your garage door suddenly becomes heavy or difficult to lift, this could be a sign that the spring has lost tension or broken entirely. The door may also stop midway or close unevenly, indicating that the spring can no longer support the door’s weight.
Visible Gaps in the Spring
A visible gap in the spring coil is a clear sign of a broken spring. This gap means the spring has snapped and can no longer function correctly. If you notice this issue, you should avoid using the door, as it can become unstable.
Loud Noises During Operation
If you hear a loud bang coming from your garage, a spring has likely snapped. The noise occurs when the tension in the spring is suddenly released. In such cases, avoiding using the door until the spring has been replaced is best.
Crooked or Misaligned Door
A misaligned garage door that appears crooked or uneven when opening or closing can indicate a broken or worn-out spring. If not addressed promptly, this misalignment can lead to further damage to the door or the opener.
Tools and Safety Equipment Needed for Replacing a Garage Door Spring
Replacing a garage door spring requires specific tools and safety equipment to ensure the job is done correctly and safely. Here’s what you’ll need:
Tools
- Winding bars: Essential for safely winding and unwinding torsion springs.
- Adjustable wrench: For tightening and loosening nuts and bolts.
- Socket wrench set: To remove and install bolts.
- Clamps: To secure the garage door in place during the replacement.
- Tape measure: For measuring the spring and ensuring proper replacement.
- Marker or chalk: For marking the position of the spring and other components.
Safety Equipment
- Safety glasses: To protect your eyes from debris or accidental spring release.
- Gloves: To protect your hands from sharp edges and provide a better grip.
- Long-sleeved shirt and pants: To protect your skin from potential scrapes or bruises.
- Hard hat: Recommended if working in a tight or low-ceiling garage to prevent head injuries.
How to Replace a Torsion Spring
Due to the high tension involved, replacing a torsion spring requires precision and attention to detail. Follow these steps carefully to replace the spring safely.
Step 1: Secure the Door
Start by disconnecting the garage door opener and clamping the door in place to prevent it from moving. Place the clamps on the tracks below the bottom rollers to keep the door from lifting.
Step 2: Release Tension from the Old Spring
Insert a winding bar into one of the holes in the winding cone of the spring. Hold the bar securely while loosening the set screws on the winding cone with an adjustable wrench. Slowly and carefully release the tension in the spring by moving the bar in a downward direction.
Step 3: Remove the Old Spring
Once the tension is released, remove the spring from the center bracket. Use a socket wrench to remove the bolts connecting the spring to the center bracket. If your door has two torsion springs, repeat the process for the other side.
Step 4: Measure the Old Spring
Measure the old spring’s length, wire size, and inside diameter to ensure you purchase the correct replacement. These measurements are crucial for the proper operation of the new spring.
Step 5: Install the New Spring
Slide the new spring onto the torsion tube and secure it to the center bracket with bolts. Ensure the spring is centered and positioned correctly before tightening the set screws.
Step 6: Wind the New Spring
Using winding bars, carefully wind the new spring in the opposite direction of the old spring. Most springs require 30 to 36 quarter-turns but refer to the manufacturer’s instructions for the exact number. Make sure the spring is wound evenly to prevent imbalance.
Step 7: Test the Door
Remove the clamps and reattach the garage door opener. Test the door to ensure it opens and closes smoothly. If the door is difficult to open or close, you may need to adjust the tension in the spring.
How to Replace an Extension Spring
Replacing an extension spring is generally less dangerous than a torsion spring but still requires caution. Here’s how to replace it safely:
Step 1: Secure the Door
Disconnect the garage door opener and use clamps to secure the door in the open position. This will prevent the door from moving during the replacement process.
Step 2: Release Tension from the Old Spring
Carefully detach the safety cable and use pliers to disconnect the spring from the track hanger. Slowly release the tension in the spring to avoid snapping.
Step 3: Remove the Old Spring
Remove the old spring from the mounting brackets. If your door has two extension springs, replace them both to ensure even tension.
Step 4: Measure the Old Spring
Measure the length of the old spring and note its weight capacity and color coding, which indicates its strength. Purchase a new spring with the exact specifications to ensure proper functionality.
Step 5: Install the New Spring
Attach the new spring to the mounting brackets and reconnect the safety cable. Ensure the spring is securely fastened to prevent slipping or snapping.
Step 6: Test the Door
Remove the clamps and reattach the garage door opener. Test the door to ensure it operates smoothly. If the door is not balanced, adjust the spring tension accordingly.
Safety Tips for Replacing Garage Door Springs
Replacing garage door springs can be hazardous if not done correctly. Here are some safety tips to keep in mind:
Work with a Partner
Having someone assist you can provide extra hands and eyes to ensure safety. They can help hold the door, pass tools, or call for help if needed.
Use the Right Tools
Always use the appropriate tools, such as winding bars for torsion springs. Improvising with incorrect tools can lead to accidents or damage to the door system.
Don’t Rush the Process
Take your time and follow each step carefully. Rushing can lead to mistakes, injuries, or improper installation, which can cause the door to malfunction.
Know When to Call a Professional
If you’re unsure about any step or feel uncomfortable handling the tension in the springs, it’s best to call a professional. Garage door springs are under immense pressure and can cause severe injuries if mishandled.
When to Call a Professional
While DIY replacement can save money, it’s best to call a professional in some situations. Here’s when you should consider hiring an expert:
Complex Systems
If your garage door has a complex spring system or is part of an automated system, professional help is recommended. They have the tools and expertise to handle intricate installations safely.
Lack of Experience
If you’re unfamiliar with garage door mechanisms, leaving the job to someone with experience is safer. A professional can complete the task more efficiently and ensure everything is done correctly.
Limited Access to Tools
Replacing garage door springs requires specialized tools. If you don’t have access to these tools or are unsure about using them, hiring a professional is best to avoid potential hazards.
