Types of Garage Door Springs
Before starting any replacement process, it is essential to understand the type of spring your garage door uses. Garage doors typically use extension or torsion springs; each type functions differently. Knowing the differences will help you approach the repair safely and effectively.
Extension Springs
Extension springs are parallel to the horizontal tracks on both sides of the garage door. These springs extend as the door closes and contract when it opens, essentially pulling the door upward. They are often found in lighter, smaller garage doors like those used for single-car garages. One advantage is that they are easier to install and replace, making them ideal for DIY replacements. However, they are less durable than torsion springs and require frequent adjustments.
Torsion Springs
Torsion springs, in contrast, are installed horizontally above the garage door on a metal shaft. These springs store energy through a twisting motion, applying torque to lift the door smoothly. Torsion springs are more robust and last longer, making them ideal for heavier or frequently used garage doors. Due to their complexity and significant tension, replacing torsion springs is more complicated and dangerous than extension springs.
Signs Your Garage Door Springs Need Replacement
It’s essential to recognize the early signs that your garage door springs need replacement to avoid sudden failure, which could lead to accidents or more costly repairs.
Visual Indicators
Routine inspections can help you catch problems early. Signs that your springs may need to be replaced include:
- Rust: Corrosion weakens the spring over time, causing it to snap suddenly.
- Gaps in the coil: The spring is likely overstretched and ineffective if you see gaps between the coils.
- Broken springs: If a spring has broken into two or more pieces, it needs immediate replacement. A loud bang usually accompanies a break.
Garage Performance Issues
Garage door springs do most of the heavy lifting. If you notice performance issues such as:
- The door feels heavy or challenging to lift manually.
- The door won’t stay in the fully open position.
- The opener strains to lift the door or operates slower than usual. These are all signs that your springs may be worn out or broken and need replacing. Other indicators include unusual noise during operation, such as grinding or squealing sounds, which could mean the springs are under strain.
Safety Considerations for DIY Garage Spring Replacement
Garage door springs, especially torsion springs, are under extreme tension, making them dangerous to handle. Always take appropriate safety measures when attempting DIY replacement.
Protective Gear
Before starting any repair, ensure you have the right protective gear. This includes:
- Thick gloves: To protect your hands from sharp edges and sudden snaps.
- Safety goggles: To shield your eyes from any debris or flying parts.
- Closed-toe shoes: Steel-toe boots protect your feet if tools or parts fall.
- Helper: Someone assisting you can make the process smoother and safer by stabilizing the door or passing tools.
In addition, make sure to work on the door when it’s fully closed and unplug the automatic opener to prevent it from being accidentally engaged.
How to Replace Extension Springs on a Garage Door
Replacing extension springs is less complex than torsion springs, making it a manageable DIY project with the right tools and steps.
Tools and Equipment Needed
Before starting, gather the necessary tools:
- Adjustable wrench
- Safety glasses and gloves
- Locking pliers or clamps
- Tape measure
- Replacement springs (properly sized)
- Step ladder
- Socket wrench set
Measure and Purchase New Springs
To buy the correct replacement springs, you need to measure the old ones:
- Length: Measure the entire length of the spring when it’s uncompressed.
- Wire thickness: Measure the thickness of the spring wire using a caliper or a ruler.
- Color coding: Most extension springs have color-coded ends indicating their strength. Match this color when purchasing your replacements.
Installing New Extension Springs
- Disconnect the power: Unplug the garage door opener to prevent accidental operation.
- Release the tension: Fully open the garage door and secure it using clamps or locking pliers. This ensures the door won’t move while you work on the springs.
- Remove the old springs: Detach the spring from the mounting brackets and the track. Pay attention to how the spring is attached to ensure correct reinstallation.
- Install the new springs: Attach the new spring to the same brackets and track where the old one was removed. Ensure the hooks and loops are securely fastened, and the tension is even on both sides.
- Test the door: Carefully remove the clamps and lower the door to check its operation. Reconnect and test the opener several times to ensure the door operates smoothly.
How to Replace Torsion Springs on a Garage Door
Due to the high tension involved, replacing torsion springs is more technical and dangerous. It requires precision, strength, and specialized tools.
Tools and Equipment Needed
To replace torsion springs, you’ll need:
- Winding bars (never use screwdrivers or improvised tools)
- Adjustable wrench
- Vice grips or C-clamps
- Socket wrench set
- Tape measure
- Replacement torsion springs (properly measured)
Measure and Buy New Springs
To find the right replacement spring, measure:
- Wire diameter: Use a caliper to measure the thickness of the wire.
- Spring length: Measure the overall length of the spring when it’s uncompressed.
- Inside diameter: This is the diameter of the spring’s inner hole.
- Wind direction: Check if your spring is left or right-wind by its placement.
Installing New Torsion Springs
- Release the tension: Use the winding bars to slowly and safely unwind the tension in the old springs. This is a critical safety step, as improper handling can cause the spring to snap.
- Remove the old springs: After the tension is released, loosen the set screws on the torsion tube and slide off the old spring.
- Install the new torsion springs: Slide the new spring onto the tube, ensuring it is correctly oriented (right-wind or left-wind). Tighten the set screws.
- Wind the new springs: Using the winding bars, apply the correct number of turns based on the manufacturer’s instructions. This typically involves applying about 30-35 quarter turns.
- Test the door: Once the springs are wound, manually lift the door to check for balance. When left halfway open, it should remain in place.
Troubleshooting Common Issues After Garage Spring Replacement
Even after successful installation, you may encounter minor issues. Here’s how to address them.
Garage Door Balance Problems
If the garage door doesn’t stay open or closes too quickly after the spring replacement, the springs may not be balanced correctly. Test the door manually by lifting it halfway. If it falls or rises, you need to adjust the spring tension.
Spring Tension Adjustments
For extension springs, adjust the tension by repositioning the hook on the end of the spring. For torsion springs, carefully add or remove a quarter turn using the winding bars until the door moves smoothly and is balanced.
When To Call a Professional for Your Garage
While DIY replacements can save you money, there are instances where a professional’s expertise is necessary.
Complex Installation Scenarios
If your garage door has a custom spring setup or multiple doors, or the spring size and configuration seem complicated, calling a professional ensures the job is done safely and correctly.
