Understanding Garage Door Springs

Before diving into how to fix a garage door spring, it’s important to understand the different types of springs and how they work. There are two types of garage door springs: extension springs and torsion springs.

  • Extension Springs: These are found on either side of the garage door, stretching alongside the horizontal tracks. They expand and contract to balance the door’s weight.
  • Torsion Springs: These are positioned horizontally above the garage door opening. They store mechanical energy by twisting. When the door opens, the springs unwind, helping to lift the door.

Both types of springs are under high tension and can be dangerous if not handled properly.

Signs Your Garage Door Spring Needs Fixing

Identifying the problem early can prevent further damage to your garage door system. Here are some signs that your garage door spring might need fixing:

  • Difficulty Opening the Door: If the door is heavy and hard to lift, the spring might be broken or damaged.
  • Visible Gap in the Spring: A visible gap in a torsion spring indicates that it is broken.
  • Loud Bang: A loud noise like a gunshot can mean a spring has snapped.
  • Door Closes Too Fast: A door that closes rapidly might have a broken spring, making it unsafe.

Safety Precautions Before Fixing a Garage Door Spring

When dealing with garage door springs, safety is the most important consideration. Here are some safety precautions to follow:

  • Disconnect the Garage Door Opener: Ensure the door opener is unplugged to prevent accidental activation.
  • Use Proper Tools: Only use tools designed for garage door repairs.
  • Wear Safety Gear: Wear safety glasses and gloves to protect yourself from potential injuries.
  • Work with a Partner: Having someone to assist you can make the process safer and easier.

How to Fix a Garage Door Spring

Step 1: Gather the Necessary Tools

Before starting the repair, gather all the tools you’ll need:

  • Winding bars (for torsion springs)
  • Wrenches
  • Clamps
  • Ladder
  • Replacement springs (make sure they match the specifications of the old springs)

For torsion springs, insert a winding bar into the winding cone and slowly release the tension by turning the bar in the direction opposite to how the spring was wound. Do this carefully to avoid any sudden releases of tension.

Step 5: Remove the Old Spring

Once the tension is released, remove the old spring from the shaft. This usually involves loosening set screws and sliding the spring off the shaft.

Step 6: Install the New Spring

Slide the new spring onto the shaft and make sure it’s properly centered. Tighten the set screws to secure the spring in place.

Step 7: Wind the New Spring

Using the winding bars, wind the new spring in the correct direction. Follow the manufacturer’s recommendations for the number of turns required. This step requires precision to ensure the door operates smoothly.

Step 8: Test the Door

Once the spring is wound, remove the clamps or locking pliers and reconnect the garage door opener. Test the door many times to confirm it opens and closes properly.
