Types of Garage Door Springs

Before delving into the repair process, it's essential to understand the two primary types of garage door springs: torsion springs and extension springs.

  • Torsion Springs:
    • Located above the garage door opening.
    • Wind up and unwind to generate torque for lifting and lowering the door.
    • Typically used in heavier garage doors.
  • Extension Springs:
    • Mounted on the sides of the garage door.
    • Extend and contract to provide lifting force.
    • Commonly found in lighter garage doors.

Understanding the type of spring system your garage door employs will help you identify potential issues and select the appropriate repair approach.

Signs of a Broken Garage Door Spring

Recognizing the signs of a broken garage door spring is vital for timely repair. Look out for the following indicators:

  • Visible Damage:
    • Observe the springs for visible signs of wear, rust, or breakage.
    • Broken springs may appear elongated, twisted, or separated into two pieces.
  • Unusual Noises:
    • Pay attention to any loud bangs or snaps during door operation.
    • A sudden, loud noise often indicates a spring breakage.
  • Imbalanced Door:
    • An unbalanced garage door is a clear sign of a broken spring.
    • If the door appears slanted or uneven when in the closed or open position, it likely has a broken spring.
  • Difficulty Opening or Closing:

    • You may notice increased resistance or the door refusing to stay open.
  • Gap in the Spring:
    • In some cases, a broken spring might result in a visible gap in the spring coil.

Broken Garage Door Spring Repair Process

Repairing a broken garage door spring involves several steps. While it's always recommended to hire a professional, understanding the process can help you grasp the complexity of the task. Here's a general overview:

  • Safety Measures:
    • Before starting any repair work, ensure you disconnect the power supply to the garage door opener.
    • Use clamps or vice grips to secure the door in the open position to prevent accidental closure.
  • Assessment and Preparation:
    • Inspect the broken spring and surrounding components for any damage.
    • Measure the dimensions of the broken spring to ensure the replacement matches the specifications.
  • Spring Replacement:
    • Torsion Spring Replacement:
      • Use winding bars to release tension from the existing spring.

    • Extension Spring Replacement:
      • Unhook the extension springs from their brackets.
      • Replace the broken spring with a new one of the same dimensions.
      • Reattach the springs, ensuring proper tension and alignment.
  • Safety Cable Installation:
    • For torsion spring systems, it is crucial to install safety cables.

  • Balance and Adjustment:
    • Test the door's balance by manually operating it to ensure it moves smoothly.
    • Make any necessary adjustments to the spring tension or track alignment to ensure optimal door performance.

Essential Safety Precautions

  • Wear Protective Gear:
    • When inspecting or handling broken springs, wear safety glasses, gloves, and sturdy footwear.
    • Protective gear helps minimize the risk of injury from flying debris or accidental contact.
