How To Repair A Broken Garage Door Spring

Repairing a broken garage door spring is a task that can be quite challenging and potentially dangerous. It requires attention to detail, a strict adherence to safety precautions, and the right tools. Below, I will guide you through the step-by-step process of fixing a broken garage door spring.

Safety First

Before attempting any repair, safety must be your top priority.

  • Wear protective gear: Safety goggles and gloves are essential.
  • Secure the door: Use C-clamps or locking pliers to secure the door from opening.
  • Unplug the opener: If you have an automatic opener, disconnect it to prevent accidental activation.

Identifying the Spring Type

Garage doors typically use one of two types of springs:

  1. Torsion springs, which are mounted above the closed garage door.
  2. Extension springs, located above the upper tracks on both sides.

Knowing which type you have is crucial because the repair processes differ.

Tools and Materials Needed

  • Winding bars
  • Adjustable wrench
  • Socket set
  • C-clamps or locking pliers
  • Safety goggles
  • Gloves

Detailed Repair Process

For Torsion Springs:

  1. Secure the Door: Keep the garage door closed and secure it with C-clamps on the track.
  2. Unwind the Spring: Insert a winding bar into the winding cone and slowly unwind the spring.
  3. Detach the Spring: Use an adjustable wrench to loosen the set screws and detach the spring from the center bracket.
  4. Remove the Spring: Slide the spring off the bar after removing any necessary hardware.
  5. Replace the Spring: Slide the new spring in place, secure it, and wind it according to the manufacturer’s instructions.

For Extension Springs:

  1. Secure the Door: Keep the garage door open and secure it with C-clamps under the bottom rollers.
  2. Disconnect the Spring: Disconnect the spring from the track bracket and the pulley.
  3. Replace the Spring: Attach the new spring to the pulley and track bracket.
  4. Adjust the Tension: Adjust the tension as needed by pulling on the lift cable.

Frequently Asked Questions

How do I know if my garage door spring is broken?

The door may not open, or you might see a visible gap in the torsion spring. An extension spring may hang down.

Can I replace my garage door spring myself?

It’s possible, but not recommended unless you have the right tools and experience. The tension in the springs can be dangerous.

How long do garage door springs last?

Typically, springs have a lifespan of 10,000 cycles. With average use, this usually amounts to 7-9 years.
