Broken Garage Door Spring: A DIY Guide to Replacement

Hey everyone, Today, we’ll be diving deeper into a common issue that many homeowners encounter – a broken garage door spring.

Your garage door’s smooth operation depends on the functionality of its springs, which act as counterweights to help the door open and close efficiently.

Unfortunately, these springs can break over time due to wear and tear, causing inconvenience and potential safety risks.

In this comprehensive guide, we’ll walk you through the process of replacing a broken garage door spring safely and effectively.

Understanding the Garage Door Spring

Before we get into the nitty-gritty of the replacement process, let’s gain a better understanding of the garage door spring’s function and the different types available.

Typically, garage doors operate with either torsion springs or extension springs. Torsion springs are located above the garage door and wind up when the door closes.

When you open the door, these springs unwind, assisting in lifting the heavy door. On the other hand, extension springs are positioned above the horizontal tracks on both sides of the garage door.

Identifying the Right Replacement Spring

Identifying the Right Replacement Spring

The key to a successful garage door spring replacement lies in selecting the right replacement. When purchasing a new spring, consider the following factors:

  • Rod Thickness: Measure the thickness of the rod on your existing spring. Ensure that the replacement spring matches this measurement for a proper fit.
  • Spiral Size: Pay attention to the size of the spiral or the space between the coils. This dimension directly affects the spring’s strength and its ability to lift the garage door.
  • Total Length: Measure the overall length of the spring to ensure that the replacement matches the existing one.

If you can’t find an exact match for your broken spring, it’s recommended to opt for a slightly stronger version with a thicker spring, ensuring adequate power and support.

Safety First: Proceed with Caution

Before we begin the replacement process, we must emphasize the importance of safety. Garage door springs are under immense tension and can pose significant risks if mishandled.

If you’re unsure about your ability to replace the spring safely, it’s best to hire a professional technician to handle the job. If you are sure let’s do it.

Assessing the Type and Size of the Broken Spring

Here are the steps on how to assess the type and size of a broken spring:

  1. Identify the location of the broken spring. This may be difficult if the spring is hidden inside a component. In this case, you may need to disassemble the component to access the spring.
  2. Once you have located the broken spring, inspect it carefully. Look for any identifying markings, such as the spring’s type, size, and material. If the spring is unmarked, you may need to measure it to determine its type and size.
  3. If the spring is unmarked and you cannot measure it, you may need to contact the manufacturer of the component to obtain the spring’s specifications.

Here are some additional tips for assessing the type and size of a broken spring:

  • If the spring is a compression spring, it will have coils that are wound in a tight spiral. If the spring is an extension spring, it will have coils that are wound in a loose spiral.
  • The type of spring can also be determined by its material. Compression springs are typically made of steel, while extension springs are typically made of stainless steel or phosphor bronze.
  • The size of the spring can be determined by measuring its diameter and length. The diameter is the width of the spring, and the length is the distance between the ends of the spring.

Once you have determined the type and size of the broken spring, you can order a replacement spring from a reputable supplier.
