Learn how garage door springs work, how to identify a broken spring, and why proper sizing and safe replacement are critical for your safety and your door’s performance.

Garage door springs are the heart of the system. They bear the massive weight of the door, making them extremely dangerous when broken or when repair is attempted without proper expertise. This comprehensive guide from Guide To Garage Door Repair aims to equip you with the precise knowledge to safely diagnose the issue and determine if you need professional help

In this guide, we will cover how to easily distinguish between Torsion Springs (mounted above the door) and Extension Springs (mounted on the sides of the tracks). Understanding this difference is the crucial first step in finding the correct replacement.

Read on for our detailed guide on accurate spring measurement, deciphering color code charts, and the safest replacement steps for both types. Our goal is to ensure your garage door operates efficiently and with complete safety
How to Tell If Your Spring is Broken? (Initial Diagnosis)

Clear Signs of Breakage: Explain that a broken spring results in a door that is extremely heavy to lift manually, often preceded by a “loud bang or gunshot-like noise” when it snaps.
