For homeowners, the garage door serves as a primary point of access. It operates regularly throughout the year. When a garage door does not lift or makes a notable sound during operation, it often indicates a compromised spring.
Garage door springs manage the physical weight of the door panels. While the automatic opener directs the opening and closing movement, the springs support the load. When a spring fails, the door panels cannot be lifted easily, requiring service.
As a provider of garage door repair in Seattle, WA, CHS Garage Repair has prepared this guide to help you identify how these systems operate and the steps involved in normal repair work.
1. Torsion Springs vs. Extension Springs: What's the Difference?
Understanding which type of spring system is installed on your garage door is helpful before scheduling service. Residential installations generally feature one of two systems:
Torsion Springs: These are positioned horizontally on a steel shaft above the door opening. When the door is closed, cables attached to the bottom corners wind the springs to store mechanical energy. During opening, the springs unwind to assist in lifting the door panels. Torsion systems are common on modern installations and are built for durability. Learn more about their operation on our garage door torsion spring page.
Extension Springs (Tension Springs): These are installed horizontally along the tracks on both sides of the door. They stretch when the door closes and contract to provide lift when it opens. Because they expand and contract, safety cables are threaded through the center of the coils to keep them secure if they fail. For details on these systems, read our guide on garage door tension springs and our extension spring repair in Seattle service page.
2. Signs of a Broken Garage Door Spring
A garage door spring holds significant tension. When a spring fails, the symptoms are usually clear:
Loud Sound from the Garage: A steel spring releasing tension often produces a distinct, loud sound that can be heard from nearby rooms.
Minimal Door Movement: Modern openers use force-detection settings. If the opener attempts to lift a door with a broken spring, it detects the unassisted weight and stops after moving a few inches.
Visible Gap in the Spring: For torsion systems above the door, a clean break creates a clear gap of one to two inches in the coil.
Crooked Door Alignment: If one extension spring fails, the door only receives lift on one side, which can cause the door to twist or bind in the tracks. Learn about the repair process on our cable replacement page.
Loose Cables: When tension is lost, the steel lift cables can slip from the drums or hang loose. In these cases, you may require both spring adjustment and garage door cable replacement to restore proper function.
💡 Service Tip: If you suspect a broken spring, it is best to avoid using the automatic opener. Operating the system under these conditions can cause damage to the motor gear assembly.
3. Why Professional Repair is Recommended
While DIY projects are common for home maintenance, garage door spring service involves safety factors that require professional training.
Spring Tension: Torsion springs store mechanical force that can cause injury if handled without the proper tools, such as steel winding bars.
Precise Measurements: Service technicians use precise measurements of wire size, inner diameter, and overall length to select the correct replacement spring. Installing mismatched springs can affect the door balance and shorten the lifespan of the opener.
Door Balance: An unbalanced door can cause uneven wear on the rollers and tracks. Licensed technicians ensure the door is balanced during installation.

4. Recommended Steps When a Spring Fails
If you observe a broken spring, these steps are recommended:
Avoid pulling the red emergency release cord if the door is partially open, as the panels can drop without spring support.
Do not attempt to lift the door panels manually, as the full weight of the door can cause physical strain.
Keep the garage door opening clear of people and pets until a technician inspects the door.
Contact a qualified technician to measure and install the replacement springs.
