QUICK ANSWER
If you heard a loud bang and now the door will not lift, a spring has most likely broken. Stop using the door and call a technician. Springs hold a lot of tension, so they are not a safe DIY repair.
Springs do the heavy lifting, not the opener. A standard torsion spring is rated for about 10,000 open-and-close cycles, which is roughly 7 to 10 years for most homes. When one breaks, the opener may hum or strain but the door stays down.

Why the right spring matters
A new spring has to match your door’s weight and size. The wrong spring makes the door heavy, fast, or unbalanced, and it wears out the opener too. When one spring breaks on a two-spring door, the other one is usually close behind, so we will tell you if replacing both makes sense. Near the beach, salt air can rust springs early. See how SoCal weather affects springs.

What can cause the problem?
Repeated lifting cycles
Springs carry the door through repeated opening and closing. Over time a spring can wear or break, leaving the door much harder to lift.
An unsuitable or changed setup
The spring arrangement needs to suit the door’s weight and configuration. Previous modifications or replacement panels are useful information when assessing the system.

Should both springs be replaced together?
That depends on the spring arrangement, condition, and service history. Ask the technician to explain whether replacing one or both is appropriate and what is included in the estimate. The decision should follow the inspection.
Can I use the opener with a broken spring?
Stop operating the door. The opener is not a substitute for the lifting support provided by the spring, and repeated attempts can place additional strain on the system. Keep the opening clear and arrange an assessment.
