Safety: Garage doors are heavy and spring/cable systems can be under significant tension. Do not loosen or disassemble high-tension hardware unless you are qualified to do so.
Signs of Spring Trouble
A loud snap, a visible gap in a torsion spring, a door that lifts only a few inches, or a door that suddenly feels much heavier than normal can point to a spring-system problem.
Why Spring Work Needs Care
Garage door springs store substantial mechanical energy. Adjusting or replacing high-tension spring components is not a casual DIY repair.
Check the Whole Lift System
Spring problems can also affect cables, drums, rollers, and opener performance. A proper repair should account for how the complete door moves after the spring issue is addressed.
