Spring Replacement
The torsion spring on the shaft above the door does the lifting. The opener only guides the door up and down.
When a spring breaks you usually hear a bang from the garage. After that the door lifts a few inches and stops, or the opener strains and quits. Older and lighter doors use extension springs that run along the horizontal tracks instead.
What the job includes
- New springs wound and set for the weight of your door
- Lift cables, cable drums and bottom brackets checked
- Door balanced so it stays put when lifted halfway by hand
- Opener reversing sensors tested before we leave
