Lyndhurst Torsion Spring and Cable Repair

Why springs and cables are checked together

On a torsion-spring door, the spring turns a shaft above the opening. Drums at the ends of that shaft take up the lift cables. If a cable leaves its drum or the hardware shifts, one side of the door may move differently from the other. The photograph shows the components involved, but a technician needs to inspect the actual door to identify the cause.

Details to share before a Lyndhurst visit

Tell us whether the door is crooked, whether a cable looks loose, and whether you heard a bang before it stopped working. Mention any recent repair or impact you know about. Describe what you have already seen; do not operate the opener again to demonstrate the fault.

Leave the spring, drums, cables, and bottom brackets alone. Do not try to wind a cable back onto its drum or turn the spring hardware. If the door is raised, keep the opening clear and use another entrance. A free estimate follows an assessment of your door, rather than an assumption that every visible cable problem needs the same repair.
