Customer Problem
The homeowner heard a loud bang from the garage and found the sectional door wouldn't budge — the opener hummed and gave up. On arrival the cause was obvious: a clean break in the torsion spring above the door, with the coils sitting apart on the shaft. With the spring gone, the opener was being asked to lift the full weight of the door on its own.
- Loud bang, then the door refused to open
- Visible gap in the torsion spring coils above the door
- Opener straining and stopping — a safety cut-out doing its job
Inspection & Diagnosis
Torsion springs on a two-spring door are wound the same day and cycle together, so when one snaps its partner is almost always weeks from doing the same. Replacing only the broken one would leave a mismatched pair and a second call-out — which is why we quote springs as a matched set on doors like this. The rest of the hardware — cables, drums and bearings — checked out fine.
- Spring failed at the end of its rated cycle life, not from damage
- Second spring the same age — replaced as a pair
- Cables, drums and centre bearing inspected and retained
Solution
We fitted two new high-cycle torsion springs sized to the door's weight, wound them to spec, then balanced the door so it sits still at half height by hand — the test that tells you the springs are doing the lifting, not the motor. Finally the opener's force limits and safety reversal were re-checked and the moving parts lubricated.

- Opener force limits and auto-reverse re-tested

Frequently Asked Questions
Paired torsion springs are the same age and have done the same number of cycles, so the survivor is close to failing too. A new spring next to a tired one also unbalances the door and overworks the opener. Replacing the pair costs far less than two separate call-outs a few weeks apart.
