The Signs of a Broken Torsion Spring

A door that lifted with one finger last week and will not budge today has almost certainly lost its counterbalance. The repair notes at Garage Door Repair Long Beach CA Adams Bev Group open with this fault because it is the one that turns a working garage door into a two hundred pound wall, and because it is the fault most often misread as a dead motor. Long Beach garages sit close enough to the water that spring life runs shorter here than it does inland.

What the Counterbalance Does

A torsion spring is wound above the header and stores energy as the door comes down. On the way up it gives that energy back, which is why a correctly set door feels almost weightless in the hand. The opener is not a lifting machine. It is a guide with a small motor, and it is sized on the assumption that the spring is doing the work.

The Three Signs You Can Check From the Floor

The first is a visible gap. A wound spring is a continuous coil; a failed one shows a two inch break with the ends pulled apart. The second is a bang, which people describe as a gunshot in the garage overnight before finding the door dead in the morning. The third is a door that lifts about a foot, stops hard, and sags back down when released.

Why the Opener Gets Blamed

With no counterbalance the opener meets a load it was never designed to carry. It will strain, trip its force setting and reverse, or hum and do nothing at all. Replacing the operator at that point buys an expensive machine that will fail the same way within a month. Check the spring before anyone quotes you a new unit.

Do Not Pull the Release Under Load

The red cord disconnects the door from the trolley. Pulled while the door is up and the spring is broken, it hands the entire unsupported weight to whoever is holding the cord. If the door is open and the counterbalance has gone, leave it open, keep people and cars out from under it, and clamp a locking plier onto the track below the bottom roller so it cannot run down.

Why This One Is Not a Home Repair

Winding a replacement takes calibrated bars, the right inside diameter and wire gauge, and a feel for how many quarter turns the door wants. A bar that slips comes out of the cone at speed. On a two spring door both get changed together, because a matched pair that has run the same number of cycles will not stay matched for long once one of them is new.

What Gets Checked at the Same Time

A spring visit is the right moment to look at the cable, the drum seating and the end bearing plate, since all three carry the load the spring releases. A frayed cable found during a spring change costs a few dollars to swap and prevents the crooked door that a snapped one causes. The balance is then set by hand before the opener is reconnected.
