Spring and Cable Repair

Springs and Cables in Long Beach

These two parts fail more often than everything else on a garage door combined, and they fail in ways you can identify from the driveway.

The Spring

The springs carry the door’s weight. The opener only nudges an already balanced door, which is why a snapped spring stops everything: there is nothing holding the weight any more.

How to tell. Look at the shaft above the door. A torsion spring that has failed shows an obvious gap in the coil, usually a couple of inches, as if someone cut a slice out. Older doors with extension springs run a spring along each horizontal track instead, and a failure there is more dramatic because the spring can whip if there is no containment cable through it.

Why both get replaced. Both springs have taken the same number of cycles. When one goes the other is close behind, and a door running on one new and one tired spring lifts unevenly, drags in the track, and pushes the opener to make up the difference on every cycle.

Why we will not let you do it. A wound torsion spring holds a serious amount of energy. It has to be unwound and rewound with proper winding bars, seated, and the set screws torqued. Screwdrivers and lengths of rebar are how people lose fingers.

The Cable

Lift cables run from the bottom bracket up to a drum on each end of the shaft. They do the actual lifting as the drums wind.

How to tell. The door lifts crooked, one side leading the other, and then binds in the track. Or you can see a cable hanging slack, or frayed and fuzzy where it winds onto the drum.

Why it matters immediately. A door lifting crooked is putting all its load into a track that was not designed to take it sideways. Keep operating it and you bend track and twist a panel, which turns a cable job into a section job.

Where Long Beach makes it worse. Salt air in this city corrodes the cable from the inside of the strand. It looks fine, right up until it parts. We check the cables on every visit here regardless of what we were called for, because the coast earns that check.

The Visit

1. Disconnect the opener and take the door weight by hand.
2. Unwind the springs safely with winding bars.
3. Replace springs as a matched pair, sized to the measured door weight, or replace the cable set and re-seat both drums so they are timed together.
4. Rewind to the correct number of turns for the door height.
5. Balance test: lift to waist height by hand and it should hold position.
6. Reconnect and run both opener safety reversals.

Cycle Life

A standard spring is rated near 10,000 cycles, about seven years at four openings a day. High-cycle springs rated near 25,000 cycles cost more up front and are the right call on a busy door or a detached garage used as the main way in.
