Spring Symptom Triage
Spring Symptom Triage: the decision explained before the repair, so the right service page is opened first.
What this guide answers
Most garage door symptoms point to several possible causes, and guessing wrong wastes a visit. A loud bang is usually a spring, but a heavy door can be a spring, a cable or a seized roller, and a door that reverses is often a sensor, not a spring at all.
This guide separates symptoms by cause, so the right service page is opened and the right problem is described when calling. It is a triage guide, not a repair manual: it narrows the cause and tells you what to stop doing, not how to fix the part.
Details that matter
- Loud bang plus a visible gap in the coil above the door, or a door that suddenly feels far heavier: a broken torsion spring is the most likely cause. Stop using the opener and leave the door where it is.
- Door lifts crookedly, one side lagging, or a spring hangs loose along a track: a broken or stretched extension spring, or a cable that has jumped its drum or pulley. Do not force the door level.
- Door jerks, squeaks or grinds but still moves: worn rollers, dry hinges, loose hardware or a bent track section are more likely than a spring. Lubrication helps dry parts, but a seized roller or cracked hinge needs replacement.
- Door reverses on closing, or only closes while the wall button is held: a safety sensor fault is the most likely cause, usually alignment or a dirty lens, not a spring or motor fault.
- Opener hums or clicks while the door does not move: test the door by hand with the opener disconnected. A heavy door points to the spring; a free-moving door points to the opener gear or logic board.
- Door will not stay open, or drifts from halfway: a balance problem, usually spring tension loss or uneven cable tension, rather than an opener fault.
How to use this guide
- Note the exact symptom: sound, heaviness, crookedness, reversing, or drift, and when it started.
- Test the door by hand with the opener disconnected, only if the door is not broken, jammed or hanging crooked, and never stand under it while testing.
- Match the symptom to the cause table in this guide, and open the service page for that cause.
- Stop using the opener if the door is heavy, crooked or jammed, and keep clear of a door hanging off its track.
- Describe the symptom, the hand test result and the door's spring system when calling, so the right parts and repair are planned.
What to check first
Check the coil above the door for a gap, the tracks for a loose spring or jumped cable, the sensors for alignment and clean lenses, and the door's balance by hand, in that order.
What goes wrong if the problem is delayed
Guessing the cause and running the opener anyway is how a spring problem becomes an opener problem, and how a cable problem becomes a track problem. Triage first, then the opener stays off until the cause is known.
What this guide is, and is not
Included: This guide covers symptom triage only. It is not a repair quote and does not teach spring winding or tensioning.
Not included: No price or arrival time is stated on the Spring Symptom Triage page, because neither has been supplied for this business. No DIY repair instructions for tensioned parts are given on this site.
Questions readers ask
My door makes a loud bang but still opens. Is it safe to keep using?
No. A bang often means a spring broke, and a door running on a remaining spring or on the opener alone is unbalanced and can fail suddenly. Stop using the opener and have the spring state checked.
How do I know if it is a sensor problem or a spring problem?
A sensor problem usually shows as reversing on closing or closing only while the wall button is held, with the door otherwise moving normally. A spring problem shows as heaviness, crookedness or drift when the door is moved by hand.
My door is noisy. Does that mean the spring is failing?
Not necessarily. Grinding, squeaking and rattling usually come from rollers, hinges, loose hardware or track issues, while spring failure is more often a bang, heaviness or drift. Noise triage points to the moving joints first.
