7 Signs of a Broken Garage Door Spring (and Why You Should Not Lift the Door)

The visible gap in the coil

This is the definitive test. Look at the torsion spring mounted on the shaft above the door opening. An intact spring is a continuous, tightly wound coil. A broken one has an obvious two- to three-inch gap where it separated. On doors with extension springs running along the horizontal tracks, look for a spring that has gone slack or come apart.

You heard a bang from the garage

Homeowners often describe it as a gunshot or something heavy falling. A torsion spring stores an enormous amount of energy, and when the metal finally fatigues, that energy releases in a fraction of a second. If the door then refused to open, you already have your answer.

The opener strains, then stops

Openers have force limits designed to protect the motor. With the springs gone, the opener is being asked to lift the door's entire weight — often 150 to 300 pounds — and it will hum, strain, move an inch or two and give up. Repeatedly trying will burn out the gear or the motor, adding an opener repair to your spring bill.

The door is crooked or drops fast

If one of a pair of springs broke, the door may still move but hangs unevenly and comes down faster than it should. A door that slams rather than settles is unbalanced and unsafe.

The door is extremely heavy by hand

Disengage the opener with the emergency release and try to lift the door manually — carefully, and only a few inches. A properly balanced door on healthy springs lifts with roughly ten pounds of effort and stays put where you leave it. If it feels like deadlifting, the springs are gone.

Cables have gone loose or unwound

When spring tension disappears, the lift cables slacken and often unwind off their drums. Loose or tangled cable is a strong secondary confirmation, and it means the cable will need re-seating alongside the spring work.

Gaps at the top or a bowed top section

A door left hanging on a broken spring sometimes shows a visible gap at the top of the opening or bowing in the top panel where the opener arm has been pulling against dead weight.

Why replacing it yourself is a bad trade

Winding a torsion spring requires proper winding bars and correct technique. A slipped bar under load is one of the most common serious DIY injuries in home maintenance, and the spring must also be correctly sized to the door's weight to work at all. The parts cost is a small share of the job; the tooling and the risk are the rest.
