Signs a garage door spring needs replacement

Amarr says broken or worn springs make the door heavy and put an extra load on the opener. Chamberlain notes that weak or broken springs can leave a door that feels unusually heavy, will not stay open, or falls quickly, and describes these as indications of a spring problem. Clopay says a broken spring can produce a loud bang that sounds like a car backfiring.

Chamberlain's guidance for a door that behaves this way is not to force it but to stop and contact a professional, because a door with a failing spring can fall without warning.

Garage doors use one of two spring types. Torsion springs mount on a shaft above the door and are contained on that shaft; extension springs run along the horizontal tracks and, per DASMA, are contained by a cable through the centre of the spring. Both counterbalance the weight of the door. This is for identification only; DASMA recommends that a pair of springs be replaced at the same time by professionals.

DASMA states that springs and spring hardware are under high tension, and that removing, repairing, or adjusting springs or related parts must be done by a trained door systems technician using proper tools, because of the danger involved. This is not a do-it-yourself repair. Experts Garage Door provides broken spring repair in West Orlando, with a free on-site estimate.
