Garage Doors decision guide
Reviewed and updated September 24, 2026
Do not operate the door when one of its springs has broken. The second spring is not permission to keep using the system. DASMA’s safety guidance recommends addressing both springs when one of a pair breaks, but a technician still needs to verify the correct arrangement and parts for the actual door.
Prevent further operation and arrange an on-site assessment by a trained garage-door technician, providing the door position, labels, and failure history.
Residential counterbalance systems and professional service boundaries
Choose a state to make the geographic boundary explicit.
A ZIP code does not prove compatibility, performance, price or service acceptance.
Stop using the wall control, remote, and manual release. Keep people, pets, and vehicles away from the opening, especially if the door is partly open or its position appears unstable. Do not try to lift the door, restrain it, reconnect hardware, or touch springs, cables, bottom fixtures, brackets, or supports. Counterbalance work belongs to trained door-system personnel because the connected hardware can store substantial force.
From a safe position, record the door and opener labels, the door position, the time of the failure, and whether a loud bang or change in movement was noticed. Photograph only what is visible without entering the travel path or moving parts. Do not use the surviving spring’s appearance to estimate its remaining life. The presence of two springs does not establish that the door can be moved safely with one spring broken.
Tell the technician that one spring in a paired arrangement appears broken and ask the technician to confirm the actual system, the correct parts, and the condition of connected hardware. A general recommendation cannot substitute for identifying the installed door. DASMA recommends addressing both springs when one of a pair breaks, but that statement is not an installation instruction or a universal parts specification. The technician must confirm what applies to this door and explain the proposed scope.
Notice next: Prevent further operation and arrange an on-site assessment by a trained garage-door technician, providing the door position, labels, and failure history.
Residential counterbalance systems and professional service boundaries
These records narrow the request; they do not prove compatibility, performance or a failed part.
No. Prevent further operation and keep the opening clear until a trained technician assesses the system.
No. The technician must verify the door, spring arrangement and correct parts from the actual system.
Provide the door position, visible labels and failure history without touching the connected hardware.
Industry guidance does not inspect this two-spring door or select its replacement spring. Product instructions and the serving authority control applicability.
This answer does not identify the replacement part or approve further operation; the trained assessment must use the actual door and spring arrangement.
No local result, price, provider availability, offer, phone or routing claim is made.
