Spring repairs involve stored tension and a complete door system—not simply swapping a visible part.
A spring is part of the balance system
A heavy door and its spring system must work together. A spring that looks similar is not automatically the correct replacement. The technician needs to assess the door and related hardware before choosing the repair approach.
Keep the area clear when something fails
A sudden bang, visible spring gap, or unusually heavy door can indicate a problem that needs assessment. Stop using the opener and keep people clear of the opening. Do not attempt to wind springs, release tension, or remove associated brackets and cables.
Ask what the repair covers
Request an explanation of the proposed spring work, related wear, and the checks planned afterward. Ask for product and labor terms in writing. Share the door size, any model information, and your location when contacting Bonita, but leave spring selection and measurements that require handling the system to the technician.
