Report what is visible from a safe position

Describe whether the cable hangs loose, the door sits unevenly or the fault followed an obstruction. Do not unwind it from a drum or release a bracket for a clearer photograph. A cable problem can be a consequence of another failure, so selecting a cable by appearance alone is premature.

Retain the assembly record

If an older installation record is available through the Palm Beach Gardens permit search, keep it with the equipment information. That record may help identify the original door, but later repairs and current damage still need inspection. Ask why each connected component is included rather than assuming a cable replacement renews the entire door.

Your questions

Can I open the door using the side with an intact cable?

No. Uneven support can create dangerous movement. Keep people away from the opening and tell the provider about any vehicle trapped inside.

Will both cables always need replacement?

The recommendation should follow the installed system, condition and manufacturer requirements. Have the technician explain the selected scope instead of assuming a universal rule.
