Safety: Garage doors are heavy and spring/cable systems can be under significant tension. Do not loosen or disassemble high-tension hardware unless you are qualified to do so.
Grinding or Clicking
These sounds can involve opener drive components, rollers, hardware, or parts moving under abnormal resistance.
Scraping or Rubbing
Scraping can indicate track, roller, hinge, panel, or alignment problems.
Do Not Mask a Mechanical Problem
Lubrication can help appropriate moving points, but it should not be used to hide binding, broken, or damaged components.
