Has anyone dealt with sliding doors that suddenly resist opening or closing smoothly in a residential or commercial setting? I am troubleshooting an issue where the door feels heavy, jerky, and inconsistent, especially halfway through its movement.
After basic cleaning and lubrication, the problem persists, and I am starting to suspect an obstructed track causing the sliding doors to become difficult to open rather than worn rollers. What diagnostic steps should I take next, and are there common debris or alignment issues I might be overlooking?
Any advice on repair versus replacement, preventive maintenance, or safety concerns would be appreciated.
