Dust Events and What They Do in One Afternoon
A haboob does damage in hours that ambient dust takes years to do.
A wall of blowing dust drives fine sand into the track under pressure, films both photo-eye lenses, and packs the seal line. The practical consequence is a door that will not close that evening and an owner who assumes the opener has failed. After a significant dust event, wipe both lenses, sweep the bottom track out and check the seal line before operating the door repeatedly - running it with packed sand in the track is what wears the rollers.
