Wear and tear – this type of problem is inevitable. When a roller becomes too worn, it can come off the track and uproot the entire system.
Bent Rollers – Accidents and excessive pressure can cause the roller to bend which could lead to a potential break. If a roller bends, you won’t get the same smooth movements when opening and closing the door.
Interrupted Spins –A proper roller should spin freely on the shaft. When the roller gets to a point where it cannot do that, be sure to call a professional for a quick replacement.
Excessive Vibrations –It can be natural for certain types of rollers to give off some sort of vibration while in use. However, if it gets to a worrisome point, it may be time for a replacement.
