The automatic garage door gets to one point while closing and then reverses? The track is most likely blocked or bent. A check will show the precise cause of the problem. Blockage caused by pebbles and dirt should be removed carefully to prevent damage. A bent track can usually be straightened with a set of special repair techniques. However, if it’s bent close to the point of breaking, it should be replaced with a new one of the same size. Generally, the thicker these components are the less likely they are to get damaged or broken. Sometimes the vertical and horizontal track sections can get misaligned and cause door malfunction. After the proper adjustment, the bracket bolts should be tightened to ensure that the sections will stay in place.
One of the most important tasks is the testing of the safety sensors. Ideally, they should be tested every three or four months. This will help to keep the door’s safety optimal at all times. The whole system requires full maintenance at least once a year. A detailed inspection will reveal damaged, broken and worn parts requiring replacement. The opener’s force and the spring system’s tension should be assessed with special tests. When adjustment is required, it has to be perfectly accurate. The panels and the dirty hardware and electronic components require cleaning. Lubrication is reserved for the torsion spring, metal rollers and all areas where there's a chance of friction (between two metal parts). While wood doors require repainting every year, steel ones can be repainted every couple of years.
