Noise during closing normally points to worn carrier wheels, a dry or dirty guide rail, a loose belt or a floor guide full of grit. A leaf that has dropped slightly on its hangers can also scrape the frame. We clean the rail and track first, then check wheel wear, belt tension and leaf alignment. Spraying random lubricant on the rail often attracts more dust, so we avoid it unless the part calls for it.

In many cases yes, but it depends on the door leaf, frame and hinges. The door must open freely by hand, be strong enough to carry the drive, and meet the safety needs of the opening: sensors, closing force and, in some buildings, a way to disable the drive in an emergency. We inspect the door on site, tell you what is needed and what would need replacing, and only then recommend an operator.

The radar sensor above the door is tuned to detect movement. Slow walkers, children and wheelchair users can fall below its threshold or enter its field late. The sensor may also be aimed too high, covered in dust, or set for a narrow field. We adjust the detection area, test with real walking speeds and, where needed, add a presence sensor so the door reacts to people standing still near the opening.

We open the header and inspect belts, carriers, wheels, the guide rail and the motor. We clean the floor guide, test the controller response, check sensor aim and range, and run the safety tests on closing and reversing. Glass fixings, seals and any locking function are checked as well. You get a note of anything worn so you can plan repairs. A busy shop entrance is usually worth visiting at a quieter time of day.

Most automatic sliding glass door operators (including common commercial brands) drive the door leaf with a toothed drive belt. A belt that has stretched or has worn or missing teeth causes the door to move unevenly, slow down partway, or make a slapping or ticking sound as it opens and closes.

A loose belt can sometimes be re-tensioned, but a cracked or frayed belt should be replaced before it snaps, which would leave the door stuck. We carry belts to match common sliding door operators and check the drive pulley for wear at the same time.

The sensor above an automatic sliding glass door uses motion or presence detection to open the door and to stop it closing on someone standing in the doorway. A sensor that misses people, triggers randomly, or stops responding is usually dirty, misaligned after a knock, or has a failing connection to the control unit; direct sunlight or reflective flooring can also confuse some sensor types.

We clean and realign the sensor first, then check its wiring and settings at the controller, and replace the sensor itself only if it still will not detect reliably.

The door leaf of an automatic sliding glass door hangs from wheels (rollers) running in an overhead track. Constant daily cycles wear the wheel bearings and can flatten the wheel surface, which shows up as the door sagging, dragging on the floor guide, or moving with a bump instead of smoothly.

We replace the wheels and check the overhead track for wear or debris at the same time, since a worn track shortens the life of new wheels too.

A radar sensor can be set off by movement outside the door, a swaying sign, reflections or dirt on the lens. It can also be misaligned after cleaning or an impact.

Qasar Al Neil Automatic Doors checks the sensor, adjusts its detection area and tests the door to make sure it opens only when someone is approaching.
