Common problems with automatic sliding doors
Doors won't close
Obstructed safety beams. These are safety sensors located internally or externally in the door frame which are designed to prevent the doors closing on objects or persons paused in the doorway. These can be one or two sets around ankle height and knee height, usually clear or black about 15mm diameter. If dirty, obstructed, in bright sun or poorly aligned, the doors will not close.
No 230v mains power to door operator. Doors will usually stay open or run at reduced speed (and may beep) depending on brand/model. Indicator lights on overhead movement sensors do not illuminate. Note some models will run sensors on battery backup.
Fire alarm activation or emergency door release switch activated.
Overhead movement sensors activated by swaying plants, signs, banners, decorations, etc.
Doors won't open
Mode switch not in correct position (auto).
Overhead sensor obstructed or damaged by vandal/insects/water.
Doors manually locked.
Doors operating slowly (and may beep)
No mains power.
Doors obstructed by stones, debris or mat. Doors will usually resume normal operation when obstruction removed and door can do full open/close cycle.
Doors slamming closed/open
Door travel has been obstructed by furniture or heavy object.
Mechanism or control fault.
Unusual or noisy operation
Check for stones, debris under doors. Loose/dirty floor guides (especially frameless glass doors).
Note. Switching off mains power to 'reset' unit only works on some older door operators as most modern units have battery backup systems.
