Quick Answer
An automatic door that does not detect approaching users may have a dirty or misaligned activation sensor, a limited detection zone, damaged wiring, a failed push plate or a control problem. Check whether other activation methods work and keep the sensor area clear. If detection is inconsistent or users must stand unusually close before the door opens, professional sensor testing and adjustment are recommended.
An automatic door should detect approaching users early enough to open smoothly and safely. If people must stop, wave or move unusually close before the door responds, the activation system may need attention.
Common Reasons an Automatic Door Does Not Detect People
- Activation sensor is dirty or obstructed
- Sensor has moved out of position
- Detection zone is too limited
- Push plate or touchless control is not working
- Sensor wiring is damaged
- Operator control has developed a fault
Check Whether Other Activation Methods Work
If the wall button or push plate works but the motion sensor does not, the problem may be limited to the sensor or its control. If no activation method works, the operator, power or access-control system may require inspection.
Sensor Position Matters
Automatic door sensors must be positioned so they detect normal approach paths. Accidental impact, building changes or nearby objects can affect the detection area.
Do Not Reduce Safety to Improve Activation
Sensor settings should not be changed in a way that compromises safe operation. Activation and presence detection should be tested together.

Frequently Asked Questions
Why does my automatic door only open when I get very close?
The activation zone may be too limited, the sensor may be misaligned or the sensor may be partially obstructed.
Why does the push plate work but the motion sensor does not?
The sensor or its wiring may have a fault while the operator itself is still functioning.
Can automatic door sensors move out of position?
Yes. Impact, vibration or maintenance work can affect sensor position and detection coverage.
When should automatic door detection be professionally tested?
Arrange testing when detection is inconsistent, users must stand unusually close or one activation method stops working.
