Automatic Sliding Door Maintenance and Troubleshooting Guide

Automatic sliding doors offer convenience, accessibility, and a touch of modernity to various establishments, including shopping malls, hospitals, airports, and commercial buildings. These doors use sensors and motors to open and close automatically, providing a seamless entry and exit experience for users. To ensure the smooth functioning and longevity of your automatic sliding doors, regular maintenance and timely troubleshooting are essential. In this comprehensive guide, we will explore the key aspects of automatic sliding door maintenance and address common issues you may encounter.

Regular Maintenance

a. Cleaning and Lubrication: Regularly clean the door’s tracks, sensors, and glass panels using mild detergent and a soft cloth. Additionally, lubricate the door’s moving parts, such as rollers and tracks, with a recommended silicone-based lubricant to reduce friction and wear.

b. Sensor Calibration: Periodically check and calibrate the door’s sensors to ensure they are accurately detecting approaching users. Improper sensor alignment may result in delayed responses or false detections, compromising the door’s efficiency and safety.

c. Inspection of Electrical Components: Inspect the wiring, control panels, and power supply for any signs of damage or loose connections. Electrical issues can lead to malfunctioning doors or pose safety hazards.

d. Safety Features Testing: Test the safety features, such as presence sensors, emergency stop buttons, and safety beams, to confirm they are functioning correctly. These features are crucial for preventing accidents and ensuring user safety.

e. Rollers and Track Alignment: Check the rollers and track alignment regularly to ensure they are clean, free of debris, and functioning smoothly. Misaligned rollers can cause the door to veer off its track, leading to potential damage and malfunctions.

Troubleshooting Common Issues

a. Door Not Opening or Closing: If the door is not responding to sensor inputs, check the power supply, sensor alignment, and connections. Ensure that the power source is active, and sensors are unobstructed and calibrated correctly.

b. Slow or Partial Opening/Closing: Inspect the rollers, tracks, and hinges for obstructions or damage. Also, check the lubrication level and apply more if needed. Misalignment may also cause slow or partial movements.

c. Door Slamming or Jerking: If the door is jerking or slamming shut, it could be a sign of misaligned tracks or damaged rollers. Adjust or replace the affected components as required.

d. Unusual Noises: Strange noises during door operation may indicate worn-out or damaged components. Thoroughly inspect the door’s mechanical parts, and replace any worn or broken elements.

e. Door Not Closing Completely: Misalignment or debris in the tracks can prevent the door from closing fully. Clean the tracks and check for any obstructions to resolve the issue.

Professional Maintenance

While regular maintenance can significantly extend the lifespan of your automatic sliding doors, it’s advisable to schedule periodic inspections and maintenance with a qualified technician. Professional service ensures that all safety features are working correctly, electrical components are in good condition, and any potential issues are addressed before they escalate.


Automatic sliding doors provide a convenient and efficient way to manage foot traffic while offering accessibility to everyone. Regular maintenance, cleaning, and troubleshooting are essential to ensure these doors operate smoothly, quietly, and safely. By following the maintenance guidelines and promptly addressing any issues, you can prolong the life of your automatic sliding doors and maintain a positive user experience in your establishment. If you encounter complex or recurring problems, seek assistance from professional technicians who specialize in automatic door maintenance and repairs.
