In Hanoi, NABCO automatic doors are increasingly common in hospitals, shopping malls, office buildings, hotels, and large-scale developments. With smooth operation, high safety standards, and durability that meets Japanese specifications, NABCO automatic doors are widely regarded as an optimal solution for spaces with heavy pedestrian traffic. However, even premium equipment cannot avoid technical issues after long-term operation with thousands of daily cycles. At that point, finding a professional NABCO automatic door repair service in Hanoi with in-depth knowledge of Japanese technology becomes more essential than ever. This article provides a comprehensive overview of NABCO automatic door repair services and effective solutions to protect the “smart entrance” of your building in a sustainable manner.
What are NABCO automatic doors and why is professional repair necessary?
Introduction to Japanese NABCO automatic doors
NABCO is a leading automatic door brand under Nabtesco Corporation (Japan), holding more than 50% market share in Japan and ranking among the world’s largest manufacturers in the fields of mechatronics and automation. Japanese NABCO automatic doors are researched and manufactured under stringent technical standards, ensuring high durability, precise operation, and maximum safety throughout their service life.
Thanks to their superior quality and long-term stability, NABCO automatic doors are widely installed in critical facilities such as hospitals, medical centers, airports, railway stations, shopping malls, office buildings, hotels, and high-end mixed-use complexes.
Why do premium automatic doors still require repair?
Despite their reputation for durability and quality, NABCO automatic doors are complex electro-mechanical systems comprising motors, control boards, safety sensors, sliding rails, rollers, and various mechanical components. When operating continuously over long periods, natural wear and unexpected faults are unavoidable.
Depending on specific conditions, doors may experience reduced sensor sensitivity, deviation from original technical parameters, mechanical wear, or issues caused by power supply instability and environmental factors. Therefore, periodic repair and maintenance of NABCO automatic doors are essential to ensure stable operation, user safety, and extended system lifespan.
Common problems with NABCO automatic doors
During operation, NABCO automatic doors may develop issues due to continuous use, environmental conditions, or component aging. Users should proactively contact automatic door repair services when noticing abnormal signs such as doors failing to open or close despite having power, unusual operational noise, slow opening and closing speed, inaccurate stopping points, unstable sensor performance, or sudden stoppages and intermittent operation.
Below are the most common issues encountered in practice:
Motor failure or motor not operating
NABCO motors are well known for their durability; however, after 7–10 years of continuous operation, bearings or reduction systems may wear out. When motor problems occur, the door may exhibit the following symptoms:
- Failure to open or close.
- Slow or jerky movement.
- Loud operational noise.
These issues are typically caused by motor wear, prolonged overload, or misalignment in the transmission system.
Sensor malfunction or no response
Sensors play a critical role in ensuring user safety and are constantly exposed to external environmental conditions. When sensors malfunction, the door may fail to detect pedestrians, open or close at incorrect times, or pose potential safety risks. This issue should be inspected and resolved promptly by qualified technicians.
Control board failure
The control board serves as the central unit that receives and processes all operational signals. When the board is affected by moisture, electrical short circuits, or faulty components, the door may operate erratically, intermittently, or stop functioning entirely.
Mechanical damage (rollers, pulleys, belts)
After prolonged use, mechanical components such as rollers, pulleys, and belts are prone to wear and aging. Without timely replacement, the door may become jammed, misaligned on the track, operate with increased resistance, and cause secondary damage to other system components.
Early detection and timely repair of NABCO automatic doors help prevent widespread damage, ensure user safety, and minimize long-term operational costs.

After identifying the root cause, technicians propose an appropriate repair solution, clearly outlining each repair item and associated costs.
Replacement of genuine components (if required)
In cases of severe component damage, replacing parts with genuine NABCO automatic door components is necessary to ensure compatibility and system longevity.
Testing and handover
After repair, the door is tested multiple times. Technicians verify sensor safety, opening and closing speed, motor smoothness, and recalibrate technical parameters before handing over the system to the client.
