Are Repair Services Available for Out-of-Warranty Automatic Door Sensors?

Automatic door sensors play a critical role in ensuring safe, efficient, and user-friendly access to commercial, industrial, and institutional facilities. Over time, even high-quality sensors may require servicing due to environmental exposure, mechanical wear, or electrical faults.

A frequent question among customers is whether repair services are available for sensors that are no longer covered by warranty. This article provides a clear and detailed response, outlining the available support options and the advantages of engaging with a professional manufacturer.

1. Understanding Warranty Limitations

Most automatic door sensors are sold with a standard limited warranty, typically ranging from 12 to 24 months, depending on the product model and usage conditions. This warranty generally covers:

Manufacturing defects

Component failure under normal operating conditions

Product replacement or repair at no additional cost

Once the warranty period expires, customers may still require technical support, especially for critical entry points such as hospitals, airports, shopping centers, or logistics facilities, where operational downtime must be minimized.

2. Post-Warranty Repair Services: What We Offer

At Qinuo Electronics Co., Ltd., we recognize the importance of continued product support even beyond the warranty period. Our post-warranty repair services are designed to help customers extend the lifecycle of their sensor systems and reduce total cost of ownership.

Available Services Include:

Component-level diagnostics and troubleshooting

Sensor recalibration and firmware updates

Replacement of internal modules or optical components

Mechanical housing repair or replacement (if applicable)

Upgrade options to current-generation models at discounted rates

All repairs are conducted by trained technicians using genuine OEM parts to ensure compliance with performance and safety standards.

3. Repair vs. Replacement: A Practical Assessment

In some cases, repairing an outdated sensor may not be cost-effective or technically viable. Our technical team performs a full evaluation and provides a detailed quotation before proceeding with service. Customers will be informed whether:

The unit is repairable

The cost of repair is justified versus replacement

A new-generation sensor with enhanced features is recommended

We support a wide range of sensor models, including microwave sensors, active infrared sensors, laser sensors, and hybrid detection systems used in sliding, swing, and revolving doors.

4. Global Support and Logistics

Our repair service is available through:

Direct factory support at our manufacturing and R&D facility

Authorized service partners in key global regions

Spare parts supply for certified technicians and installers

Customers can initiate a repair request by contacting our support team via our service page. We offer:

Quick turnaround times

Transparent pricing

Technical documentation for traceability

5. Preventive Maintenance and Sensor Lifecycle Planning

To reduce the need for unexpected repairs, we recommend scheduling routine sensor maintenance every 12–18 months, particularly in high-traffic environments. Preventive maintenance includes:

Optical lens cleaning

Sensitivity testing

Parameter adjustment

Power supply inspection

Our team also offers sensor audits and site-specific lifecycle management planning for enterprise customers.

Conclusion

Yes, repair services are available for out-of-warranty automatic door sensors. At Qinuo Electronics Co., Ltd., we are committed to long-term customer satisfaction and operational reliability.

Why Your Automatic Door Doesn't Fully Close – Causes and Solutions for Gaps and Sealing Issues

Automatic doors are essential in modern buildings, offering convenience, efficiency, and enhanced security. However, one common issue faced by many users is the door not closing completely. This can result in visible gaps, poor sealing, energy loss, and compromised safety. If you're experiencing this problem, you're not alone. In this article, we’ll explain the key causes and practical solutions to help you restore the full functionality of your automatic door. Common Reasons Why Automatic Doors Don't Fully Close Sensor Malfunction or Misalignment Automatic sliding doors rely on sensors to detect movement and control the opening and closing cycle. If the sensor is misaligned or malfunctioning, it may misinterpret the surroundings and stop the door prematurely, leaving a gap. Obstructions in the Door Track Dirt, debris, or foreign objects in the track can obstruct the door’s movement, preventing it from fully closing. Even small particles can cause resistance that affects al...

What is the typical lifespan of automatic door infrared sensors, and when should they be replaced or upgraded?

Automatic door infrared sensors are vital components in modern building access systems, offering convenience, safety, and energy efficiency. These sensors are designed to detect the presence of individuals or objects and trigger the door's opening and closing. However, like any technology, they have a finite lifespan. In this article, we will explore the typical lifespan of automatic door infrared sensors and when they should be replaced or upgraded to ensure optimal functionality and safety. The Lifespan of Infrared Sensors The typical lifespan of automatic door infrared sensors can vary based on several factors, including the quality of the sensors, environmental conditions, and the level of use. However, on average, infrared sensors are expected to function reliably for approximately 5 to 10 years. Factors Affecting Lifespan 1.  Quality and Durability: High-quality sensors made from durable materials tend to have a longer lifespan. Cheaper or poorly constructed sensors may wear ...
