Signs Your Automatic Sliding Doors Need a New Sensor


It's common for commercial businesses to have automatic sliding doors, which are the type of doors that slide open automatically when someone approaches them. From an outside perspective, their ability to sense when people are nearby and when they aren’t can seem like magic. In reality, they use automatic sliding door sensors to determine when they should open and close. As one of the most common issues that cause automatic doors to fail, if the sensor isn't working correctly, the doors can start to malfunction. This means that your automatic door won’t open or close or start opening and closing at the wrong time. In this guide, we'll explain some of the signs your automatic sliding doors sensor is not working and needs to be replaced.


Automatic Door Troubleshooting 


The Door Isn't Opening or Closing

If customers are standing by the automatic sliding door and it's refusing to budge, it could be a sign of a bad sensor. The first thing you'll want to check, however, is the power supply. A blown fuse or popped circuit are two other reasons the door might not be working. Most doors will have two automatic sliding door sensors, one on the interior and one on the exterior side of your building. If people can leave your establishment without problem, but are having trouble entering, the exterior sensor is the one that’s failing. If people on both signs are having a hard time getting the door to open, it's more likely to be a power issue. It's rare to have both sensors fail at once. 


The Door Opens at Random

Your automatic sliding door is designed to open and close whenever someone is standing near it. If they're opening and closing for seemingly no reason, it could be a problem with the automatic sliding door sensors are not working. The first thing you'll want to check is whether there's something else that's triggering the sensor, such as a flying plastic bag, a wandering animal, or a large insect. If the door is opening repeatedly and there doesn't appear to be anything that's triggering it, call an expert. In some cases, the solution to your automatic door sensor not working involves cleaning or re-calibrating the sensors. If that doesn’t work and your automatic door keeps opening and closing, the sensors need to be repaired or replaced.


The Door is Shutting on Customers

Another sign your automatic sliding doors need a new sensor is that it’s starting to close too early. If your door is shutting prematurely, you should have the sliding door sensor replaced as soon as possible. A door that closes while something is passing through it is a major safety hazard. It can hit or close on customers and employees, causing injuries you could be held liable for.

Automatic sliding doors offer convenience and efficiency for building owners and maintenance managers. Understanding the terminology associated with these doors can help in making informed decisions about installation, maintenance, and repairs. This glossary of automatic sliding door terminology will help you understand what to expect and how to manage these systems effectively. 1. Automatic Sliding Door An automatic sliding door operates without the need for manual intervention. These doors open and close in response to detected movement, offering seamless access for pedestrians. They’re commonly found in commercial buildings, such as shopping malls, airports, and office complexes, providing convenience and improved energy efficiency. 2. Motion Sensor Motion sensors play a crucial role in the operation of automatic sliding doors. These devices detect the presence of individuals approaching the door and trigger the opening mechanism. There are various types of motion sensors, including infrared sensors, microwave sensors, and photoelectric sensors. Each type has unique advantages relevant to the application and environment. 3. Activation Device An activation device is any tool or technology that initiates the opening of an automatic sliding door. While motion sensors are common, other activation devices include push buttons, key fobs, and swipe cards. Building owners and maintenance managers should choose the right activation device based on accessibility needs and expected foot traffic. 4. Door Operator The door operator is the heart of the automatic sliding door system. This motorized mechanism controls the movement of the door panels. High-quality door operators ensure smooth and reliable operation, minimizing wear and tear on the door components. Regular maintenance of the door operator is crucial to prevent unexpected breakdowns and maintain safety. 5. Safety Sensor Safety sensors are an essential feature of automatic sliding doors. They prevent the doors from closing on individuals or objects by detecting any obstruction in the door's path. If something triggers the safety sensor, the door will reverse or halt its movement. These sensors protect users and comply with safety regulations, making them a vital component of the door system. 6. Automatic Door Repair Despite the advanced technology of automatic sliding doors, they can still experience issues. Regular maintenance and prompt automatic door repair can help prolong the lifespan of the doors and maintain their efficient operation. Building owners and maintenance managers should develop a proactive maintenance schedule to address potential problems before they escalate into costly repairs. This glossary of automatic sliding door terminology provides a foundation for discussing installation, maintenance, and repairs related to automatic sliding doors. By familiarizing yourself with these terms, you can ensure smooth operation and address any issues that may arise. Embracing this knowledge will lead to a safer and more efficient environment for all building occupants. As always, reach out to Pacific Entrance today for commercial automatic door repair service.
