Automatic doors make entering and exiting buildings so much easier—especially during cold Canadian winters or when your hands are full. But when your automatic door system suddenly refuses to close, it can be more than just an inconvenience. It can affect security, energy efficiency, and safety. If you’re dealing with this issue, here’s what you can do and why calling a professional should always be your next step.

Start with Simple Checks 

Before you panic, take a few minutes to do some basic checks. Many automatic door issues are caused by small things that are easy to overlook.

• Look for Obstructions: Check if something is blocking the door’s path. Even a small item, such as a leaf, rock, or piece of garbage, can trigger the sensors and prevent the door from closing. 

• Inspect the Sensors: Dirt, dust, or snow can block the sensors, making them think something’s in the way. Gently clean the sensor area with a soft, dry cloth. 

• Check for Power Issues: If there’s a power outage or loose connection, the system might not work correctly. Make sure your building has power and that the door’s switch is turned on. 

• Try Resetting the Door: Some automatic door systems have a reset button that can be used to resolve issues. Turn the system off for a minute and then turn it back on to see if the issue is resolved. 

These quick checks may temporarily fix the problem, but if the door still won’t close after that, it’s time to take it seriously. 

Understand What Might Be Causing the Problem

Automatic doors are complex systems that rely on sensors, control panels, and mechanical parts to function correctly. If the issue isn’t apparent, it could be related to one of the following: 

• Faulty Sensors: If the sensors are misaligned or damaged, the door may think there’s something in its path even when there isn’t. 

• Motor Problems: The motor that powers the door might be worn out or malfunctioning, preventing it from completing its closing cycle. 

• Electrical Issues: Damaged wiring or control boards can cause the system to behave unpredictably. 

• Mechanical Obstructions: Internal parts, such as rollers or tracks, can become jammed or bent, preventing the door from opening and closing smoothly. 

It’s not always easy to tell what’s wrong by just looking at it. That’s where calling an expert becomes essential. 

Why You Should Call a Professional Right Away

When your automatic door won’t close, it’s tempting to keep trying to fix it yourself. However, doing so can often exacerbate the problem. Modern door systems are built with sensitive components that can be damaged if mishandled. Here’s why it’s best to leave it to the pros: 

• Safety First: Automatic doors are heavy and move with force. Handling them without proper training can lead to injuries. 

• Prevent Further Damage: A quick DIY fix might seem to work at first, but it could cause long-term damage to the door’s sensors or motor. 

• Save Time and Money: Professionals can pinpoint the problem right away, preventing costly breakdowns in the future. 

• Ensure Compliance: Commercial automatic doors in Canada must meet specific safety standards. Only certified technicians can ensure your system meets those requirements. 

A door that won’t close properly isn’t just a minor problem—it can affect safety, comfort, and security. Once you’ve done the basic checks and it’s still not working, it’s time to call in the professionals.
