Automatic sliding doors are a common feature in many buildings across Canada, including offices, hospitals, malls, and residential complexes. They make entry and exit simple and hands-free, but like any automated system, they can sometimes malfunction or stop responding. When that happens, knowing how to reset your automatic door safely can make a big difference.

However, it’s important to remember that resetting should always be done with caution. The wrong move can cause damage or safety issues. Here’s a guide to help you reset your door properly—and when to call a professional. 

Why Automatic Sliding Doors May Need a Reset

Automatic sliding doors rely on sensors, control panels, and motor systems to function smoothly. Sometimes, even a minor disruption can throw the system off balance. Here are some common reasons a reset might be needed:

• Power interruptions: After a power outage or surge, the system might not restart correctly.
• Sensor errors: Dirt or misalignment can cause the sensors to stop communicating with the door controller.
• Obstructions: If something blocks the door’s path, the system may freeze for safety reasons.
• System updates or adjustments: Maintenance or changes to the control unit may require a manual reset.

Knowing what caused the issue helps you decide if a reset is enough—or if you need professional automatic door service & repair.

Steps to Safely Reset an Automatic Door

Resetting an automatic door isn’t the same for every model, but most systems follow similar principles. Always check your manufacturer’s manual first. If you’re unsure, it’s best to call a technician. Here’s a general process you can follow safely:

1. Ensure the area is clear: Make sure no one is standing near or walking through the doorway. Automatic sliding doors can flick during a reset.
2. Turn off the power: Locate the power switch, often found near the control box or breaker panel. Turn it off to cut power to the door and wait at least 30 seconds before turning it back on.
3. Check for visible obstructions: Look for debris, dirt, or ice buildup around the tracks or sensors. Remove anything that could block movement.
4. Turn the power back on: After waiting, switch the power back on. The door system should begin its startup cycle. Some doors may beep or flash indicators as they reset.
5. Test the sensors: Stroll toward the door to trigger the motion sensors. If the door opens and closes smoothly, the reset is likely to have worked.

If the door still doesn’t respond, avoid trying to disassemble anything. It’s time to call a professional door automation technician.

Keep Your Automatic Door in Good Working Order

Regular maintenance is the best way to prevent sudden breakdowns. Schedule routine inspections to ensure your doors operate smoothly and that minor issues are identified and addressed promptly. Here are a few simple habits that help:

• Keep sensors and door tracks clean.
• Watch for unusual sounds or movements.
• Don’t ignore slow or hesitant door responses.
• Get a professional inspection at least once a year.

Consistent maintenance from a reliable automatic door service & repair provider ensures your doors stay safe, efficient, and compliant.
