Q. Why does my automatic door keep opening?

The sensors on an automatic door are responsible for detecting motion and triggering the opening and closing mechanisms. If these sensors malfunction, they may detect motion when there is none, causing the door to open and close repeatedly.


Q. What do I do if my automatic door won’t close?

Check the toggle switch on the operator and ensure it is not on the “hold open” setting.

Check the sensor.

Check/clean the door’s track of dirt & debris.

If the issue persists, please call 905-458-1332 or email

You can reset your automatic door opener by resetting the control panel. Turn off the power for 20 seconds and then turn it back on.


Q. Can automatic doors be opened manually?

In the event of power failure or an emergency, automatic doors can function manually. Swing doors have a spring that will allow the door to open and close as normal.


Q. What is the difference between power-assisted door and automatic door?
