When Activated Door Doesn't Open Fully and/or Lights Flash when ClosedUpdated 6 hours ago

This article concerns the following AutoSlide behavior:

1. Upon initial activation, the door opens but abruptly stops (usually stopping short of the full opening width or physically touching the door stop on the open jamb side) and reverses back closed immediately (even if the OpenTIme is set to a value greater than zero seconds).
2. After approximately five such activation attempts, the AutoSlide displays flashing mode lights and is unresponsive in the closed position.

Causes and Diagnosing

This behavior is usually caused by an increase in resistance when attempting to open. This resistance can be caused by multiple factors, including:

• the AutoSlide track being too tight to the motor gear at a certain section of the door's opening path
• the door itself binding at a certain spot
• excess drag at the bottom of the door compared to the top of the door, causing the panel to tilt when opening.

The extra resistance trips the AutoSlide's safety reversal, causing it to abruptly go back to the closed position. If this obstruction is detected five times in a row, the system will error in the closed position with all four mode lights flashing. The system needs to be power cycled to clear the error (or the mode button of the system held down for about 10 seconds).

An easy way to tell if this issue is occurring is to set the OpenTime in your system to the maximum setting, then to activate the system to open the door. If the system ignores the OpenTime and immediately and abruptly closes, it signals that the system is encountering an increase in resistance while opening.

Troubleshooting and Resolving

It is advised to perform a drag test while the system is powered off.

1. With the system off, manually open the door by just an inch.
2. Using only two fingers, push the door open at the same height as the AutoSlide system (not at the door handle).
3. Push the door open at a steady constant pace, feeling for any increase in drag or binding.
4. Repeat this process for closing the door, and repeat steps 3 and 4 as needed.

This should help identify if a bind is occurring. If the bind seems to be coming from the AutoSlide track being too tight to the gear, the screws holding the AutoSlide track to the door at that section may need to be adjusted to reduce pressure.

If the bind seems to be coming from the door itself, it is recommended to contact your door contractor to get the door serviced.

• A dry lubricant (such as an aluminum or silicone based lubricant) may help reduce drag if sprayed along the door's bottom track; be sure to vacuum and clean the door track prior to doing this.
• Raising the door panel using its height adjustment screws may also be necessary. Note that the AutoSlide track may need to be reinstalled if raising the door panel.

If it is uncertain if the bind is coming from the AutoSlide system or the door itself, it is recommended to uninstall the AutoSlide system from the door and repeat the drag test above.
