Automatic sliding door not working properly

Hello!

Sometimes the power sliding door controller gets confused and thinks there is something blocking the door travel path, when it may actually be encountering increased resistance due to friction.

When you open the door, you can try to gently assist the door past the spot where it has been stopping and reversing. If this helps, then some of the door components and/or track may need servicing.

Excess friction can be caused by corrosion, rust, dirt, or debris in the sliding door rollers, bearings, or pivot points.

This repair guide gives you an idea of what is involved if you need to remove the sliding door panel to make any repairs to the components inside the door:

The first part of this video discusses what can happen with the bearings involved in the sliding door operation:

I’ve attached a couple of diagrams (below) to help you see some of the points where the door may be binding and a photo that shows what a corroded pivot may look like.

Please let us know what you find, and if there's anything else we can help with.

Thanks, Wendy W
