Things You'll Need

Clean the lower track with a rag to remove dirt and grime that can cause the door to jam.
Adjusting the rollers on your Pella sliding door may be necessary to keep the door operating smoothly. The sliding panel should glide across the tracks when you open the door, without jamming. Over time the framing of your home settles. As the framing inside the door opening settles, the tracks raise or lower with the floor. Adjusting the rollers on your Pella sliding doors raises or lowers the door panel, as necessary, to get the door working smoothly. When adjusting the rollers, you will need to adjust each side of the panel.
Open your Pella sliding door halfway. Find the small plastic cap on each edge of the sliding door panel near the bottom.

Pry the caps away with a putty knife to access the roller adjustment screw for each roller. Turn the screw clockwise with a Phillips head screwdriver to lift the door panel off of the lower track if the door is rubbing against the lower track. Turn the screw counterclockwise to lower the panel if the door is rubbing against the top track.
Adjust the roller on the opposite side in the same manner. Open and close your Pella door to test the panel's operation. Continue making adjustments as necessary. Push the caps back into the adjustment holes once you finish.
