How to Replace and Adjust Rollers on an Andersen Gliding Patio Door

1. Gather Tools and Materials

   • Find the installation guide that came with the rollers.
   • Screwdriver or drill with Phillips bit.
   • Large and medium to small flat blade screwdrivers.
   • Work area that can support the door without scratching it.
   • Someone to assist you.
   • New rollers available from an Andersen dealer or at parts.andersonwindows.com.

2. Safety Precautions

   • Do not attempt to lift and move the door panel alone.
   • Lock the door securely to prevent it from tipping forward.
   • Have someone available to assist you throughout the process.

3. Removing the Door Panel

   • Use a Phillips screwdriver to remove the head stop while someone braces the door.
   • Unlock the door and have someone strong on each side to tilt the door panel forward and out.
   • Carry the door to your work area.

4. Replacing the Rollers

   • Identify if your door has old-style or newer-style rollers.
   • For newer-style rollers held in place by compression, use a medium flat blade screwdriver to release the barbs holding them against the wood inside the door.
   • Remove the old rollers and dispose of them properly.
   • Snap the new rollers into place, ensuring the adjustment screw side faces the right direction.

5. Reinstalling the Door Panel

   • Carefully carry the door panel back to the doorway with assistance.
   • Tilt the panel back into place, ensuring the rollers are positioned properly on the rail of the track.
   • Lock the door securely and replace the inside head stop with the same screws.

6. Adjusting the Rollers

   • Open the door approximately half an inch to assess the reveal or gap between the door frame and the door panel.
   • Adjust the rollers accordingly:
     • If the gap is wider at the bottom, raise the roller closest to the outside frame or lower the one closest to the center.
     • If the gap is wider at the top, do the reverse.
   • Make adjustments until the reveal is even and the door panel moves smoothly in the frame.

7. Final Steps

   • Once adjustments are made and the door is aligned, close and lock the door securely.
   • Test the door to ensure it moves smoothly and stays aligned.
