Things You'll Need
8-inch #2 Phillips screwdriver
Overtime, Pella sliding doors fall out of adjustment. This causes the door to bind when moved or fall off the track, or may cause the lock to stop working. Installed in each Pella sliding door is a mechanism that moves the location of the lower track guide. Making the adjustments correctly will realign the door to reduce these problems. Adjusting the door incorrectly could cause the lower guide to break, or worse, cause the door to jump the lower track.
Open the Pella sliding door.
