How To: Sliding Glass Door Rollers

Step 1. Remove sliding screen door by prying wheels off track with a flathead screwdriver. Back off adjusting screw if necessary.
Step 2. Remove screen and set aside after close inspection for any needed repairs.

NOTE: It is recommended that some protection be provided for carpeting and floors during this procedure.
Step 3. Check upper track and remove any anti-lift devices. In most cases, the sliding door can now be removed. With the help of another person, lift the door up into the top track, tilting the bottom of the door out of the lower track. Lower the door to clear the top track and walk the door to the work area.

NOTE: Some doors cannot be removed unless other steps are completed. If your door has been removed at this point, please move on to Step 6.

If your door cannot be removed please continue on to Step 4
Step 4. It won't come out!!!

The rollers may have been adjusted so far that they lock the door on the track. You will need to adjust the rollers back up into the frame using a Phillips screwdriver and turning the adjustment screw counterclockwise. The adjustment screws are located at the very bottom corner of the door, through a small hole or "U"-shaped punch.
WARNING: DO NOT REMOVE EXPOSED SCREWS ON THE DOOR SURFACE, THESE HOLD THE GLASS FRAME TOGETHER! ADJUST ONLY THE SCREWS THROUGH THE HOLE OR SLOT!

The door should start to drop as the screw is backed off. You may need to bounce the door to release accumulated rust and dirt, letting the rollers slip up into the frame.

Step 5. It's still in there! In some cases, the addition of raised hardwood or tile floors prevents removal of the sliding door. This requires removal of the door from the outside. You will need to first remove the fixed glass panel.
Step 5(a). Remove the threshold, if necessary, to move the fixed door within the frame. Simply prying up with a flathead screwdriver should be sufficient to remove the threshold on most doors.
Step 5(b). Some fixed doors may require that you remove retaining screws on the inside of the stationary door. These will be located at the bottom, middle and top of the door.
Step 5(c). Slide the fixed door towards the center of the doorway. (This may require extra effort depending on the age of the door.) With the help of another person, lift the door from the track and set aside. The sliding door can now be removed and positioned on edge to allow access to the rollers.
This would be a great time to clean the bottom track wall jambs. If you purchased a replacement track bead, snap it over the damaged roller track now.


*** Removing Door Rollers ***
Step 6. Determine if the corner frame screw goes through the roller tab. If it does, it is okay to remove the frame screw at this time (a little oil may help.) Some rollers have flared tabs to lock them in place. If necessary, bend these inward to release roller. Some rollers only load in from the side of the bottom rail. The frame screws on both sides must be removed Carefully pull off the bottom rail to expose the end. Remove the old roller ( you may need to pry out the housing if there are locking tabs on the side).

Use extreme caution in removing the bottom rail as older doors do not generally have tempered glass, and excessive force could cause the glass to break. Old dry glazing putty also poses a real problem. Call a local glass professional if your rail will not remove fairly easily.
Step 7. With a slotted screwdriver, pry the roller loose and remove.
Step 8. Install replacement roller and door frame screw if needed. Reverse any steps taken to reinstall the door. It will be necessary to check the door for "square". Adjust the rollers up OR down to align the door with the wall jamb. In addition, the door must be aligned to insure proper latching. Once aligned, reinstall the fixed panel if necessary, and all frame screws in the proper mounting brackets.
