Opening your patio sliding glass door should be an easy task. If your
sliding door is giving you a work out every time you open it, most
likely it is your rollers that are causing the problem. The rollers are
located on the bottom of the sliding door and give the door the ability
to slide. Often times they get dirty and wear out, making it difficult
to open the door. If you have an older sliding glass door your rollers
may have become rusty because sliding door units did not always use
stainless steel rollers.
Hiring a professional to replace your rollers could cost you around
$100 not including the cost of the replacement parts. Below are
detailed steps containing all the information you will need to know to
replace your patio sliding glass door rollers yourself.
* Before you start, understand that you need to take the sliding glass
door out of its frame to work on the rollers. The sliding glass door is
heavy. You may need the assistance of another to help you remove the
door.
1) Your patio glass door will have two separate glass units. One unit
is the door that you slide and the other unit is stationary. First,
stand outside your house and look at your sliding glass door. If the
stationary unit is between you and the sliding unit you will most
likely have to remove the stationary unit so that you can get to the
glass sliding unit.
Before you go through the trouble of removing the stationary unit,
first try to go inside your house and see if you can remove the sliding
unit. Usually you cannot because there is a lip along the bottom of the
patio glass door frame (it keeps moisture out of the house) that
prevents the sliding glass door from being removed from the inside.
If the rollers on the bottom of the door are difficult to get over the
lip, you can adjust them to help you create more room (go down to step
2). If it is not the rollers but the sliding unit�s frame preventing
you from pulling the sliding unit out of the door frame, you are going
to need to remove the stationary unit first before you can remove the
sliding unit.
To remove the stationary unit, you first need to take out your screen
door (if you have one). Lift one end of the screen door frame and use a
screwdriver to lift the roller on the bottom of the screen door frame
off of the track. Do this to both ends of the screen door and your
screen door will pull out of the door frame.
The stationary unit is held in place by a metal piece that runs along
the bottom of the track from the corner of the stationary unit to the
bottom of the side jamb (there is a chance this piece is missing but if
you do have one remove it from the track). After you have removed the
metal piece, look for screws holding the stationary unit frame in
place. After removing all of the screws try pulling the stationary unit
out of the door frame. If you are having trouble pulling out the
stationary unit, try placing a screwdriver between the stationary
unit�s bottom frame and the track it is resting on. Lift up on the
screwdriver while you have a helper pull out the stationary unit from
the door frame. Be careful not to use too much force with the
screwdriver so that you do not damage the door track.
2) You may need to create more room when you attempt to remove the
sliding unit from the door frame. To create more room you can adjust
the rollers on the bottom of the sliding unit. By turning the adjusting
screws on the rollers clockwise the wheels move up into the sliding
unit�s frame giving you more room. The adjusting screws are located
either at the bottom of the sliding unit�s frame or in the sides of
the frame. There is a chance that there are plugs covering the screws.
After you adjust both rollers (one on each side of the sliding units
frame) try to remove the sliding unit from the door frame. If the unit
is still getting stuck you may need to get someone to help you. Have
your helper lift one side of the unit and pull outwards while you try
to pry the other side of the unit over the track.
3) To remove the rollers from most sliding units you need to remove the
bottom of the sliding units frame. Most likely the screw that holds the
roller in place is the same screw that holds the frame together. Remove
the screw from both sides of the unit. Then try to remove the bottom
piece of the frame off of the sliding unit; you may need to use a
rubber mallet or a piece of wood and tap on the bottom of the frame
until it comes off of the sliding unit.
Now that you have removed the bottom of the frame you can take a close
look at your patio glass door rollers. Remove one of the rollers and
match it up with one of the rollers on this page

It is a good idea to replace both sliding door rollers at the same time
to prevent extra wear-and-tear to one new roller, which will have to
work twice as hard when paired with an older roller.
4) After your new rollers come in, replace your old rollers with the
new ones. To make it easier to install the sliding unit back into the
door frame, adjust the rollers to be all the way up into the frame.
Once you have the sliding unit back in the door frame you can adjust
the rollers for optimal performance. Keep adjusting the rollers until
the door is sliding back and forth easily
