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 unit’s 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 unit’s you need to remove the bottom of the sliding unit’s 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.
