A common problem with sliding screen doors is wear and tear on the wheels. This brings about unleveled screen door, which causes it not to slide smoothly. Replacing the wheel with new ones can correct the problem and this can be easily done at home.
Step 1 - Remove the Screen Door
Locate screws that support the door and use a screwdriver to loosen them. Get an extra person to hold it still and lift the door from its frame.
Step 2 - Remove Old Wheels
At the bottom of the sliding door, use a screw driver to push up the wheels and slide them in to the frame. This causes the frame to lift up and out. Dismount the lower part of the frame from the sliding door. Locate two screws and use a screw driver to remove them from the frame. Remove the frame from the sliding door and place it in a safe position. Get the wheels off from the frame.
Step 3 - Replace Sliding Door Wheels
Put the new wheels in and fasten them in position. Make sure that they are rolling freely. Attach the lower frame to the sliding door and push the wheels into the frame. Reattach the door using screws and test the condition of the wheels.
