Track Sliding Patio Door Rollers

Question

I think I'm going to have to replace the rollers on a really heavy sliding glass patio door. I know I have to get the door off to see what kind of rollers it has, but I'm hoping you can help me do this. I know I have to lower the rollers (or door) all the way so I can lift the door out of the track, but I'm not sure which screw does this. On both ends of the doors there's a screw and above the screw there's a hole with another screw inside. Can you tell me what each of the screws adjust/control?
Thank you

Hello there. The adjustment screw is normally located at the bottom; however, I believe in your case it's the top. The hole with the other screw inside should be the adjustment screw, since that screw sounds like it fastens directly to the roller housing, rather than the door frame. Note too that you actually want to adjust the rollers to the highest point to remove the sliding door, not the lowest. See the video below for further details, and let me know if you have any other questions.
