I have a 20 y/o aluminum patio sliding door that has become stuck at the beginning. Once, you push the sliding door past a certain point (~9 inches away from the starting point), it is all smooth, buttery operation.Because of that, it's making me think that the wheels aren't the problem here. If the wheels were the problem, then the sliding door would be rough/sticky for the entire operation.I have tried to clean/lubricate the wheels, track, and play around with the adjusting screws that lift the wheel higher. I've also detached the glass panel from the frame and tried rolling it on the track...still get the same results. Are there any other options?Thanks! via /r/DIY https://ift.tt/2LR2Ozz
