Sliding Door is Stuck, not sure how to repair?

So I came home to one of my live-in tenants telling me the sliding door is stuck, it is really stuck!

If I lift it up on the left side and pull I can bring open it to the left. If I lift it up on the left side and move it to the right I can move it. I cannot move it at all if I don't lift the left side...

Here are some pics with a little background:

I use the 2x4 in the pic to lock the door because of the doggy door. The 2x4 works great and is pretty snug - I've been using it for a year with no problems. I just started requiring the tenant to use the 2x4 also because I got tired of him never locking the door. The 2x4 fits snug, snuggly enough so that if you don't put it in properly, and you try to force it, it MIGHT have been the cause of this problem I'm having?
The door went from working perfectly fine one day to having this issue the next - is that normal or did something probably cause it?

 

Hard telling. Sounds like a roller problem, and might have nothing to do with the tenant at all. If the bearings go out the roller could bind or come off, or even get lodged where it would bind. You will need to remove the sliding panel to find out either way.

On some doors a stop comes off the top inside then the top of the door can tip in on top. Others need to have the rollers lowered so that the door can then be raised up off the track and the bottom tips in first. Still others (with a tall lip on the inside threshold) need to have the exterior panel removed first... (to the outside) and once it's out of the way then the interior panel lifts up and also tips to the outside. Occasionally there is a threshold cap that has to come out to let the fixed panel slide to the center... and there is often a clip on the jamb that holds it too. No way to say exactly what you need to do but first thing I would do is get the door out and check the rollers.

 

Any advice on how to get this door removed? It seems like there is VERY little give to lift the door up (and then out)..

Number one, lower the rollers. Screwdriver inserts from the end. Lowering the rollers increases the ckearance on top by letting the door down. If it doesn't lift up high enough the clear the track once the rollers are down then you probably have to start from outside. (Fixed panel first). Use a couple prybars but be aware you can dent the frame of you aren't careful. 2 guys with suction cups would be better.

 

Along with lowering roller on top, raise them on bottom. The idea being leaving the frame as the limiting factor. Hopefully this give you enough room to lift and swing out the bottom, if that's the type of door you have.

I just replaced the rollers on my screen door and had to lower/raise the rollers. Then due to the track itself slightly warped, I had to pry down the track (vinyl) to allow enough enough room for extraction. Planning on replacing entire door next year due to age/wear.

 

I think you just contradicted what I said. This isn't a screen door. And there are no rollers on top of it.

 

Might have to start from the outside then... The door is presently resting on the track, lowrig the roller wouldn't do anything! I think...?

 

Didn't mean to, just read "lowering" and assumed this door might have had top rollers. Guess my vernacular is incorrect, to me you "raise" the roller into the door on the bottom not lower them. But I'm not in the biz...sorry

I just described my example to illustrate his frame might be slightly warped and what I did to remove a door. But it sounds like he might have a different type of door, more like the others you described.

 

Patio door rollers are adjusted from the end with a screwdriver. As you tighten the adjusting screw, the roller moves downward, which raises the door up... making less clearance on top of the door... making it impossible to raise it high enough to remove.

By lowering the roller adjustment (sucks the roller up into the door) until it won't lower any more, you maximize the amount of clearance above the door.

Raising the roller would mean extending it... it moves the roller downward... which would in turn raise the door, making it tighter on top... the opposite of what you need to do. Turning left lowers the door... turning right raises it.

Also in one of your photos, the door does not appear to be centered on the track. You would need to lift it up an center the door on the track (push it up and out then let it down) for the roller to be centered on the track. That semi-circular cutout should be directly over the monorail.

 

Thanks for your help! XSleeper, I did not know that and haven't tried setting it back on the track, could that be a possible solution? The door doesn't move even a smidge, I would think that it would at least mover some if it was off the track?
