Andersen Series 400 sliding door sticking

I have several of the Andersen Series 400 large wood frame sliding doors in a house we just purchased (~50 years old). These are the original doors to the house. I have one door (~92 inches wide) that sticks opening only about 12 inches. I have cleaned the tracks and rollers, adjusted the door for maximum movement but it still sticks. I can see it and I can hear it binding on the frame. I measured the opening and the opening has shrunk. Looking at it from left to right it losses at least 1/4 inch all the way across. I attribute this to the wall settling over time or being squeezed by a new deck put in outside. The door has a clear lite above it so I do not want to break that.

So how do I get this door to slide? Do I take the door off and shave it down? or try to open the opening.?

My spidey sense tells me the former but am looking for advice on how to solve this. Eventually the handle will break as it takes 40-60 lbs to open the door past 12 inches.

 

If I recall, those doors have an interior stop on top that is put on with screws. Take the stop off and look at the gap on top between the sliding door panel and the frame. If it's tight, see if you can lower the rollers a click or two. You still want the door to be parallel to the jamb so also check the latch side when it is open 1/4" to ensure that it's still plumb. Adjust if needed on the rollers.

That's the first thing to check. 2nd thing would likely involve removing interior trim to remove any shims above the door that might be pushing the jamb down too far. You'd cut those shims out and straighten the frame by adding a screw here or there, checking with a long level to ensure it is not bowed.

 

Thanks Sleeper....I did remove the stop to measure. I tried lowering but I can only get one click on the right one and 2 on the left one. My other doors in house have 4 clicks in them so I think my rollers are bad. I will start there before major disassembly. I am assuming remove the stop, drop the door out, replace the rollers and reassemble?
The door is plumb on the outside and at the jamb so its the door that is causing the problems. Stay tuned..

 

I have similar doors at my vacation home built in 1981. After a while they started sticking but not due to settlement. It seems that the vinyl and the weather stripping start to bond. (The doors are closed and not used for 7 months during the winter.) Opening the door about 12 inches before it sticks sounds like a similar situation to yours. Cleaning all the mating surfaces and tracks and using silicone spray on the moving parts and bearing surfaces (tracks) usually relieves the problem.

 

You would only lower them if it is hitting on top. If it's dragging on bottom you need to raise them.

Yes. But as 2john02458 mentioned, it could be friction somewhere else... a hard weatherstripping or tight with dirt.

 

Thanks to all who replied...I did a full WD40 wash on top and bottom after cleaning and all other door sets like this one move much better so I'm still thinking it is a settling thing. I'm going to try new rollers....will keep you all posted.

 

As 2John02458 mentioned, silicone spray is a better choice on vinyl parts. No oily residue to collect dust.
