I have a double-glazed exterior door from my kitchen, but it won't open. the lock seems fine, locks and unlocks okay, and I can see all 3 lock thingies are retracting properly. it opens about 1cm, then seems to hit something. I've studied the edges and can't see anything blocking it, so I assume it's shifted on its hinges a bit? maybe??
it's been making a bit of a screeching noise for a long time (only on opening and closing!), from the bottom edge.. I think it's been scraping against its frame.
Does it get direct sunlight? If so, it may have expanded in the heat. Underneath each of the hinges there's a place for an allan key. A few turns, on each hinge, should lift it enough to clear the sill
Sara, my leetle affadavit.............. there aren't any hinges, just rollers probably. The screeching was the door rubbing on the track. Sounds like it's sort of sunk on its wheels.
Somehow.......... you'll have to lift the door at both ends and slide it open. Then, I can probably tell you where the adjusters are ........... er ......... hopefully ;o)
It lifts "within" the frame Ra. Someone each end levering it up and dragging it along.
Not easy. I'm loathe to suggest you go out in the street and wrestle a couple of passing rugby players in to help you. I'm a great supporter of "girl power" ;o)
ooo-er .............. have I got this wrong? I was assuming it was a sliding patio door. OOps.......... just a regular hinged door then that won't open?
Ok Sara ........... uPVC door. It's just dropped on the hinges I guess. Nothing's standard, but they usually have a hole in the hinge to put a small Allen Key. Probably have to take the hinge covers off (one screw maybe?)
Have a look at the hinges.
