UPVC Doors Won't Lock In Sunshine

Tinkerer · 2013-05-02T15:52:59+00:00

We have a pair of UPVC doors on our porch. One is only opened when required for large items to be taken into the house and it carries the frame into which the "everyday" door locks. We have found that the locking mechanism for the "everyday" door works fine until the sunshine arrives. In the afternoon sun it presumably gets very hot and the handle will only lift just over half the normal distance which is not sufficient to allow the key to be turned although I do not think the problem is the handle as it operates fine when the door is open. Once the sun is off it the locks work fine again but that is no use if you need to lock up during the afternoon. I can't imagine that we are the only people to have experienced this problem. I assume that the door is expanding/bending in the heat and some adjustment is required. Problem is that I cannot identify which part of the umpteen part locking system is jamming. I was wondering if anyone else had experienced the same problem, or is familiar with this type of door, and could suggest how to find where it lies.

2013 eh, I'd imagine they got so pissed off they got a new door by now. Its a problem though as I had to take my bottom lock off to make the door handle go up enough, but still cannot see where its binding. Brian

Fair point about the op date Brian but isn't it nice to discuss a physical problem instead of the torrent of political bullshit?
