This is often due to not having put the spacers in the
right places around the sealed units and plastic panels,
which will prevent this if correctly packed into the
frame.

sorry, in my panic I realised I got the question backwards.

I realise now that what I meant was that in order to lock the door I'm
having to push the lever upwards until I was applying force (presumably
lifting the door) whereas before it simply clicked into the "engaged"
position.

For some time the "roller" catches at the bottom of the door had been
catching on the channels, thus requiring me to nudge the bottom of the
door
to open it.

So the implication is I should be able to tweak the packing to square it
up
?

Check this is the problem first -- measure the two diagonals and
if the door has a tapezoid deformation, they will be different.

You might get enough access to repack just by removing the beading.
If you have to remove the panels/units, you will probably need new
window tape too when you refit them.


thanks - I'll check - rings true since things are catching at the bottom of
the door and not the top.
