Ages ago, I fitted a Screwfix window in the kitchen. Stock size UPVC DG.
Approx 2x1m, three panels, outer two being casement types.

One - the least used one - has jammed shut. But does release the middle
and bottom catch. Tapping the top with a rubber mallet got it open.

The bottom latch moves up and down with the handle. The top one only
upwards, but with the handle in the open position can be pushed down.

Be a shame to have to buy a complete new window, as other than this it is
fine.

Not sure how you get at the mechanism - looks like the DG panel may have
to come out?

If I could get at it, would spares be available - or could it be repaired?

Any tips gratefully received. Not done anything like this before.

All the ones I have seen have mechanisms like these:

that are accessible once the window is open. Does yours run in an
internal guide? If you remove the handle and the screws will it simply
fall out?

Normally the mechanism in the handle part breaks but yours sounds a
different problem.
