hi... whilst lifting the door handle on my conservatory door to lock it I felt something " go " and now the door will not open. the handle is slack and does nothing, the door will lock and unlock with the key. i'm guessing the roller bar has broken. I cannot get to the grub screws on the hinges because the doors are closed, so I am stuck with a door that will not open. any ideas please.
