It could be caused by a damaged or missing sash chain or a sashweight that is not aligned properly or not attached to a weight, or a damaged or cracked pulley.

The sash weights are small boxes, typically constructed of cast iron that help support the sash and also support the counter-weight system in the window.

Repeat the procedure for each side of the sash until all the cords are replaced and the sashes are operating normally.
