It could be caused by an ailing or damaged sash chain or a sashweight that is not aligned properly or not attached to a the sashweight, or even a broken or damaged pulley.
The sashweights are small, rounded boxes made of cast iron that support the counter-weight system as well as support the sash. They are located at the bottom of every window frame.

The problem can be caused by a variety of things, including excessive force, aging, the lack of maintenance or accumulation of moisture. It's important that you replace the old cords during window sash repairs with new ones made from materials that are strong and resistant to moisture.

After removing the stops, you can get access to the weights on the sash by opening the jamb or removing the weight pocket.

First, you must remove the old cords by cutting them close to their knots, and then pulling them away. Then, take the sash from the frame and put it aside. After the sash has been removed then pull it back down on the staff bead (the nail that prevents the sash from falling) and insert the nail, which is about one foot long into the hole for the staff bead. This will stop the sash from slipping away while you finish stringing the counterweights.
After installing the upper sash again then reattach the sash cords and make sure the sashes are in a balanced position and move smoothly. Install the lower sash and repeat the process. Verify that the sashes are properly placed and are moving smoothly.
Once you've completed installing the counterweights, reattach the sash cords by putting a sash cord through the pulleys and threading the other end of the cord through a knot hole inside the sash to secure it in the correct position. Repeat the procedure for each side of the sash until cords have been replaced and the sashes are operating normally.
