Thanks for posting! A broken tilt shoe can cause top sash to fall, but if shoe is intact then you might have to simply charge the spiral balance. For tools on how to charge, please see our 75-006. If that doesn't work, then you may need to replace your hardware.
Looks like you might have our Series 600 spiral balance. Furthermore, the broken tilt shoe looks like our 15-046. Do you think these may work for you? Take a look at them and compare them to your own hardware. You may also want to check out our video on tilt windows, which shows how to replace a spiral balance, as well as how to charge one: |
