window will not stay up. does taking out the spiril balance release the tenison. could the tenison have been lost causing the window not to stay up?

If I replace the spiril balance 3/8" series 900 23" on both sides of my window do I need the charging tool to recharge the balances? Or do the new balances come charged so I can just replace the old ones that are not working?

Thanks for posting on our discussion boards. Yes, it sounds like the tension of your balances has been lost. I think it'd be wise to try charging them before you buy completely new balances. Please see our 75-006 charging tool for tilt windows.

If you do want to get new balances, you will have to charge your new balances as you install them; our balances do not come pre-charged.

Make sure to see our guide on how to adjust a tilt window spiral balance.
