Coil Balance General Question

A home owner from Natick, MA says:

Hello,

I have a coil balance spring system on a window where the lower sash will not stay open.

When observing the coil balance, it's obvious the coil spring has slipped off the coil balance clip. This is on both the left and right sides of the window.

The coil spring is bunched up with the shoe. I am tempted to remove the clip and just remount the spring.

Could you tell me how to see if the balances are broken? Is it possible the coil spring simply slid off the clips?

I am not at the property now, but can upload photos once I return.

Thanks.

Hello again. Obvious now that the coil spring has snapped and is broken on both sides.

Could you recommend which parts I need to replace this?

The coil spring reads a number "8" at one end.

Do different sides of windows generally have different numbers?Thabk you.

Hi there, it looks like you need a new S152-8 coil balance spring. Also look over the complementary parts 15-143, 15-144, and 15-175. Let us know if you need any further explanation.
