For non-tilt windows, the first thing you can try is applying silicone spray to the track. We like this more than oil as a lubricant because it doesn't attract debris. If that doesn't work, and if there is a lot of sideways play with the sash, you might want to install a face guide (like our 67-002, for example) to keep it steady.

We don't have an official guide, but I would be happy to explain myself. Put two 67-002 face guides on each side of the sash, about three inches from top and bottom. You want to take the flat wing of the 67-002 and place it between the sash and the window frame. Push into the window frame so that it's just barely touching (so it doesn't jam up when you raise and lower sash) and drill a 7/32" hole. Then, screw the guide into the sash with a #6 x 1/2" flat head screw. Repeat the process with the other three.

It will prevent the sash from slipping further in on one side and jamming.
