I got the replacement channel balance from your company and they were an exact part for replacement. I followed the You tube instruction and removed and installed both sides effortlessly. After opening the window the left channel became unhooked from the window sash. Now I can't seem to remove the window to correct the problem. Do you have any suggestions or possibly another Yow tube video on how to get the window out with a disconnected channel balance? The window still opens and closes but it is grinding inside the channel. Any help would be appreciated.
Hmm... there could be a couple different problems. First, I would check the top sash guide to make sure that isn't broken. The top sash guide in your case will probably be a nylon retainer installed on the two upper corners of your sash. They hold the balance in place so it doesn't shoot up in the window. If they are broken or damaged in some way, it may account for this issue. I would also make sure your take out clip is functioning properly.
