I recently purchased a fan belt for my dryer and, unfortunately, no instructions came with it to show how to put it back on.

The guy who took it off thought he would be able to put it back on but it is long and sags, when we know it should not. Not sure why instructions don't come with these items.

Is there a way to get some help with this. And, I was wonder if a technician had to come out and put the belt back on, approximately how much would it cost?

Thanks
