Then Monday morning when I turned it on, the fast speed would not work. W: Are you quite sure it worked when you bought it? M: Yes, quite. W: Did someone drop the dryer or knock it off the table? M: No, no one damaged it in any way. It still works fine on low speed. W: Let me take a look. You are right. It doesn't look as though it has been damaged, but it is not working properly.
