Okay let's see if I can make sense of this problem. Here are two pics of the setting knob:
In the first one it is off. In that setting you can only turn it counter clockwise to Cold, then normal, then colder. I thought that cold is the lowest, then normal is a little colder, then colder being the coldest setting.
In the next one it is on cold obviously. When I try to turn it back towards off just the tiniest bit it goes off. And when it's off you can't turn it clockwise to colder, you have to go counter clockwise past cold and normal to get to it.
