When the dryer is on there is a clicking noise as it turns. It's pretty loud. I found that when you open the door and hold the safety button in, with a lot of pressure, and turn it on, the noise stops. So it must be in the safety button. What do you think? Will you please give me instructions on how to fix it? I do not have a manuel. Also I need to replace the control dials. They are wearing out. Thank you for your attention to this matter.
