Margery S Plainfield , IL January 11, 2016 A knob on my dryer wasn't working I switched out knobs with a function that I rarely used and just ignored the problem for a couple of months. Then I looked up the repair and saw how minor it was. Ordered the part. It came in a couple of days. Made the repair in less than a minute.
