Product review (5 stars): Worked perfectly!!!
I have a Samsung Gas Dryer.  Like many others, the display would come on, I would start a drying cycle, and the timer would begin.  However, the dryer would not spin, heat, or anything.  I figured there must be a safety switch between the control board and the actual dryer parts.  Sure enough, this switch was "open" (no continuity) and prevented the dryer from operating.  I disassembled the dryer, replaced this switch, reassembled, and the dryer works like new.
