Plugged right in where the old timer went.  The Dryer would not automatically shut off, nor would it begin to heat.  The heat part is not always related to the timer however it can be a culprit.  When I disassembled the old timer I noticed a broken metal piece of the switch that was not connecting to close a circuit.  This item is a direct replacement for dryers with timers of the same design/number.  It was a Whirlpool replacement part.
