John L. for Model Number 100.68632700 On the push to start button on my dryer, does there need to be 120 volts on all four prongs?
Answer Hello John, If there were 120Vac on all prongs, there would be no use for the switch since a switches job is to discontinue or pass the voltage. You will need to refer to the wiring diagram to discern the wiring and determine which should have voltage and which is the load side of the switch. We can assist you further if you could please re-post with the verified model number from the units' I.D. tag. Read More... Answered by AppliancePartsPros.com | Friday, April 25, 2014
