My dryer won't start it's not the switch changed that a month ago love the video that helped me and it saved me money took the vent fuse off but don't know how to check and see if it's bad don't have a meter thing.
Just as a test you could connect the 2 leads from the thermal fuse together to see if the dryer will start. If it will then you will need to replace the thermal fuse but do not use the unit until the part is replaced as it is a safety device. If the thermal fuse does turn out to be bad then you will want to check to make sure that the vent is clear from the blower wheel all the way to the outside of your home.
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.
