How do you tell if a switch is bad?
Answer Hello Joe. You can use a meter and test for power coming into the switch 74007840, and when the switch is turned on, you will test for power coming out and going to the element. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
