Answer Hello Kenneth. Based on the information you provided, you will need to look for a wiring issue with the unit. If all the parts are new, there has to be a wiring issue with the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
