My oven went out mid baking. Both elements are out. Preheat light is also out. Stovetop still works fine. Do I just need a thermostat? If so which one? My serial # is 10290417SS.

Sarah for Model Number CER1140AAW

ANSWER Hello Sarah. Test and see if there is power coming to the thermostat. If so, and the thermostat is not sending power to the elements, you will need to replace the thermostat 74009379 in 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
