My oven Kenmore Elite 790.42763512. Both bake and broil stopped working at the same time. Control panel seems to operate fine, but coild don\'t heat. I removed and tested the safety cutoff thermostat and it was bad (tested open).Question: can i temporarily short the terminals of the thermostat to find out if that is the issue? Or will the oven not work if a new thermostat is not present?
