Remove the two wires going to the switch and place a jumper made of a piece of Romex shapped like a U with a 1/4" of insulation removed from each end.wire between the two fasteners. Make certain you do this with the power off and the stove unplugged (yes folks I know that the vac switch may not have line voltage on it but trying to keep every setup in the noggin is taxing). Make certain that the patched cord is not touching any thing metal plug the stove in and hit run.
