Left burner of does not work

My left burner (main dual burner) does not work and technician said need change switch. It is Kitchen Aid model KECC502GBL3. I ordered part number AP3672660 and it is very different than the one original in there. Connected the wires as instructed then burner can not be turned on, and after switching the wire, it turns on the main burner but touches the break whenever turns on other burners. Is that the right part number?:eek:
