I am trying to connect the wiring from the old R/F large element burner switch to the replacement switch (PART 318293825) I received from your company. The old switch has a blue wire connected right next to the black wire. I am trying to under stand what to do with the blue wire on the new switch. The blue wire appears to be connected to each relay on the other elements. Can someone please advise. Please see attachment for photo of old switch with wires attached. The replacement switch has contacts marked 1-H1, 2P, 3-L1, 4-H2 and 5-L2. Your assistance would be greatly appreciated.
