For Whirlpool Microwave Door Interlock Switch (Part Number: OEM13289661)

Chris for Model Number WMH73521CB-0

Hi, I really need your help with my whirlpool microwave. I ordered door switches and decided to replace all three. Now the display says close the door before operating. If I open the door is turn on the microwave in normal operation. There are three switches in this microwave. One is a three prong and the other two are dual prong. Do you know the sequence of how the wires are suppose to be wired up? The three prong switch I have a picture of but its with the others. Please Help! I really appreciate your help and support. Chris

Hello Chris. You have it wired wrong. On the 3 wire primary, there is a COM and it should be black. NC should be Orange, and NO should be a white and black wire.
