I'm not sure if the diagram for my Coldspot was wrong, or an assembler took a switch off a different model and installed it, but I got a little frustrated that the poor customer service agent kept wanting to scroll through all the diagrams since I told him the door switch wasn't the one in the diagram. It dawned on me later it wasn't him, when I went on an other site and the same diagram was on there was well- the switch had had three equidistant prongs, when this one has two close together and a third one farther away. Needless to say I ordered this one by appearance and not "compatible model" and it worked flawelessly.
