Hello, hoping to get some help in replacing a part on my dishwasher. The energy selection/cycle switch is broken on my current model. I had ordered the correct part form here and went to replace the older one.

After getting things apart and to the switch I noticed that there are three metal prongs with leads coming off the back of the old switch, but only two metal prongs, and a couple plastic prongs on the back of the replacement part ( WD21X732). As I understand it, this is the correct replacement part from GE. I am unsure as to how to hook up the replacement part at this point.

Edit to add a question. Could this switch being bad also result in the heated drying not working?
Any help would be appreciated,


Thank you
