Maytag DE512 thermal fuse question

Dryer stopped heating. Found a break in the heating element so I’m replacing that. Wanted to make sure that was the only issue so I started checking the thermal fuses, but when I got to the 2 on the blower assembly they have 3 leads.

Anyone familiar with these? I’m guessing the 2 opposite leads are the ones I want, but what’s the 3rd one for?
