Well, put me in with the group who've had the stem snap on the temperature sensor. I was trying to move the wire over to avoid heat sources, so I went to loosen the nut, and it came off with the threaded stud.
I had read how fragile these things were so I thought I had made sure not to overtighten, but it's kind of ridiculous how brittle they are. Speedhut really needs to revisit the design.
Sorry, just frustrated, and had to vent a little. Three steps forward, two steps back.
