  • It seems like I cannot find a picture of your component (if you ever posted any). If it is metallic looking, it is probably a thermal cutoff of some sort. The wikipedia article focuses on the fuse-looking one, but there also exists a flat metal plate looking one. The connection is usually normally open so if the temperature on the loop is ever too high, the motor (compressor) will trigger. The normally closed connection one is for motor overheat protection. That kind is usually placed/glued to thbe e stator body, so if it ever gets too hot, it will stop the motor instead.

    Edit: The picture provides a clearer size of the metal plate. A plate of that size is not a thermal cutoff. I don’t know what it is either. But if it is indeed a heater, you should be able to measure the resistance. If it is a resistive heater, usually it will have a low resistance (usually <10R). And metal is not “cold” at room temps, they are the temperature of room temps. It just feels cold because of higher thermal conductivity
