All the research I've done on this part states that you know it is broken if it rattles when you shake it. Apparently there is a ceramic piece inside that breaks when overheated. Well. this new one I received today also rattles when I shake it. I don't know if it is broken too or not. I'm leaving this feedback to memorialize the issue in case I have to return it. I will update this feedback after I install the part.
