See attached images, please. Is this thing the blower resistor? It was in the top of the old AC box which I changed out for a smooth fiberglass non-AC box. Looks like one coil has broken. Can I cut a hole in the top of the new box and drop (a replacement for) this thing in, or does it need to be in a specific place/orientation, or can I omit it altogether since I'm not installing the AC system?
