Small correction, no motor runs backward. You can't reverse the flow through a compressor, so heat pumps have a reversing valve that slides back and forth to reverse the flow of refrigerant in the system.

Here's a fun video to watch

Oh fair point. My dumb-ass sitting here going what is he talking about? A motor can run backwards, most pumps and compressors can't, or at least wont be effective if they do. Unless their something like a peristaltic.

Lol yeah, a motor can run in either direction, but I can't think of any that do in the equipment I service as part of normal operation right now.
