The 46-75615 is a larger-capacity French door model, and at this size the dual-door seal alignment matters more than on a narrower unit — a door that seems to close fine but isn’t sealing evenly on both sides is one of the more common causes of the temperature complaints we see on this model.

Bottom-freezer models like the 46-75645 put the compressor and most of the sealed system underneath the fresh-food compartment, so a warm-running fridge on this configuration is diagnosed starting from the airflow path between the two compartments rather than assuming a compressor failure outright.
