Kenmore Refrigerator Not Getting Cold?

I have a Kenmore refrigerator with bottom freezer, model #59666032600. The freezer works, compressor works, and the compressor fan works, but the refrigerator does not get cold.

The air regulator gate in the refrigerator opens and closes okay.
Is there another fan that sucks air out of the fridge compartment that might have failed?
