Why is my Whirlpool refrigerator not cooling properly while the freezer is still working?

There could be several reasons why your Whirlpool refrigerator is not cooling properly while the freezer is still working. One common issue is a malfunctioning evaporator fan, which circulates cold air from the freezer to the refrigerator. Another possibility is a faulty defrost system, which can lead to ice buildup and block the airflow. It is also possible that the condenser coils are dirty, preventing proper heat exchange. I recommend checking these components or contacting a professional for further diagnosis and repair.
