Whirlpool Refrigerator Not Cooling: Causes and Fixes

Quick Answer

Whirlpool refrigerators use an adaptive defrost system that defrosts based on usage patterns, not a fixed timer. When the adaptive defrost board fails, the fridge can either defrost too often (runs warm) or not enough (frost buildup blocks airflow). The defrost board is behind the temperature control panel inside the fridge.

The defrost board is behind the temperature control panel inside the fridge. Also check the condenser fan under the fridge - Whirlpool condensers are on the bottom and require the fan to pull air across them.
