Evaporator Fan Motor
The evaporator fan is the primary mechanism for moving chilled air from the cooling coils into the food compartments. The 'loud' symptom indicates the motor bearings have failed or the impeller is striking ice, while the 'warm' symptom confirms the resulting loss of airflow. Replacing the motor restores the necessary CFM (cubic feet per minute) of air across the evaporator to maintain set-point temperatures.

Defrost Sensor (NTC)
If the noise is caused by the fan hitting ice, the root cause is often a failed NTC thermistor that is misreporting evaporator temperatures to the control board. This prevents the defrost heater from activating, leading to frost blooming that physically obstructs the fan. Replacing this sensor ensures the defrost timing logic receives accurate data to keep the fan shroud clear.

Main Power Control Board
The control board manages the voltage pulses sent to the DC fan motor. If the board's fan drive circuit fails or provides erratic voltage, the motor may produce high-pitched electronic noise or fail to spin at the required RPM to cool the unit. This is considered if a known-good fan motor fails to resolve the temperature drift.
