Evaporator Fan Motor
The evaporator fan motor is responsible for circulating air over the cooling coils and into the cabinet. The 'loud' noise indicates the fan blades are either hitting ice buildup or the internal motor bearings have seized due to moisture. If the motor fails to reach its target RPM, the heat exchange process is halted, causing the interior temperatures to rise.

Defrost Controller / Thermistor
A failure in the defrost thermistor prevents the refrigerator from correctly identifying when to melt frost off the evaporator coils. This leads to excessive ice buildup that physically obstructs the fan blades, creating a loud grinding noise and blocking airflow, which results in the warm cabinet temperatures.

Main Power Control Board
The main PCB manages the defrost cycles and the pulse-width modulation (PWM) signal to the fan motors. If the board's logic for the defrost circuit fails, it allows for the ice accumulation that creates the noise and cooling issues reported. This is the root cause if the fan and sensors are found to be electrically functional.
