Temperature Sensor (Thermistor)
Temperature sensors in Samsung units are prone to 'drift,' where the resistance values no longer correspond accurately to the actual temperature. This causes the main control board to cycle the compressor and evaporator fans based on false data, leading to the observed thermal instability. Replacing the sensor restores the integrity of the feedback loop required for the PID controller to maintain a steady state.

Ice Maker Assembly
This specific model series often suffers from air infiltration or frost buildup originating in the ice maker compartment. If the ice maker fails to seal or cycle correctly, it creates a localized heat load or 'ice ball' that disrupts airflow from the evaporator. This causes the refrigerator's logic to overcompensate in other zones, resulting in fluctuating temperatures throughout the cabinet.

Main Power Control Board (PCB)
The main PCB manages the complex timing between the dual evaporators and the variable-speed compressor. If the relay logic or the inverter control circuit on the board begins to fail, it can result in intermittent power delivery to cooling components. This lack of consistent actuation prevents the system from reaching a thermal equilibrium, manifesting as erratic temperature swings.
