Defrost Thermistor Sensor Assembly
This sensor monitors the evaporator temperature to determine when the defrost heater should engage. If the thermistor's resistance drifts out of spec, the control board will never trigger the defrost cycle, allowing frost to accumulate until the evaporator is completely choked by ice, blocking airflow to the refrigerator cabin.

Evaporator Fan Motor
The fan is responsible for forced convection across the evaporator fins. If the motor fails or the bearings seize, moisture in the air will settle and freeze on the fins immediately rather than being circulated, leading to a localized 'freeze up' that eventually blocks all air channels to the fresh food section.

Main Power Control Board
The Main PCB contains the logic and relays for the defrost timing circuit. If the relay for the defrost heater fails or the firmware hangs in a cooling-only state, the system will continue to run the compressor without ever entering the mandatory melting phase, resulting in a total ice block of the internal cooling components.
