Defrost Thermistor
This sensor monitors the evaporator temperature to signal the control board when to terminate the defrost cycle. If the internal thermistor resistance drifts, the board may 'believe' the coils are already clear of frost, prematurely ending or never starting the defrost heater sequence. This leads to progressive ice accumulation that eventually blocks all airflow to the refrigerator cabin.

Evaporator Fan Motor
The fan motor is responsible for forced convection, pulling warm air over the evaporator coils. If the motor's bearings seize or the windings fail, the lack of airflow causes the moisture in the stagnant air to rapidly freeze onto the coils. This creates a localized 'ice ball' that prevents the refrigerator from reaching setpoint temperatures despite the compressor running.

Defrost Heater Assembly
The defrost heater is a resistive element that provides the thermal energy necessary to melt frost during the defrost cycle. If the element reaches an open-circuit state due to thermal fatigue or moisture ingress, the frost accumulated during normal operation is never cleared. Over 24-48 hours, this frost turns into solid ice, completely insulating the evaporator and stopping all cooling capacity.
