Defrost Thermistor (Sensor)
The thermistor monitors the evaporator temperature to signal the control board when a defrost cycle is required. If this sensor drifts out of calibration, the system fails to energize the defrost heater, allowing frost to accumulate into a solid ice block. This ice block insulates the coils and prevents heat transfer, eventually stopping all cooling to the refrigerator.

Evaporator Fan Motor
This motor is responsible for circulating air over the evaporator coils and into the refrigerator cabin. If the motor fails due to moisture in the windings or ice interference, cold air remains trapped in the evaporator housing. This causes the coils to 'freeze up' into a solid mass while the main compartments remain warm due to the lack of forced convection.

Defrost Heater Assembly
The heater is the mechanical component that provides thermal energy to melt frost during the defrost cycle. If the heating element is open-circuit or the thermal fuse is blown, no melting occurs during the defrost interval. The resulting ice buildup physically obstructs the air channels, leading to the reported 'not cooling' symptom.
