Defrost Heater Assembly
This component provides the thermal energy required to melt frost from the evaporator coils. In this model series, the heater often develops an open circuit or structural brittleness, preventing the defrost cycle from executing. When the heater fails, ice builds up until airflow is completely restricted, causing the 'not cooling' symptom.

Defrost Sensor
This thermistor monitors the temperature of the evaporator and signals the control board to terminate the defrost cycle. If the sensor fails or provides an incorrect resistance value, the board may never initiate the heater or may terminate the cycle prematurely. This allows residual frost to turn into solid ice over several cycles.

Evaporator Fan Motor
While often a secondary failure, the fan motor frequently fails when ice accumulation from the defrost fault physically obstructs the blades. The mechanical resistance causes the motor windings to overheat or the plastic blades to fracture, resulting in a total loss of forced-air convection even if the compressor is running.
