Defrost Bi-Metal Thermostat
This temperature-sensitive switch manages the power supply to the defrost heater. If the internal contacts fail to close when the evaporator reaches sub-zero temperatures, the defrost cycle will never initiate, leading to excessive frost accumulation that physically blocks airflow to the refrigerator section. This specific part is a high-frequency failure point due to seal degradation.

Evaporator Defrost Heater
The heater is responsible for the thermal phase-change of accumulated frost into water during the defrost cycle. If the resistive element within the heater burns out, creating an open circuit, the evaporator cannot shed frost. This results in the same 'frozen' state that prevents the convective cooling of the upper cabinet.

Main Control Board
The control board acts as the defrost timer and logic controller for the appliance. A failure in the specific relay or logic gate that manages the defrost sequence will prevent the system from ever leaving the cooling mode. This component is recommended only if the thermostat and heater have been verified to be functional.
