Defrost Bi-Metal Thermostat
This component acts as a thermal switch for the defrost heater. If the internal contact fails in the open position, the defrost heater will never energize, causing the evaporator coils to become choked with frost. This ice block prevents the evaporator fan from pushing chilled air through the air tower into the refrigerator compartment.

Evaporator Fan Motor
The evaporator fan is the primary mover of thermal energy in this system. If the motor bearings seize or the windings fail, air remains stagnant in the freezer. Because the refrigerator relies exclusively on this forced convection to receive cooling, it will warm up while the freezer stays cold due to its direct contact with the evaporator plenum.

Defrost Timer
This mechanical timer governs the duration and frequency of the defrost cycle. If the internal cam or motor fails, the system may get stuck in the cooling mode indefinitely. Without a defrost interval, the moisture from the air constantly accumulates as ice on the evaporator, eventually sealing the air passages to the refrigerator section.
