Defrost Heater Assembly
This resistive heating element is responsible for the radiant melting of frost during the defrost cycle. If the heating filament fails due to thermal fatigue, frost will accumulate into solid ice, creating a thermal barrier on the evaporator coils. This prevents the heat exchange process, leading to the cabin temperature rising while the coils themselves remain frozen.

Defrost Bi-Metal Thermostat
This temperature-sensitive switch completes the circuit for the defrost heater when the evaporator reaches a specific sub-freezing threshold. If the internal contacts fail to close, the defrost heater will never receive power regardless of the control board's command. This results in perpetual frost buildup and a subsequent loss of cooling capacity.

Evaporator Fan Motor
The evaporator fan is responsible for forced convection, moving air across the cold coils and throughout the refrigerator. If the motor fails mechanically or electrically, air remains stagnant, causing rapid frost accumulation from humidity and preventing the transfer of cold air to the refrigerator compartment.
