Defrost Temperature Sensor (Thermistor)
This sensor monitors the evaporator temperature to signal the end of the defrost cycle. If the sensor drifts out of its resistance range, the main PCB may fail to trigger the defrost heater, allowing frost to accumulate on the evaporator coils until airflow is restricted.

Freezer Door Gasket
A compromised or torn magnetic gasket allows humid ambient air to enter the sub-zero freezer compartment. This moisture undergoes a phase change (desublimation) upon contact with the cold surfaces, resulting in 'snowy' frost buildup throughout the freezer.

Defrost Heater Assembly
The heater is responsible for melting accumulated frost from the evaporator during the timed defrost dwell. A fracture in the heating element prevents thermal transfer, causing the evaporator to bridge with ice, which eventually migrates to the freezer liner as visible frost.
