Defrost NTC Thermistor
This sensor provides temperature feedback to the adaptive defrost control board. In Bosch units, sensor drift causes the control logic to incorrectly determine that the evaporator is clear of ice, leading to incomplete defrost cycles and cumulative frost migration into the freezer cabin.

CONF
Freezer Door Gasket
Any compromise in the magnetic seal allows warm, moisture-laden room air to enter the negative-pressure freezer environment. This moisture undergoes a phase change (desublimation) immediately upon contact with the evaporator or cold liner walls, creating rapid frost buildup that the defrost system cannot keep up with.

Defrost Heater Assembly
The defrost heater is a resistive element designed to melt frost from the evaporator coils during the timed defrost cycle. If the internal filament fails, the evaporator will become completely encased in ice, eventually visible as frost 'snowing' out into the main freezer compartment due to restricted airflow.
