Freezer Door Gasket
The magnetic gasket creates a hermetic seal to prevent latent heat and moisture from entering the sub-zero environment. If the vinyl is warped, torn, or has lost its magnetism, humid room air enters the cabinet and undergoes a phase change, depositing as frost on cold surfaces. This is the most common cause of 'snowy' frost near the door or shelves.

Defrost Thermistor
This sensor monitors the temperature of the evaporator coils to signal the control board when to terminate the defrost heater. If the thermistor's resistance drifts or fails, the defrost cycle may terminate prematurely or fail to initiate entirely. This leads to a gradual accumulation of frost that eventually migrates from the internal coils into the freezer compartment.

Defrost Heater Assembly
The defrost heater is a resistive element responsible for converting electrical energy into thermal energy to melt frost off the evaporator fins. If the internal filament reaches an open-circuit state, the unit cannot remove the ice that naturally forms during the cooling cycle. Over several days, this frost will build up and become visible to the user as airflow is restricted.
