Freezer Door Gasket
The gasket provides the critical thermal barrier between ambient kitchen air and the freezer cabin. If the magnetic seal is compromised or the vinyl is deformed, humid air enters continuously, reaching its dew point and desublimating into frost on the freezer walls and food. Replacing the gasket restores the airtight seal and prevents external moisture migration.

Defrost Thermistor
This sensor monitors the temperature of the evaporator coils to signal the control board to terminate the defrost cycle. If the thermistor shifts in resistance, the system may fail to initiate or complete the defrost sequence, allowing frost to bridge the evaporator fins and eventually fill the freezer compartment. A new thermistor ensures the control board receives accurate thermal data for cycle timing.

Defrost Heater Assembly
The heater is a resistive element that provides the thermal energy necessary to melt frost from the evaporator during the defrost phase. A mechanical break in the heating filament prevents any ice removal, leading to a rapid 'snowball' effect where frost accumulates until it is visible in the main freezer cabin. Replacing the element restores the required heat flux for the automatic defrost process.
