Defrost Thermistor Assembly
This NTC (Negative Temperature Coefficient) thermistor monitors the evaporator coil temperature to communicate with the control board. If the sensor's resistance drifts out of the calibrated range, the control board will not initiate the defrost heater, allowing frost to accumulate on the evaporator fins until it migrates into the freezer cabinet. Replacing this component restores the feedback loop necessary for the automatic defrost cycle to execute.

Freezer Door Gasket
The magnetic vinyl gasket serves as the thermal barrier between the ambient environment and the freezer interior. If the gasket is torn, warped, or loses its magnetic pull, warm and humid air continuously enters the cabinet. This moisture undergoes a phase change (desublimation) upon contact with the freezer's sub-zero surfaces, resulting in the 'snow-like' frost buildup reported by the user.

Defrost Heater
The defrost heater is a resistive element that provides the thermal energy required to melt ice from the evaporator coils during the defrost interval. If the internal filament has suffered a continuity break, the defrost cycle will run its timed duration without actually clearing any ice, leading to a total failure of the defrost system and significant frost accumulation in the rear of the freezer.
