Defrost Bi-Metal Thermostat
This component is a temperature-sensitive switch that completes the electrical circuit to the defrost heater. If the internal contacts fail to close at low temperatures, the heater will never energize during the defrost cycle, leading to a massive ice build-up on the evaporator that eventually migrates into the freezer cabin. This is a high-fatigue part subject to constant thermal cycling.

Freezer Door Gasket
The magnetic gasket maintains a hermetic seal to keep humid room air out of the sub-zero environment. If the seal is torn or compressed, 'snow-like' frost will form near the entry point as moisture-laden air undergoes immediate desublimation upon contact with the cold interior. Replacing the gasket restores the pressure seal and prevents the influx of latent heat.

Defrost Heater
The defrost heater provides the radiant heat necessary to melt frost off the evaporator fins during the timed defrost interval. If the heating element has a fractured filament or internal short, the frost will continue to accumulate until it blocks airflow and visible ice builds up on the back panel of the freezer. This represents a total failure of the thermal removal phase.
