Defrost Heater Assembly
This resistive heating element is subject to thermal cycling fatigue, eventually leading to a break in the internal filament. When this occurs, the frost buildup on the evaporator coils is never cleared, creating an insulating layer of ice that prevents heat exchange between the air and the refrigerant. Replacing the heater restores the thermal defrost cycle necessary for airflow.

Defrost Thermostat (L55-20)
The bimetal thermostat acts as a safety limit and cycle-terminator for the defrost heater. Over time, the internal contacts can pit or the housing can expand (blow out), preventing the heater from receiving power even when the defrost timer is in the correct position. Replacing the thermostat ensures the heater receives current during the defrost window.

Defrost Timer
The mechanical defrost timer utilizes a small synchronous motor and plastic geartrain to track compressor run time. If the gears strip or the motor stalls, the unit will never enter the defrost state or may get stuck in it indefinitely. This component is the 'brain' of the defrost cycle and is a high-wear mechanical part.
