Defrost Thermistor
This sensor monitors the evaporator temperature and sends resistance-based data to the control board to initiate the defrost cycle. If the thermistor's resistance value drifts, the board fails to recognize that the coils are at a temperature requiring defrost, leading to uncontrolled frost accumulation and blocked airflow.

Defrost Bi-Metal Thermostat
The bi-metal thermostat acts as a safety switch that closes when the evaporator is cold to allow current to reach the heater. If the internal contact points fail or the housing warps (losing its seal), the circuit remains open, preventing the heater from energizing and causing the evaporator to become a solid block of ice.

Defrost Heater Assembly
The heater is a resistive element designed to convert electrical energy into thermal energy to melt frost during the defrost cycle. If the internal filament undergoes a high-resistance failure or a complete break, no heat is generated, making it physically impossible for the unit to shed ice from the evaporator fins.
