Refrigerator Thermistor
The thermistor is a Negative Temperature Coefficient resistor that provides thermal feedback to the control board. If the internal resistance drifts due to moisture ingress or material degradation, the control board receives inaccurate voltage signals, causing the compressor and fans to cycle prematurely or delay activation, resulting in wide temperature swings.

Evaporator Fan Motor
This motor uses a Hall effect sensor to provide RPM feedback to the microprocessor. If the sensor or the motor windings fail intermittently, the fan may fluctuate in speed or stall, preventing consistent heat exchange across the evaporator coils and leading to stratified air and fluctuating compartment temperatures.

Air Damper Control Assembly
The damper is a mechanical gate that regulates the flow of chilled air from the evaporator to specific zones. If the internal gearing or the synchronous motor fails, the damper may stick in a partially open or closed position, causing the unit to overshoot or undershoot the target temperature setpoint as it attempts to balance the thermal load.
