Temperature Sensor (NTC Thermistor)
The NTC thermistor monitors internal enthalpy and provides resistance feedback to the control module to regulate compressor speed. If the sensor's moisture seal fails, it causes 'drift' in the resistance curve, leading the control board to incorrectly cycle the cooling system or mismanage the damper doors. This results in temperature swings as the unit over-cools or under-cools based on false data.

Evaporator Fan Motor
This brushless DC motor facilitates forced convection across the evaporator coils. If the motor's internal hall effect sensor or bearings fail, the fan may rotate at inconsistent RPMs or stall intermittently. This prevents the even distribution of chilled air, causing localized temperature fluctuations despite the compressor maintaining the correct refrigerant state.

Power Control Module
The control module contains the PID logic for the inverter compressors and fan relays. A degradation of the electrolytic capacitors or a logic error on the PCB can lead to improper voltage modulation to the cooling components. This causes the system to fail in maintaining a stable steady-state temperature, resulting in erratic cycles.
