Linear Compressor Replacement Kit
The linear compressor uses a single-piston reciprocating motion driven by an electromagnetic field. Mechanical failure of the internal valve plate or the piston spring results in a loss of volumetric efficiency, causing the system to struggle with maintaining set-point temperatures, especially during high-load periods. This component is the most frequent point of failure in the Smart Cooling system for this model series.

Main Power Control Board
The Main PCB contains the inverter circuitry that modulates the frequency and voltage sent to the linear compressor. If the control logic or the inverter capacitors begin to drift, the compressor may cycle irregularly or fail to reach the necessary stroke length to achieve the required Delta-T. This results in unstable internal temperatures as the cooling cycles become unpredictable.

Refrigerator Thermistor
This model utilizes six temperature sensors to feed data to the Smart Cooling Plus system. If the thermistor's Negative Temperature Coefficient (NTC) resistance curve shifts due to moisture intrusion or component aging, the control board will receive 'noisy' or incorrect data. This causes the logic controller to prematurely terminate cooling cycles or over-cool, resulting in significant fluctuations in the cabin temperature.
