Linear Inverter Compressor
The linear inverter compressor is the mechanical heart of the cooling system, using a single reciprocating piston to compress refrigerant. In this model series, internal mechanical wear or discharge valve failure prevents the unit from maintaining high-side pressure, effectively halting the heat exchange process. This results in a complete loss of cooling in both the refrigerator and freezer compartments.

Main Power Control Board
This board contains the inverter drive circuitry that converts AC power into the variable frequency pulses required to drive the linear compressor. If the capacitors or the IPM (Intelligent Power Module) on this board fail, the compressor will not receive the electrical 'push' needed to start or maintain its stroke. This electronic failure mimics a mechanical compressor seizure.

Condenser Fan Motor
The condenser fan is responsible for drawing ambient air across the condenser coils to dissipate heat removed from the cabinet. If the motor bearings seize or the windings fail, the refrigerant remains in a high-temperature gas state, preventing it from reaching the liquid phase necessary for evaporation and cooling. This leads to a gradual then total loss of cooling performance.
