Electronic Expansion Valve (EEV)
The EEV regulates the flow of refrigerant into the evaporator coil; if the stepper motor or valve body seizes, it disrupts the pressure balance. This forces the variable speed compressor to work against improper head pressures or ingest liquid refrigerant, causing loud mechanical resonance and a total loss of cooling capacity.

Inverter Control Board
The inverter board converts incoming power to a three-phase frequency to drive the compressor motor. If one of the power transistors (IGBTs) fails or leaks, the compressor will experience 'single-phasing' or phase imbalance, resulting in a loud electrical growl/vibration and insufficient RPMs to compress refrigerant.

Copeland Scroll Variable Speed Compressor
Internal mechanical failure of the scroll flanks or a broken internal discharge check valve will cause the unit to run loudly while failing to create the necessary pressure differential for cooling. This is often the terminal result of prolonged operation with a faulty metering device or poor lubrication return.
