Inverter Power Drive Assembly
The XV20i relies on an inverter to convert AC power into a simulated three-phase DC signal to drive the variable-speed compressor. The humming sound indicates the board is receiving line voltage but cannot properly commutate the power due to failed internal resistors or capacitors, resulting in a 'locked rotor' state where the motor vibrates at line frequency without rotating. Replacing the inverter assembly is the only reliable fix as these components are integrated and non-serviceable at the board level.
