Inverter Control Board Assembly
The inverter board is responsible for converting single-phase line voltage into a three-phase variable frequency output to drive the compressor rotor. Failure of the internal IGBT transistors prevents the generation of the electromagnetic field required for compressor startup. Because the outdoor fan operates on a distinct circuit, it can continue to run while the high-current compressor drive is in a faulted state.
