Inverter Power Drive Module
The Inverter Drive is responsible for converting AC power to a DC bus to modulate the variable speed compressor. If the IGBT bridge or the filter capacitors on this board fail, the compressor will not receive the electrical frequency required to rotate, resulting in a 'running' fan but zero cooling. This is the most common failure in high-SEER variable speed systems.

Electronic Expansion Valve (EEV)
Unlike standard systems, the XV20i uses an electronic stepper motor to meter refrigerant. If the stepper motor fails or the valve pin seizes, the refrigerant flow is completely restricted; the compressor may run, but no heat exchange occurs, resulting in the air failing to cool.

Variable Speed Scroll Compressor
The Climatuff™ compressor is the mechanical heart of the system. Internal mechanical failure or a winding short in the permanent magnet motor will prevent the creation of a pressure differential across the refrigeration circuit, meaning the system will cycle without achieving the phase change required for cooling.
