Inverter Control Board
The inverter board is the primary driver for the variable-speed compressor. In these models, thermal stress often leads to the failure of the power transistors (IGBTs) or the gate-drive circuitry. When this occurs, the system can still power the ECM fan motor but cannot provide the 3-phase electrical commutation necessary to rotate the compressor rotor.

Variable Speed Scroll Compressor
If the inverter board is functional, a mechanical seizure (Locked Rotor) or an internal winding insulation breakdown within the compressor itself will prevent startup. This usually results from refrigerant migration or long-term bearing wear that exceeds the starting torque provided by the inverter.

Suction/Discharge Pressure Transducer
The Infinity system monitors system pressures in real-time. If a transducer fails and reports a 'high pressure' or 'low pressure' condition that is outside of safe operating parameters, the logic board will inhibit the compressor from starting to prevent hardware damage, even if the fan is permitted to run to attempt to normalize temperatures.
