Single Pole Contactor
The contactor is the electromechanical switch that bridges the 240V mains power to the outdoor inverter board. If the electromagnetic coil in the contactor fails, the outdoor compressor and fan will never receive power, preventing heat transfer. The indoor blower remains operational because it is powered independently by the furnace or fan coil circuit.

Pleated Air Filter (MERV 11+)
A heavily fouled air filter restricts the mass flow of return air across the evaporator coil, causing the refrigerant temperature to drop below the freezing point of the condensate. This leads to ice accumulation on the coil fins, which acts as an insulator and eventually blocks all heat exchange, resulting in the system blowing ambient-temperature air.

Inverter Control Board
In variable-speed models, the inverter board converts AC to DC to drive the compressor at varying frequencies. If the Integrated Power Module (IPM) or the communication bus on this board fails due to thermal stress or a power surge, the compressor will fail to initiate rotation, while the system's indoor components continue to run.
