HVAC Air Filter (MERV 8-11)
A heavily loaded filter increases static pressure and reduces mass airflow over the indoor evaporator coil. This causes the refrigerant temperature to drop below the freezing point, turning ambient humidity into a solid block of ice that physically seals the passages in the coil, preventing air from reaching the vents.

InteliSense Control Board
The InteliSense board manages the digital communication between the thermostat and the blower motor. A failure in the board's logic circuit or the integrated blower relay prevents the execution of the fan-on signal, meaning the motor never receives the electrical command to move air despite the system being in a cooling state.

Blower Motor Run Capacitor
The capacitor provides the necessary electrical phase shift to create the starting torque required for the blower motor to rotate. If the capacitor's capacitance drops below its rated microfarad tolerance, the motor will stall and hum but fail to spin the centrifugal fan, resulting in zero airflow.
