Could a failing ECM Blower Motor and Module Assembly cause the CARRIER INFINITY 24 (24VNA6) to have symptom: No Air From Vents?

Variable-speed ECMs utilize onboard power inverters to convert AC to DC for the brushless motor. These modules frequently suffer from failure of the thermistor or internal capacitors due to high static pressure or thermal cycling, resulting in a motor that cannot initiate rotation despite receiving a signal.

Could a failing Infinity MERV 15 Air Purifier Filter cause the CARRIER INFINITY 24 (24VNA6) to have symptom: No Air From Vents?

If the media filter is loaded beyond the system's design static pressure limits, the communicating Infinity controller may detect a 'High Static' condition and shut down the blower to prevent motor burnout. In extreme cases, the dust load creates a physical barrier nearly impenetrable by the centrifugal blower.

Could a failing Evaporator Coil Assembly cause the CARRIER INFINITY 24 (24VNA6) to have symptom: No Air From Vents?

A refrigerant leak or restricted airflow can cause the evaporator coil temperature to drop below the dew point and subsequent freezing point. This results in solid ice encapsulation of the aluminum fins, which acts as a physical 'wall' blocking any air from passing through the air handler into the ductwork.
