Could a failing Blower Motor Run Capacitor cause the GOODMAN GSZ14 to have symptom: No Air From Vents?

The run capacitor provides the essential phase-shifted electrical load to the motor's start windings to create the magnetic torque required for rotation. Over time, heat and voltage fluctuations cause the internal dielectric to break down, resulting in a loss of capacitance. Without sufficient microfarads, the motor cannot overcome its own static inertia, leading to a locked-rotor state and zero airflow.

Could a failing Indoor Blower Motor cause the GOODMAN GSZ14 to have symptom: No Air From Vents?

Physical failure of the motor occurs via two primary modes: thermal breakdown of the copper winding insulation leading to a short circuit, or mechanical seizure of the bearings. In systems paired with the GSZ14, if the motor is an ECM (Electronically Commutated Motor), the internal power module may have failed due to an electrical surge, rendering the motor unable to interpret the control signal.

Could a failing Air Handler Control Board cause the GOODMAN GSZ14 to have symptom: No Air From Vents?

The control board contains the blower relay which acts as the high-voltage gate for the fan motor. Forensic inspection often reveals 'pitted' or charred relay contacts caused by repetitive arcing during the startup inrush current. Once these contacts fail to bridge the circuit, the blower motor will never receive power regardless of the thermostat's demand for air.
