Blower Motor Run Capacitor
The run capacitor provides the phase-shifted current necessary to create the starting torque for the indoor blower motor. If the dielectric material inside fails or the capacitor loses its microfarad rating, the motor will stall or hum without spinning. This prevents any air from being moved through the heat exchanger and into the ductwork.

Indoor Blower Motor
If the motor windings have reached a state of thermal breakdown or the internal bearings have seized, the motor will fail to rotate despite receiving power. This is a common secondary failure following an unrepaired capacitor issue that caused the motor to overheat while stalled.

Integrated Furnace/Air Handler Control Board
The control board contains the logic and high-voltage relays that energize the blower motor. If the fan relay contacts have pitted or welded shut, or if the logic circuit fails to respond to the G-wire call for fan from the thermostat, the blower will not receive the voltage required to operate.
