Draft Inducer Motor Assembly
The 'humming' sound combined with a failure to ignite suggests the furnace sequence is stalling at the pre-purge stage. The inducer motor is responsible for creating a vacuum to close the pressure switch; if the bearings are seized or the internal windings are failing, the motor will hum under load but fail to rotate. Without this rotation, the safety circuit remains open, and the control board will never initiate the ignition sequence.

Dual Run Capacitor
If the 'Won't Ignite' symptom is the user's colloquial description of the outdoor cooling unit failing to start, a failed capacitor is the most common cause. The capacitor provides the necessary phase shift to create starting torque for the compressor and fan; failure results in an audible hum as the motor windings are energized while the rotor remains locked.

Hot Surface Igniter
Statistically, the most common failure for a 'Won't Ignite' symptom in a Bryant system is a cracked silicon carbide or silicon nitride igniter. While the igniter itself does not hum, the user may be hearing the inducer motor running normally and mistaking that sound for a problem while the igniter fails to reach the required temperature to light the gas.
