Combustion Air Inducer Motor Assembly
The humming sound indicates that the inducer motor is receiving line voltage but the rotor is locked or the bearings have seized due to moisture/corrosion. In the EL296V, if this motor fails to reach its target RPM, the pressure switch will not close, effectively halting the ignition sequence before the igniter or gas valve are activated.

Hot Surface Igniter
Statistically the highest frequency failure point in gas furnaces, the silicon nitride element becomes brittle and develops microscopic fractures over thousands of thermal cycles. While it doesn't cause humming, a total failure results in the ignition sequence timing out after the inducer starts.

Two-Stage Gas Valve
Internal solenoid coils can produce a 60Hz hum if they are energized but the internal plunger is physically stuck or blocked by debris. If the valve fails to open during the ignition window, the burners will never receive fuel for combustion.
