Silicon Nitride Hot Surface Igniter
The igniter is a resistive heating element that provides the heat source for combustion. Over time, the constant expansion and contraction of the ceramic material leads to structural failure or increased electrical resistance. If the inducer motor is humming but no glow is visible in the burner assembly, the igniter is no longer completing the circuit.

Flame Sensor Rod
If the unit ignites for several seconds and then shuts down, the flame sensor is failing to transmit a micro-amp signal back to the control board. Carbon buildup on the rod acts as an insulator, preventing the furnace from confirming that a flame is present, leading to a safety lockout.

Draft Inducer Motor Assembly
The 'humming' may indicate a motor with a failing bearing or a seized impeller that cannot reach the RPM necessary to close the pressure switch. Without the correct static pressure confirmed by the switch, the control board will never send voltage to the ignition circuit.
