When the thermostat calls for heat, the control board energizes the igniter, which glows red-hot and ignites the gas at the burners. Over thousands of heating cycles the silicon-carbide or silicon-nitride element develops hairline cracks and fails to reach ignition temperature — the most common cause of a furnace that clicks, runs the inducer, but never lights.
