On a call for heat the control board energizes the silicon-nitride element, which heats rapidly to light the burners and, on combined igniter\/sensor designs, also confirms flame presence. Silicon-nitride HSP igniters are more durable than older silicon-carbide elements but still wear out with cycling. A failing unit causes no ignition, short cycling, repeated ignition lockouts, or a furnace that lights then drops out when flame is not sensed.
