Most are constructed from silicon nitride or silicon carbide. The igniter is located in the move of gasoline moving into the burners.

A different furnace problem to troubleshoot which is relevant to this is one of the safety switches getting open up. The tension switch is a safety change. Even so other basic safety switches include limit switches that may journey.
