TL;DR
A gas igniter is the component that lights the burner in a modern gas appliance without a standing pilot — a glowing hot-surface element of silicon carbide or silicon nitride in furnaces, ovens, and dryers, or a spark electrode in cooktops and water heaters. Hot-surface igniters also act as part of the proving chain in ovens, where a weak igniter draws too little current to open the gas valve fully: the classic symptom of an oven that heats slowly or not at all while the igniter still glows.
