On each heat call the control board energizes the ignitor, which glows to light the burners. A cracked, worn, or open ignitor is the single most common cause of no-heat failures — this OEM replacement restores fast, reliable startups without weak or delayed ignition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20165703S\u003c\/li\u003e\n\u003cli\u003eType: Hot Surface Ignitor (HSI)\u003c\/li\u003e\n\u003cli\u003eElement: Durable silicon-nitride style igniter\u003c\/li\u003e\n\u003cli\u003eFunction: Direct burner ignition on heat call\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFD18090S4BXCC and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana compatible)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM option\u003c\/strong\u003e delivers factory-matched resistance and glow characteristics for correct board timing and long service life.
