When your furnace runs the inducer and gas valve but never lights, a cracked or worn ignitor is the most common cause. This direct-fit silicon nitride ignitor restores reliable, fast ignition without the fragility of older silicon carbide designs.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20165703S (OEM Goodman)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Hot Surface Ignitor (HSI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement:\u003c\/strong\u003e Silicon nitride, high-durability\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 120V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Gas Furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e WFD18115S5CXCB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM 20165703S\u003c\/strong\u003e ignitor is manufactured to Goodman's exact resistance and bracket spec for guaranteed alignment in the burner assembly and consistent ignition timing. Generic universal ignitors often require adapter brackets, may not match the furnace's ignition control timing, and typically fail sooner. For a furnace you rely on through winter, the factory part is the confident choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy — 2 out of 5.\u003c\/strong\u003e Most homeowners can swap this ignitor in 15–20 minutes with a nut driver. Always disconnect power at the furnace switch and breaker before servicing, and handle the ceramic element only by its bracket — skin oils shorten ignitor life.
