When the control board calls for heat, the ignitor element heats to a glowing temperature to light the main burners. Hot surface ignitors are a wear item — the brittle element degrades over thousands of heating cycles — and a cracked or open ignitor is the leading cause of a furnace that clicks but produces no flame.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 20165703S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Hot Surface Ignitor (HSI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e WFM18090S5CXCB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Gas Furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Electrically heated element that lights the main burners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e ignitor arrives with the correct mounting bracket, harness, and connector so it plugs directly into your furnace with no adapters.
