When the thermostat calls for heat, this igniter electrically heats to incandescence and ignites the gas burners, delivering fast, reliable startup without a standing pilot. A failed or cracked igniter is one of the most common causes of no-heat furnace calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 20165703S\u003c\/li\u003e\n\u003cli\u003eType: Hot surface igniter (HSI)\u003c\/li\u003e\n\u003cli\u003eFunction: Electric burner ignition\u003c\/li\u003e\n\u003cli\u003eFit: Goodman WFM18090S4BXCC furnace\u003c\/li\u003e\n\u003cli\u003eConnection: OEM plug\/harness compatible\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine OEM igniter\u003c\/strong\u003e matches the original resistance, mounting bracket, and connector, so it drops in without adapters or rewiring.
