On each call for heat the control board energizes the ignitor, which glows red-hot to light the burners. Hot surface ignitors are one of the highest-wear parts in a furnace: the element becomes brittle with thermal cycling and eventually cracks, producing a furnace that runs the inducer and clicks but never lights. If your furnace is not igniting, the ignitor is the first component to inspect.\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 (silicon-nitride style element)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFM18090S5CXCC and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eConnection: Molex-style plug with mounting bracket\u003c\/li\u003e\n\u003cli\u003eCold resistance: check ohms per Goodman spec before condemning the board\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM silicon-nitride ignitors deliver the correct resistance and warm-up time the Goodman control board expects, and are far more durable than legacy silicon-carbide universals. Generic drop-in kits with adapter harnesses can work but often have shorter service life and mismatched glow timing. For the longest-lasting repair, choose the genuine OEM ignitor.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy to Moderate\u003c\/h3\u003e\u003cp\u003eOne or two mounting screws and a single plug connector. The element is fragile — handle only by the ceramic base, never the glow area. Shut off power and gas before servicing.
