On each call for heat, the control board energizes this ignitor until it glows red-hot, lighting the burners. A cracked or worn ignitor is the single most common cause of intermittent no-heat and ignition-lockout faults.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 20165703S\u003c\/li\u003e\n\u003cli\u003eType: Hot surface ignitor (HSI)\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana OEM\u003c\/li\u003e\n\u003cli\u003eApplication: WFM18140S5DNCB and compatible gas furnaces\u003c\/li\u003e\n\u003cli\u003eMount: Direct-fit bracket to match original\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis factory \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e ignitor matches the correct resistance, element geometry, and bracket so it seats properly and ignites on the first cycle.
