When your furnace fails to light, cycles on the safety lockout, or blows cold air, a cracked or aged ignitor is the most common culprit. This OEM silicon-nitride-style ignitor delivers reliable, high-temperature ignition and drops directly into the factory bracket with no modification.\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 (HSI)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFD18045S3AXCC furnace\u003c\/li\u003e\n\u003cli\u003eVoltage: 120V (matches furnace control board output)\u003c\/li\u003e\n\u003cli\u003eMount: Direct-fit factory bracket with plug connector\u003c\/li\u003e\n\u003cli\u003eApplication: Gas furnace ignition\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM Goodman ignitor\u003c\/strong\u003e is engineered to the exact resistance and heat-up curve the WFD18045S3AXCC control board expects, ensuring correct timing and long service life. Lower-cost universal ignitors can work but often require adapter harnesses, run hotter or cooler than spec, and fail prematurely. For a furnace you rely on through winter, the OEM part is the safe choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1 of 5).\u003c\/strong\u003e Shut off power and gas, remove the burner access panel, unplug the old ignitor, remove one or two mounting screws, and reverse the process. Handle the ceramic element by the base only — skin oils can shorten its life. Most DIYers complete this in 15–20 minutes. If you are not comfortable working near the gas manifold, hire a licensed technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058214781299,"sku":"GOODMAN-13830","price":47.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-hot-surface-ignitor-for-wfd18045s3axcc-20165703s","provider":"National HVAC Parts","version":"1.0","type":"link"}
